Speaker Size for Home Theater?

Speaker Size for Home Theater?

Message : I am looking for a pair of in wall speakers to use as rear surround. I am looking for really great sound. I am looking at the 8″ because the ones you have are three way.

Please suggest what you think are the best for around $200. Also I want to be able in the future go with the same company for front and center in wall.

Thanks, Scott


As quoted here:
Speaker Size for Home Theater?

Generally 6 1/2″ speakers work best for home theater in-wall and in-ceiling speakers. You’re already going to be using a powered sub-Woofer for your theater room and that will take care of the low, low bass sounds. A subwoofer handles frequencies from about 120 hertz and lower (the low, boomy sounds).

Some people we have talked to wanted to use 8″ speakers for their home theater, because they figured “bigger is better”.  An 8″ speaker is made a little larger so it can reproduce lower sounds better. But in a home theater application, those sound ranges are already being handled by other equipment, and it would only be redundant.

So, when I get asked: What Speaker Size for Home Theater, a 6 1/2″ speaker will produce sounds from 80-100 hertz on up (mid-range type sounds like snare drums, gun shots, and snaps and higher). If you use the 8″ speaker in your home theater realm it will be slower to react to those mid-range noises than the 6 1/2″ speaker will because of it’s larger mass. Just like a sports car will be quicker off the line than a big truck.

In a theater type system when using a subwoofer, you are actually
creating a three way system. Your woofer is one, the mids are the
woofer in the wall/ceiling and the tweeters are the third way. So
you`ll get all the good midrange you`d expect out of a three way system,
it just might look a little different in the end.

So the speaker size for home theater?  Generally, smaller because you’ve got the subwoofer.

As for a recommendation, take a look at the speakers that have the
closest match for the type of material you have on the front channels of
your system now to match up the “timbre” or characteristics of the type
of sounds that come from the speakers. Here are some recommendations for Theater Kits here:



Volume Control True Off Position

Can you tell me if the phoenix gold VSL125-RB volume control has a true OFF setting? If not is there one with a true OFF setting? I had heard that w/o this then there is a small amount of sound coming from the speakers even with the volume setting at the lowest?



Nope. None of the impedance matching versions out there will have a true off setting, where it totally disconnects from the circuit.

This is because the function of the impedance matching is that the whole circuit needs to remain constant. Meaning that the amp sees 8 ohms of impedance all the time. If one were to be taken out of the circuit, the impedance would change, going up in value, thereby all the other speakers would get more quiet. Which would be undesirable.

But I haven’t experienced that bleed thru with any of the volume controls at all. If you have your system properly initialized with most all of your volume controls set correctly, you shouldn’t hear anything when you turn one off.

Another option to avoid it completely would be to use a speaker selector as your impedance device and when you need to confidently turn off an area, use the button on the speaker selector. Speaker selectors take the leg completely out of the circuit. In this case, you’d use just regular volume controls with no impedance matching.



Impedance Matching Volume Controls vs. Speaker Selector Question

Everything I read indicates I need to connect my receiver to an impedance matching speaker selector, from there to each room’s volume control and speaker pair. If I have impedance matching volume controls in each room, why do I need a speaker selector? What does the speaker selector actually do? Can I run parallel to each room’s volume control directly from the receiver without a speaker selector? Thanks.

Typically, in a home situation we suggest a speaker selector with standard volume controls because you can turn off areas that you wouldn’t normally use and those areas truly get taken out of the circuit. Then the other areas get more power and better sound.

In an application that you would have all the areas on most all the time, you could (and should) use just impedance matching volume controls only. When you turn down an impedance matching volume control to it’s “off” position, it’s not truly off on the back side of the circuit. It has to remain in the circuit or else the circuit would always be changing the load to the amp, therefor causing volume fluctuations everywhere anytime someone even makes one click of an adjustment.

So you can do it both ways. The downside to using the speaker selector method is that it costs a few more bucks.


Ceiling Speakers in Outlet Boxes

 Message :
 My new house has the ceiling prewired for speakers. It has the small cream color standard plastic covers now. Can I install speakers without cutting more into the ceiling? Can I use the existing space to mount speakers? Can the covers be color matched to the ceiling or do we paint them? Do you also sell the electronic equipment needed to create a surround sound system?


You can mount round speakers in such a way to cover the hole made by
those boxes. You just have to be careful on placement of your template
and cut just to the the edge of those corners.

Then, your only problem left is rotating the dog-ears into position.
There will be one that rotates up against the stud you`re working on.
You rotate that one out before you insert the speaker into the opening,
then twist the whole speaker frame to snug up against the stud and
tighten down.

All the speakers can be painted.



Theater Wiring Questions


You should be able to do the work yourself without too much trouble.

I`m glad to see you have looked over the FAQ`s.

As for the theater, a 5.1 type system like you`ve described is perfect
for most of our customers unless your room is really long, over 25 ft.
front to back. If yes, then your should consider the side wall type
speakers to fill in the large gap.

You can run the one additional pair of speakers off most of the
receivers out there today by hooking to the “B” pair of front speakers.
Keep in mind that you need to turn off all the surround modes to hear
music through those auxiliary speakers.

We do sell wire in as little as 100 ft. spools here:

The connections are all just bare wire type connections. You can use
these wall plates if you want to clean up the install behind your gear:

I found a great buy on a Pioneer VSX-1014TX Receiver, and a Sony DVD/CD; Then, sadly, the installer came down with a spinal Cancer and was unable to do the work.

Ceiling Theater Question


It will be just fine up there. Just as good as it would be in just a
standard ceiling if that`s where you have to go.

The one thing that I typically do with a drop ceiling tile type
installation is, use a piece of hardboard (pegboard without the holes)
cut about 14″ x 14″ with the hole cut out of the middle to use as a
backing plate. It will stiffen up the ceiling tile a bit and give some
better mid-bass response.

The back being open isn`t a worry.

Make sure you use a sub in the system.

Whole House Audio Question


The Receiver you mention is really made for surround sound applications.
The “channels” it has are for the decoded section from movies to be
played back at the given positions of a home theater.

The more practical set up for you might be a set up with two basic
“stereo” type receivers with two speaker selectors.

Your other more basic option for whole house music is to have just one
receiver with an 8 pair selector.

By having two receivers you`ll have the ability to play two different
things at the same time in your two “zones” that are set up with your

No problem not having the volume controls, they are optional with the
use of a speaker selector.

The speaker wire is 16 gauge, and the wire “runs” are all less than 100 feet. I now need to purchase a receiver to power these speakers, and am considering the RX-8040B Audio/Video Receiver by JVC.

Speaker Selector and Volume Controls

Speaker selector and volume controls question from Robert Schimmel:

Message :
I have wired my house for speakers; two rooms with one pair, and one room with a single dual channel speaker. The wires exit the wall by my by my stereo at a two gang box. Each room has a box for a volume control. Can you suggest what I need to complete the installation (i have speakers). speaker selector? wall plate? volume controls?
thanks, roger schimmel


Sure, a basic speaker selector like this one:
