Well, I have now received a bunch of my AV Equipment... if only I was making progress on the room:
I purchased a Denon AVR-4520 and my projector, a JVC DLA-RS-4910 (and Chief mount, ceiling plate down-rod).
I also got my speakers... 5 Klipsch in-wall KL-7800-THX and 4 Klipsh KS-7800-THX speakers.
- the KL line is for the front LCR & 2 Rear Speakers
- the KS's are the surrounds, definitely will do one row of surrounds, and then not sure if I'll do another row of surrounds or if I'll use the other pair for "Width" speakers.
My speakers will be mounted inside my columns, inside the overall room envelope to help minimize sound escaping.
The Denon can process 9 speakers, I haven't done any reading yet on how to set up two sets of side surrounds, so I am hoping it can be done with out another amplifier.
I have the MDF to build two 'full marty' DIY sub's, but haven't even started cutting... or ordered the 18" drivers. I was considering UXL-18s, but haven't been able to get a reply from the company, so may save a little and go with Dayton Ultimax 18s. I am a bit concerned the in-walls won't have much mid-bass, and I think the UXLs are better at the higher bass frequencies, although frankly, my knowledge on all that is somewhat limited.
I have visions of grandeur in terms of making progress in my basement, and hopefully theater, over the Christmas break... although, my guess is my wife will likely squash those plans. I hope to put down ~ 1,200 square feet of engineered hardwood and 120+ square feet of tile in the 'rest' of the basement before I really do much more work in the theater. I might build the Riser, in large part because I need to build the portion of the riser 'outside' the theater before doing the rest of that work.
