How to Buy Surround Sound Speaker

Buying Surround Sound

Surround Sound Basics
The two main ingredients you need for surround sound are a multichannel speaker system, typically with five or six speakers, and a digital surround (A/V) receiver. You can’t get surround sound without both of these anymore than you can play tennis without both a racket and a net. (We’ll assume you already have an HDTV and a DVD player.)

You might think there are just too many speaker systems and receivers to choose from. But the buying process isn’t as complicated as it seems once you narrow down the choices to what best fits your needs. You can start by answering these questions:

• What’s your budget? If you’re working with a grand or less, you’re obviously going to have far fewer choices than if you have a bigger bankroll. Either way, you should set aside at least a few hundred dollars for the receiver and maybe twice as much for the speakers, since they pretty much define the system’s sound. Cheap home-theater-in-a-box packages are, well, cheap, so they have to make compromises — especially in the speakers — to achieve those prices. You can forget about high-performance sound. It also doesn’t make sense to spend beaucoup bucks on gargantuan speakers and then try to drive them with a low-power receiver — or to buy a megawatt receiver to drive a set of minispeakers.

• How big is your room? You need a system that can produce enough sound to fill your room. So if you have a large room — say, 20 x 30 feet — don’t try to get away with little cube speakers. And if you have a small room, it doesn’t make sense to have space-hogging tower speakers.

• Do you like it loud? Room size isn’t the only thing that determines maximum volume. If one of your goals in life is to experience the Star Wars Trilogy at Death Star-splitting volume in your cavernous den, you’ll need bigger speakers and a more powerful receiver than those of us with more reserved tastes and smaller rooms.

• How much gear do you have? Make sure the receiver has enough inputs for all of your audio/video source components. As receivers go up in price, the number of inputs and outputs you get increases. A small bedroom system with just a cable box, DVD player, and TV won’t need a receiver with as many connections as an all-out installation with a DVD player, high-def cable box, TiVo hard-disk recorder, game system, VCR, and so on.

Surround Sound Speaker placement for a tricky room

Time for a test

As you can see, the L-shaped couch is backed against a wall on one side, which makes it impossible to place a Surround Left speaker there unless it is mounted on the wall. That should be doable, but not without problems. Specifically:

- the speaker will be in FRONT of the prime listening position, not behind or even level with it

- the farther it's pushed back, the closer it would be to the center listening position; if level with the listener, it would be only inches removed from his face

This is a classic example of the problems which placing the TV in the corner of the room creates. I personally would place the TV against a flat wall (on right) and thus make the prime listening position on one side of couch. Or move the couch. If you are serious about surround sound speaker placement quality, your couch needs to move.

More on placement

This is a great resource for Home Theater Design. This talks about speaker placement for the very advanced person. So if you are really serious about converting a swimming pool or converting your children's room (who are now in college of course.) You should look at this resource

Speaker Placement according to Dolby

Throughout this blog I've been feeding your hunger for information on Surround Sound Speaker Placement. I've already given you the basics in previous posts (you can scroll down to see these), covering the placement of center, front and rear speakers.

Dolby has a very neat interactive diagram which goes into more detail on the subject. In summary it goes like this:

1. First find your seating position, ideally, this should be directly in front of the TV
2. The front right and left speakers should be on the side of the TV, but angled to face you, and this angle should be between 22 and 30 degrees. (Stay with me...)
3. The rear right and left speakers should be either directly to the side of you, or slightly behind, creating an angle of 90 degrees (directly to your side) to 110 degrees (a bit behind you).

So, and there you have surround sound speaker placement according to the bosses themselves, Dolby.

Diagrams on speaker placement

Here is a diagram from a website on speaker placement.

It's perfect, other than the fact that the subwoofer should really be in the corner for best results. You'll be surprised how much 'thump' you lose by not placing the subwoofer in the corner (any corner) of the room. Even regular speakers produce more lower frequencies when placed in corners of rooms.

You can view the website on surround sound speaker placement here.

Surround Sound Speaker Placement - Step by Step

Here's a good article on surround sound speaker placement.

It consists of 6 easy steps that just about anyone should be able to follow. Essentially, they are a summary of my own tips below.

The Subwoofer

This is very important: Place the sub in a corner of the room. It doesn't really matter which corner because no-one can tell where low frequency sound are coming from. The Speaker Placement of the subwoofer is very important indeed.

Rear Right & Left Speaker Placement

These speakers should be placed to the rear of the room facing the front. The Audio which comes out of this room are effects and background noises.

Front Left & Right Speaker Placement

These are to be placed to the left and right of the monitor. It’s not extremely important how far they are from the monitor and centre speaker, as long as they are placed the same distance from the monitor on either side for a balanced sound. Audio which comes through this speaker is music and effects.

Center speaker Placement

Place this speaker directly above or below the monitor or projector. Audio which comes through this speaker is dialogue, which always wants to be heard coming from the scren, no matter where in the room you sit.

Overview of Surround Sound Speaker Placement

Hi, I'm Joel and I've started this blog to show you how surround sound speaker placement can make or break your home cinema experience. It's too easy for people to place all their speakers in one place. However, the surround sound experience is lost with this sort of behaviour.

It's more than placing speakers randomly around the room. The definition of good speaker placement is to hear how the recording was meant to be heard.
