5 Tips For Better Home Theater Sound

If you are not getting the rich home theater sound you paid for, there are a few vital sound checks and components that will deliver a perfect audio performance every time. Check your sound equippment for proper configuration and be sure that you are using the correct speakers for your system.

Home theaters are expensive, and when they are not working properly, the repair and replacement costs can be sky high. If your audio system is not up to par, there are few things you can do before calling a repairman or replacing the components. Try these five easy steps for inspection, adjustment and a do-it-yourself approach to crystal clear sound.

1. Matched Speaker System.

When one of your speakers goes out, there is a temptation to buy what’s on sale rather than matching your speakers with the manufacturer suggestions. If you must replace a speaker component, be sure that the new speaker is the same as the original unit sold in a sound ensemble. This will ensure you receive an even tone and quality of sound. In addition, your speakers should be raised on stands or brackets, careful to ensure they are placed at the same levels to project the sound evenly across the room. Match them with their elevation and angle in the direction to reach your listening center.

2. Speaker Alignment.

To optimize your listening pleasure, be sure that the speakers are placed in a strategic position in the room to deliver the sound to the sitting area. In some cases, one speaker is too far from the listening center and can throw the volume balance out of whack. The speakers should be turned to the listening area and placed an equal distance away. In addition, be sure to keep fabric furniture out of the way of the immediate area of the speaker, as this can cause an unequally balanced absorbing of sound.

3. Power Up.

Home theaters set up in larger rooms may need the assistance of an amplifier to project the sound. Not every speaker system is equipped with an amplifier jack, but you will find out by checking with your owner’s manual or inspecting the back hook-up panel for an amp jack reception.

4. Adjust The Bass.

If your bass performance is too deep and gravely, lower the tone quality to fit the size and acoustics in the room. Living spaces with hardwood floors or tile will elevate and transport sound must faster than carpeted areas. You may need to make an adjustment to tailor the bass speaker to accommodate the construction of the viewing room. In cases where the floor is tiled, just adding a few throw rugs are sufficient to absorb the echo effect and deliver a better quality of sound.

5. Upgrade Your Cables.

By using sturdier and commercial grade cables, the delivery of quality sound may be enhanced. Cable replacement is one of the most cost effective ways to improve your audio performance, and they should be replaced and upgraded when the audio system crackles or loses some of its power.

Understanding The Right Home Theater Surround Sound Speakers

When it comes to considering the installation of a home theater in the living room, den or family room, it is important that all of the audiovisual services are engaged throughout the components of this type of system. Therefore, it is critical to have a good video screen that movies can be watched on or that games can be played. In addition, one of the other major factors of a good entertainment system is the quality of the sound.

Therefore, in order to capture the entertainment quality of sound, upon the ear and vibrations against the body, it may be appropriate to purchase home theater surround sound speakers. Subsequently, it is important to know what surround sound is and home theater surround sound speakers are.

What is Surround Sound?

Before purchasing new technological equipment, it may prove to be beneficial to demystify some of the terms and words utilized to define some of the technology that is available to consumers today. One such word or technology that is available today is surround sound.

Therefore, surround sound is as simple as it sounds. Specifically, it is the listening of sound coming from all directions as the listener enjoys a TV show, movie, plays a video game, listens to music, etc. In other words, surround sound is multi-directional and in turn increases the quality of the sound reproduction through various audio sources, speakers and channels.

What are Home Theater Surround Sound Speakers?

However, in order to enjoy surround sound there are many features that are required that will help to funnel or provide a conduit for this surround sound technology. Some of those features include a sub-woofer, receiver and home theater surround sound speakers.

Obviously, all of these components are important. However the quality of the home theater surround speakers is critical because this is where the sounds emanate from. Generally, an adequate home theater surround sound speakers set includes two front speakers, a center speaker, subwoofer and a minimum of two speakers in the back portion of the home entertainment area.

When considering the selection of home theater surround sound speakers, it is important to consider a number of factors. Some of those factors include the reputation of the manufacturer as well as whether the home theater surround sound speakers are within the individual’s budget or not. Some of the reputable systems could include the Pioneer home theater speaker system, systems made by Sony, Panasonic, etc.

Of course, it is important to listen to the quality of the home theaters on surround sound speakers. This can be accomplished by going to various electronic stores, going to a friend’s or family member’s home that has a home theater surround sound speaker system. This can be especially helpful in deciding what sound system to purchase.

You can achieve movie sound quality at home

Have you ever gone into a movie theater and wondered how they make the sound so crisp and clear with no distortion, how the bass and treble are perfect to the ear?  With no doubt, the thrill of watching movies at the theater comes from outstanding sound which echoes through the room.  You can achieve similar sound quality from a good home theater system.

 

Many home theater systems are only as good as the speakers.  You go to extreme measures setting up your system; you have the big screen television delivering HD quality picture; the media room looks great, the furniture is first rate but something is missing……..quality sound.

 

Enter Bose.

 

A Bose Home Theater has new age technology, which incorporates some outstanding features.  The Lifestyle V30 has it all!

 

Imagine watching the movie Jurassic Park when the T-Rex is fighting the rapture, the sound that surrounds you from the Bose Home Theater Lifestyle V30 will encapsulate you, seemingly putting you in the middle of this fight.  Having this kind of system is priceless.

 

Great things come in small packages, no exception here.  No huge, clumsy speakers to cluttered a room, in fact you’ll be wondering where the sound is emanating from.

 

One great feature that I like is that the Bose Home Theater Lifestyle V30 has Digital Dynamic Range Compression Circuitry (DDRCC). This lets you hear soft sounds, even at low listening levels, no adjusting the volume level here.  This system also has an abundant of inputs- 4 external video sources just to name a few.

 

Bose Home Theater has kept the consumer in mind with the Lifestyle V30.  This is a complete home system which does not require integrating with other components.

 

Equal parts of a home theater system are great picture and great sound.  The Bose Home Theater Lifestyle V30 is the perfect addition to any home theater.

Wiring A Home Theater Surround Sound System – Do Not Just Stand And Wait, Try It Out

Home Theater : pragmatic concerns

Today’s consumers are much more savvy than they’ve been in days past. Perhaps this class when it comes to studying about the products we spend our hard-earned money on is the results of instant info at our fingertips thru the Net or a deep need to grasp more about where our cash is going.

In a number of ways this is wonderful stories. More consumers are opening up to the idea of home theaters. In truth, this is becoming a selling point in many houses across the country. It’s a smart idea to research the products you will purchase and the individual parts of your house theater system but how much time have you invested towards the planning and design of your house theater?

What, of your existing home entertainment equipment will you be keeping and which pieces of equipment, if any, will you be replacing? I usually advocate purchasing one element at a time and building a home theater system rather than simply going in and purchasing a box off the shelf which has everything in one place. While you can get a really pleasant system by doing this, I think you will ultimately get more bang for your buck if you build your own system one piece at a time and select each piece for the individual qualities your like. That having been said, after you get the components home you must be ready to install them and assimilate them into your present home theater.

Will you be adding special home theater seating or going with a gigantic comfy couch? This matters when planning the layout for the room in which you’ll be watching one thousand your movies and television favorites. We enjoy being comfy as we watch 24 hours of non stop action or the nearest planet in a far off solar system explode. Do you have a plan for providing that comfort in your house theater?

The next question is how do you plan to cover all the equipment? While wiring a home theater surround sound system could appear like an excellent idea, they are killers to your bottom line should you want to some day sell your house as they eat floor space and not everyone will appreciate your home theater. Because of this, I recommend a floor-to-ceiling entertainment center with doors that may be closed around the features you aren’t using at any given moment.

While there isn’t any wrong or right when it comes to planning a home theater for your family, there are practical matters that are well worth considering. I hope this has brought to mind a few of those and you are packed with wonderful ideas for your current or future home theater.

Home Theater Setup (surround Sound Speaker Setup)

Home Theater Setup (Surround Sound Speaker Setup)

I am going to assume that you already have a surround sound or home theater amplifier or receiver. There are 3 main home theater speaker configurations which you will see termed 5.1, 6.1, and 7.1 channel surround. You will also see mentioned the terms Dolby Digital, DTS, and Dolby Pro-Logic. There are some other formats such as Dolby Digital EX, Dolby Pro-logic IIx, Dolby TrueHD, DTS neo:6.1, DTS-ES, TrueSurround XT, and undoubtedly more, but they do not need to be addressed separately as the information below is also relevant for them.

Let’s dispense with Dolby Pro-Logic first: if your receiver is only Pro-Logic (only older receivers at this point) you do not need to worry about 6.1 or 7.1 surround because your system can’t use the extra speakers. The two factors relevant to our discussion are:

1. how many channels does your system permit, and
2. Do you want to buy that many speakers?

All the receivers that support more than 5.1 channels will also work fine with a 5.1 channel setup. Obviously, 7.1 will provide better surround sound than 5.1, but at the expense of two extra speakers. If you have a limited budget you will have to decide whether to buy 5.1 higher quality speakers, or go for cheaper speakers to allow for 7.1 channels. By the way, the .1 channel is the home theater subwoofer. The subwoofer is really needed for home theater. A system will work without it, but I don’t recommend going without for home theater. The center channel is also very important for home theater, serving to anchor the sound to the video screen. These are the recommended placements according to Dolby Labs.

5.1 surround system:

A). Center speaker centered on video source

B). Subwoofer(s) in an arc with the main L & R speakers between speakers and video source

C). L & R front on a 22-30 degree angle from the sitting, on an equidistant arc connecting the center channel and subs

D). L & R surround equidistant and on a 90-110 degree angle from the sitting position

6.1 surround system:

A). Center speaker centered on video source

B). Subwoofer(s) in arc with the main L & R speakers between speakers and video source

C). L & R front on a 22-30 degree angle from the sitting, on an equidistant arc connecting the center channel and subs

D). L & R surround equidistant and on a 90-110 degree angle from the sitting position

E). Rear center 180 degrees (directly behind) the sitting position

7.1 surround system:

A). Center speaker centered on video source

B). Subwoofer(s) in arc with the main L & R speakers between speakers and video source

C). L & R front on a 22-30 degree angle from the sitting, on an equidistant arc connecting the center channel and subs

D). L & R surround equidistant and on a 90-110 degree angle from the sitting position

E). L & R rear equidistant and on a 135-150 degree angle from the listening position.

The descriptions above are the specifications for speaker placement according to Dolby Labs.

Subwoofer Setup

Your subwoofer may have a switch for Dolby Digital / Pro Logic. If your receiver is only capable of Dolby Pro Logic (only older systems) you need to use the Pro Logic inputs and set the crossover frequency properly to match with your main speakers. You may use an 80 Hz setting and adjust the volume properly for a reasonable output. I will not go into this further as almost all systems are capable of Dolby Digital output. If you have a Dolby Digital capable receiver (assuming you are using the sub for home theater purposes) set the switch to Dolby Digital even if you are using a Pro Logic source. The reason for this is that it allows your home theater receiver to manage the bass output & crossover frequency of the bass information. Your receiver will ensure the proper output to the sub in the case of Dolby Pro Logic source material. If you use the Pro Logic inputs only, Dolby Digital programs may not be reproduced properly. The same goes if you have multiple inputs on your sub. If your input is labeled LFE it is the equivalent of a Dolby Digital input. You want to use the input to the RCA style plug (or plugs) if you are using the subwoofer in a surround system. If you have speaker level binding post inputs, these are almost always for using the subwoofer in a non surround sound speaker setup. Preset the subwoofer level control to about halfway before running the white noise test tone to calibrate your receiver speaker levels. You absolutely must run the test and balance your speaker levels to have the surround system perform properly. Don’t worry about the crossover frequency control on the sub for Dolby Digital or better systems. For Pro Logic set it to the point where bass in your main speakers drops off, (or 80 Hz if you can’t find any info, and adjust from there for best sound) which will require looking at the documentation for your speakers.

If you are not using your sub in a surround system, you may, with advantage, use the speaker level inputs on the back of your sub. If you have relatively small speakers without much bass output this can provide a substantial sound quality advantage. The receiver left and right channels are connected directly to the subwoofer, and the left and right speakers connect to the speaker out connectors on the subwoofer. What this does is allow the sub to produce the low bass that the main speakers can not, which of course the other types of connections would do also. The advantage here is the fact that with the subwoofer connected this way, it filters the bass out of the signal to your main speakers, so they speakers never try to produce the bass that they can’t handle. This results in clearer, cleaner sound and more volume capability from your main speakers.

Subwoofer placement is generally as below for other speakers. It is true that bass is omni directional and so you should be able to place a subwoofer anywhere, but as usual this depends on your situation. I play music loud, and can detect where the subwoofer is located by the feel of the vibrations. I find it very distracting to have the bass seem to come from the front of the room, but the vibrations of the bass coming from another direction. I therefore always prefer a subwoofer to the front of the room. The subwoofer should be adjusted in accordance with the setup (pink noise test) procedure of the amplifier it is being used with, if on a surround system. This usually means a crossover point of about 80Hz. If you have a phase switch or knob, set it to the position where the bass sounds the loudest. I also notice that most manufacturers recommend the sub be placed to the front of the room on a horizontal line with the main speakers. (Actually, to make all the speakers an equal distance from the listening position, they would form an arc.)

How to get the most out of your speakers & How to improve your sound quality for no extra money (unless you need speaker cable!)

The first consideration with a new speaker system is placement, and the second is wiring, both of which deserve consideration. We will cover wiring first with some generalities that apply to all kinds of speakers. The placement part will cover in home speakers only.

Wiring your speakers

First and foremost, wire selection can be very important. If your speakers are to be installed in-wall, you will need speaker cable rated cl3 or equivalent. If outdoor speakers, you should try to use what is termed a “direct burial” cable or equivalent.

Next, if you care about the sound quality at all, 22 gauge cable is not recommended. It can be used for very short runs, and is smaller for hiding, but due to resistance you will sacrifice some sound quality. I would recommend 16 gauge wire for most runs, unless you really want to get the best out of your speakers, in which case use 12 gauge or larger. For a long run I would recommend larger than 16 gauge cable. Click here to see our cable article and distance chart. I personally use a good audio quality 12 gauge cable myself, but you will pay more for cable this large. The advantages are better dynamics, and the amplifier can control your speakers better due to low resistance wire. As always, let the price point of your speakers determine the cable. Don’t put expensive cables on cheap speakers, and vice versa. BTW, don’t try to use romex (house wiring) instead of decent quality audio cable. Really, just say no. For so many reasons.

One common question is if fancy cable makes any difference. I must state here that many persons consider the very subject to be so much snake-oil. I personally believe that I can hear some differences, depending on the quality of the associated system. In other words, any hearable differences in cable will be more noticeable in a system with more resolution. Also consider that many listeners not selling cable claim to hear a difference. Consider any double blind tests carefully. I usually can pick holes in the logic behind most of these tests, and point out factors not considered. One perfect example was an amplifier test (by a major audio magazine) that level matched the amps, did a double blind test, and asserted the amps sounded identical, so they recommended that everyone buy the cheaper amp. Here’s the rub: Under their exact conditions, which are not normal listening conditions, the amps sounded the same. Consider this unmentioned idea: The cheaper amp had less power output than the other, and under normal listening conditions, say with loud rock music, and inefficient or difficult to drive speakers would have pooped out before reaching satisfying listening levels, not to mention clipping and distorting from overdriving the amp. One problem with the double blind tests is, in order to be accurate, they have to control every factor in the universe that could affect the results, even unknown factors. The other is, in order to compare everything on an even playing field, they purposely diminish or nullify the differences, then triumphantly proclaim they are all the same. The perfect example from above is level matching at a volume level that does not stress the more easily stressed amp.

Polarity or Phasing of your speakers is very important. This means finding the wire with a stripe or writing on one side, and connecting that wire to either the + (red) or -(black) on the amplifier and the speaker. It does not matter whether the stripe on the wire connects to plus or minus, as long as it is the same at both ends, and on all speakers. I always connect the plus to the stripe, just to be consistent. If you get this wrong you will lose almost all your bass response, and voices will float around instead of being centered when they should be.

Home Speaker Placement

Ideal placement for best sound is going to vary with the type of speakers you have, but we can supply some good generalities. Obviously, for a surround system, you have some built in limitations. The center channel needs to go above or below center of your television, (or perhaps centered behind a projection screen) and the left and right front need to go to the left and right front. So on for the rest of the speakers. It should be added at this point that for surround sound placement the ideal is all 3 front speakers an equal distance from the listener. This actually places the front speakers on an arc. It is generally good to put rear surrounds a little higher than ear level so that all listeners get a better chance to hear all the speakers. Leaving aside the obvious details of surround sound, here is how to improve the sound of your system for free.

First, don’t put anything in front of your speakers, and if they are placed in a cabinet make sure that the front of the speaker is even with the front of the cabinet. Also, keep in mind that some speakers such as the rear ported variety perform very poorly in cabinets. Make sure speaker ports, which may be in the front, rear, side or elsewhere, are not blocked. This goes for subwoofers also.

Stability is also important, your speakers need to remain stable at high volume levels. If they move with loud drum beats, your system will be robbed of punch and impact. If you use speaker stands make sure they are stable enough for the size of speakers you have. One quick tip is to use some blu-tack or mortite putty between the speaker and stand to improve the coupling and add stability. Spike on the bottoms of the stands work well for carpeted rooms.

Next, check out the sound of your speakers. Generally, most speakers sound better when aimed directly at the listener, and located at ear height. This is not always the case, however. If the treble or voices sound a little too sharp, then perhaps the speakers will sound better aimed straight out instead of at the listener.

Listen to the bass. Is it boomy, or lacking? If your speakers sound a little boomy, like they are in a barrel, bass response can probably be improved by moving your speakers farther from a wall or corner. If your speakers are too lightweight in bass, they may sound better closer to a wall. Remember not to block any bass ports. If the speaker is rear ported it needs a little space out from the wall and clearance on the sides of the speaker to perform properly.

One little tweak you might try: some speakers sound better with the speaker grills off. Try removing them and see if they sound better. In many cases there will be no noticeable difference, but it costs nothing to try.

Other issues:

If your speakers are correctly phased as described above but voices are not sharply locked in location you may have your speakers too far apart. This generally applies to stereo, not surround sound.

If not used on a surround system, the subwoofer crossover point should be adjusted to coincide with the drop off in bass from your main speakers. You may find this listed in your documentation, usually on the order of the -3db point. If your speakers still don’t seem to perform like they should, you should consider whether the amplifier attached to them is up to the task of driving them. There are more issues here than power, especially impedance. An amplifier that has high wattage may drive 8 ohm speakers well, and do very poorly on 4 ohm speakers if the amplifier is not designed for “high current” or rated into 4 ohm speakers. In addition, many amplifier (or receiver, home theater amplifier, etc) manufacturers use various methods to exaggerate the wattage ratings on their amplifiers. The true rating to look for is called the RMS rating, and should be rated into a specific impedance (4 ohm, 8 ohm) etc and at a specific distortion rating. This does not imply that all amplifier & receiver manufacturers that use terms such as a ‘Dynamic Power Rating’ are trying to deceive consumers. In some instances (such as with NAD equipment) such figures can be very meaningful. Just make sure you are comparing apples with apples, and use the RMS rating as a baseline for comparison. If ALL other factors are equal, the one with a higher dynamic power rating can have more punch and impact.
