TC265 install and system upgrade

Tamrac

Hello,
I've been a Polk fan for over 25 years and have had my Monitor 10B's for most of that time. They have served me well as my mains in my 5.1 system, but I'm in the process of converting my home theater to go along with a new 50" flat screen. I've just installed a pair of TC265i (in-wall) as my mains and have a couple of questions.

1. Since my only access to the wall interior is through the speaker hole, are their any good in-wall enclosures I should use, or will a loose fill of fiberglass insullation be sufficent?
2. I was going to use another TC265i as a center, but the wall studs squashed that idea. Will the new LCi-C due out next month be a good voice match?

Current setup

• Yamaha RX-V1700
• Pair TC265i - mains
• CS150 - center (to be upgraded w/ LCi-C?)
• Pair M5 surrounds (to be upgraded w/ LC65fx or TC60i)
• PSW150 sub

Tamrac, you probably won't get much in the way of help for inwalls around here. There just aren't many people that have them. I recently was looking at an inwall system, really mostly for surrounds, but just couldn't get alot of information on them. Good luck, please let us know how it works out for you.

PS, you could always cut the stud and box it out. That would probably be your best bet, but would just cost you a bit for drywall repair.... which would STILL be lots cheaper than buying an LCiC....

First off enclosures would require more than the speaker hole. Are you handy when it comes to doing dry-wall? Loose insulation fill will just get down inside the speaker, unless you protect that from happening. Having a foam padding directly behind the speaker would help. I am in the process of building my house now and plan on using inwalls in the vaulted ceiling (7.1 system). I am going to build the enclosures myself and then use the foam padding I refered to. When I say enclosure it is nothing more then a 2x4 in between the exsisting 16 inch wide studs spaced appx 26-28 inches apart then seal the joints, cut my holes in the drywall and drop the speakers in. After that I plan on cutting plywood same appx size (16x26 or 28) put padding on it and sealing and **** it down over the top of speaker from inside the attic. In my case it will be easy beacuse I have access to everything. Your case will require some work. Hope this helps.

Well, after a little searching I came across these Speakercraft Acoustacells.

Easy installation through the speakerhole. More than just foam, these things are heavy. Fit nicely between the studs and provided a nice sound chamber for the TC265i's (they are made for a variety of Speakercraft speakers, of which the AIMLCR sieres is similar in size and specs to the Polks).
Very noticable increase in Bass response:D Speakers sound a lot fuller and richer. Highly recommend these to anyone looking to do an in-wall set-up.
They retail for about $100/ea., however I came across a few on eBay which I picked up 3 for $20/ea plus about $25 shipping (like I said they are heavy).
