If you were gonna power up 2 sets of SRS 1.2s, what kind of amplification equipment do you think is best and why ?
Please keep total cost under 12k, I am looking for GREAT Audio bargains that can effortlessly drive 1.2s to their maximum potential.

2. How loud do you like to listen?
"Maximum potential" will be somewhere in excess of a thousand QUALITY watts into a nominal 6 ohm load (and we all know that the actual impedance varies with frequency response, and in the case of the SDAs, with the signal difference between channels--so you'll want an amp that can handle 3--4 ohm loads with grace and ease.) First Guess: In anything like a "normal" listening room, your ear drums will touch in the middle of your head with that much volume.
Mind you, I got into deep doo-doo awhile back for suggesting that watts required was related to volume level. -

I do not own a house yet, I am working overseas as a techical adviser to the US Army, saving up for my house that I will buy in a year.
I know it will be at least a 3000 sq ft home with a dedicated room of at least 20x20 ft. I may end up going the new construction route.
Thanks for all of your great equipment recommendations - I am researching alot in my down time here in Afghanistan. -
You do not want a square room. A ratio of 2 to 1 is ideal.Political Correctness'.........defined

:eek::eek::eek: I want that soooo bad. BTW did he mention look no further!!! The kW 500 is a match made in heaven for the big SDAs. -
Two times as long as it is wide??? Also very bad for standing waves. For instance, any standing wave that is reinforced at 10 feet...is also reinforced at 20, 30, 40 feet. Any standing wave at 8 feet is reinforced at 16, 24, 32, etc.You do not want a square room. A ratio of 2 to 1 is ideal.
Ideally, the length, width, and height are NOT multiples/factors of each other. There will still be standing waves, but at least they aren't all at the same frequencies bouncing left and right, top and bottom, and forward and back.
I've heard of computer programs where you input the dimensions of a room, and speaker locations--and it plots the standing waves; gives you an output of what frequencies are reinforced, and where in the room the peaks and nulls are. A simple version of this program, written in BASIC, was included in some audio magazine (Audio, probably) back in the early nineties. Seems to me that it didn't work as written, and the next month they published the corrected program.
Once you get suitable dimensions in your room, you can work on Live End--Dead End (LEDE) principles (or not--not everyone agrees with the theory); and of course spend zillions of dollars on pillows and traps and such. All very worthwhile. In fact, the pillows and traps can mellow out the standing waves in a BAD room. They're arguably more useful the worse the room itself is.

If you were going to design a room, the following dimensions would be the best to control resonances within the room:
1 (height) x 1.61 (width) x 2.6 (length).
Do some research on the Golden Rectangle or Golden Section. Those Greeks were some smart fellas... -

Absolutely. This is the ideal ratio for recording studios as well.This post SWMBO approved.
