Firs a few replies to you guys...
@Nestor:
I have very limited and unusual space, 10" deep, 20" wide and about 30" of hight so the best usage of that space would be to put as big a driver as I can in a sealed box and hope I can drive it to the levels I need.
@jcl:
This time around I'm not renting the apartment, I'm buying so I'm not limited to any owner is allowing me to do, but I just don't have enough $$$ left for the speakers I want. Down the line, in 4-5 years I plan to upgrade but at the moment that's all I can afford
About in wall/in ceiling Vs regular speakers, if it were up to the Mrs, there would be no home theater in this house so it's either in ceiling/in wall/in cabinet/in something or nothing so this will have to do.
Got it about the subs and DIY, I'll post on the correct forum.
@zieglj01:
No challenge at all, the contractor made a double ceiling with 6" mounting depth available and pre installed wires in the walls and ceiling.
Just one neighbor and I don't know him yet, hope it will be OK. Going to do it anyway...
About speaker choices, some options I found:
1. JBL-L228C, they are on sale now for $108 on amazon.
2. Emotiva UAC 8.2 on sale now for $140. with pivoting tweeters.
3. Martin Logan Helos 10 on sale from audioholics also with pivoting tweeters on sale for $149.
