This work?

It will sound terrible.
Do this experiment, cup your hands, place in front of your mouth (megaphone like) speak a sentence, what does it sound like?
Subwoofer with open door or mesh would be probably be fine.

The speakers within the "walls/top bottom" of the cabinet will have a distorted boxy sound.
I didn't notice that the sub was turned sideways, thought you would be opening door or replace with mesh for sub, so it would NOT be a good idea to close off/block sound from sub as in picture.

Most speakers are designed to be in the open air, away from walls. "Bookshelf speakers" are best placed on stands, not bookshelves. A corner is not usually the best place for a sub, and putting one in a cabinet is like putting it in two or three corners at once.

What makes you say that it will sound terrible?

First of all you are talking about two completely different freq bands that have very different wavelengths and therefore very different directional characteristics.

Second, what you are describing about cupping your hands is a poor horn at best (well designed horns don't sound that way).

Third, There is no horn involved in the setup he is looking at.

Even if the sub is facing backwards (whch is the way I would start off doing it), he will get beneficial gain from the wall and by energizing two of the boundaries (floor and wall) he will excit more of the room modes, so the bass will be more even throughout the room.

At worst case he should maybe pull the stand a little bit off the wall ( say 6-10" or so) so as not to constrict the sub wavelengths.

I think he will be just fine.

Now getting a sub that will perform to his liking that will fit inside the cabinet may be a different story-but that depends on his needs in the sub department.

Yes he will get an early reflection off of the shelf, but it iwll be very early and will direct the energy up into the ceiling.

Agreed that having the door a mesh and STILL opening it would be better.

Of course there will not be a very wide stereo image-but that is part of the price you pay for having speakers close together.

But I cannot see in any case it will sound like you describe "a cupping of the hands".

Do you have some information/data to back up that statement?

Looks pretty, the link failed for me - server unavailable. probably temporary.


Depends on how you define OK. By using the cabinet you limit your sub placement options. But that may be OK. As long as the cabinet does not vibrate it will probably be OK.


Again, depends on how you define OK. Normally you would want left and right speakers to the left and right of the screen. Removing the door and replacing it with speaker cloth would likely help.

I'd also be concerned about component cooling - does it have a way to let cool air in? I'm guessing it does because overall it seems like a well designed solution for somebody who wants pretty, but still better than built in TV sound. You might want to ask them.

Here's a cheaper solution. Its a yamaha tv stand with a built in 7.1 soundbar and a subwoofer built in so that its virtually invisible. I never heard this before but it will definitely be better than putting bose speakers in that other cabinet. http://usa.yamaha.com/products/audio..._g/?mode=model It says its wide enough for a 40" tv but thats only if you don't want the tv to overhang it at all. The base of a bigger tv will fit on easily but the edges of the tv may overhang the stand on the sides.

jackbuzz may not have given the best technical explanation as to why, but it's a known fact that placing speakers inside a cabinet will alter the way they sound.

For instance, my center channel speaker is in a cabinet, and it acquired a couple of broad, nasty peaks at 205 Hz and 2500 Hz that had to be corrected with parametric equalization.
