My recommendation
Well, the Bose are basically my introduction into home theater audio. They are by no means a final solution. Yes, I will definitely be getting rid of them. I think my youngest brother could use them in his dorm, once I get this new system in line.
The budget I am working with isn't outrageous or anything. I'm trying to stay within the $10,000 to $12,000 range.
Also, someone made a suggestion for four subs, and that is definitely something I'd like to try to do. I didn't realize you could have four. I was worried I could get the two I wanted! If I can make four fit within my budget, I would love to go that route.
I'm obviously new to this, so let me thank you guys for the awesome information you've provided so far. I've already learned a lot. I'm definitely taking notes here.
As soon as I get the final list together, I'll post it for critique.
Please keep the information and suggestions coming. I really can't thank you guys enough for sharing your knowledge!
So now, let's change the criteria to a 7.4 system, instead of a 7.2!
Okay now some more reasonable ideas. Josetenmeat has already given some very good advice.
A square room is probably the worst shape fro good acoustices that is the reason for acoustic treatments.
Three front towers is a great idea. The fronts and center are you most important and the center should match the fronts a close as possible to maintain timbre (semaless) front sound. Obviously if you have three identical speakers the will match perfectly.
The surrounds are not as important IMHO, but true fanatics will tell you to have seven identical speakers.
As far as receiver or AVR (Audio Video Receiver) out of your budget you should spend about 1/3 on AVR and 2/3 on speakers. Your best factor in sound quality comes from the speakers.
Now Subwoofer, even for a room your size, I think 4 is an overkill. You could put in two SVS PB13- Ultras $1,599 each or two JBL Audio 113a FATHOMs for $3,600 each and have great subwoofer sound. If you have multiple subs , it is best if the subs are the same.
I personally like the Definitive Technology speakers ( even though they may be too Inexpensive fro you budget $10-$12 K is a very nice budget assuming you are not also including audio stands/furntiure , TVs, BD players). Two Def Tech BP7000SC towers at $2,749 each and a CLR3000 center for $1099 or Three BP7000SC.
For surrounds the four Def Tech BVPX speakers at $699 each.
I have a Marantz SR8002 AVR and it would work very well in your nevironment. It rertails for $1999.99
There are also good yamaha, Denon, Pineer Elite and Obnkyo choices. You can also go separate pre-pros ( pre processor and switching) and amps.
get cable and connectors from Monoprice or bluejeancables ( don't get monster)
