Hello everybody. Love this site, btw. I just spent an hour looking for something similar enough to my situation. No luck, so here goes.
gawd... I just looked at this and it is waaaay too long ...
I have an "entertainment center" that I hope to install in-wall speakers into. I found a guy in Australia that used the Polk Audio LC265i speakers in a proscenium and he says it worked very well for him. I'm looking at the LC65i, but it could be the 265i as well. I don't think it matters for my questions.
The speakers are Polk Audio LC65i http://www.polkaudio.com/homeaudio/p.../inwall/lci65/
I'm going with this because of the Tweeter level switch and the wall distance toggle switch, two features that I believe (hope?) will overcome some of the problems with in-cabinet speakers.
There is an enclousre that can be purchased but it is very expensive ($250) and would not fit anyway http://www.polkaudio.com/education/t...icle.php?id=29
The volume of this enclosure is 1.0 cu ft. As you can see from the picture, being an in-wall device it is designed to fit between 16" studs and only as deep as a 2x4, so it is long and shallow. I can't use those dimensions, and, like the Aussie, plan to build my own. He says it's OK as long as the volume is correct.
Now, to the cabinet where this will be placed: Dimensions are 17" x 20" x 32" for each speaker's "cubicle". The EC is attached to the wall, and on the other side of that wall is a bedroom. (Nice, huh? I didn't design the house ... only bought it). TV viewing currently bothers anybody sleeping in the BR.
Here is what I hope to do:
Mostly I need to know:
I know it would be better not to have in-wall speakers, so needn't bother telling me ... unless, that is, you know of a product that makes my wife willing to accept speakers that can actually be seen.

Here is what I hope to do:
- Put sound attenuation materials on the back wall of every part of the EC. The back is wood, so I am thinking maybe just MDF.
- Put sound attenuation materials on the other side (the bedroom wall.) Thinking just another layer of sheetrock with green glue, soundrite, or maybe the soundchannel product.
- Build extra sound attenuation into the cubicles where the speakers go ... sort of a "box in a box" effect. This will is where I need help.
- Build my own enclosures for the speakers to the specs as shown by Polk (1.0 cu ft.) Looking at MDF, of couse but need some help.
Mostly I need to know:
- If anybody has built speaker enclosures for these Polk in-walls. and if not
- Do the dimensions matter if the volume is correct (1.0 cu ft) keeping in mind that apparent down firing Power Port?
- Can you tell if I need to have baffle(s) or ports in the enclosure? The info on the speakers says they have Power Ports, and the diagram associated seems to show the port aiming downward. With the length of the Polk enclosure and the shortness of what mine will have to be, I'm concerned that the benefit of this Power Port will be lost in some way.
- What else I should do to make the enclousures work.
- Is there a link or a "how to" already posted or in existence that I should look at?
- Any suggestions about dealing with the void in the cabinet between the speaker enclosure and the cubicle walls? Best treatments, best materials, fillers, etc.
I know it would be better not to have in-wall speakers, so needn't bother telling me ... unless, that is, you know of a product that makes my wife willing to accept speakers that can actually be seen.
