If you want to make noise get a drum set
Studio style flush (soffit) speaker mounting - speakers are mounted into a wall with drivers flush with wall surface. Note that this is not simply an HT cabinet - all of this was custom built with extra thick MDF and heavily braced to eliminate vibration. Speaker is decoupled from framing with rubber pads and surrounded with 8 inches of pink acoustic fibreglass on all sides.
The bookshelves above are intended to absorb some lower frequencies, as is the log fire place which is 8 feet behind the listening position. More acoustic absorption is achieved by four massive GIK Tri-Traps. The audio signal that goes to the subwoofer is treated separately by a PEQ with specific notch filters to eliminate LF room modes.
The down firing ATC 15" subwoofer is driven by its on board 1000 Watt amp (positioned to the left of the main speakers). Active ATC main speakers have three separate (Class A to two thirds power) amps each for each driver: 200 Watts amp to each 12" woofer, separate 100 Watts amp to each mid range and separate 50 Watts amp to each tweeter.
Five giant Sony Megachangers are controlled at the touch of the keyboard trackball, all from the listening chair (software controlled from the Mac Mini). Each of these five Megachangers TOSLINK output is connected to a Benchmark DAC1. The DAC1 corrects for the jittery TOSLINK outputs and produces a sound quality way beyond the modest price of the combination.
All in all I try to combine convenience with a pretty high end sound.
Doug Sax of Sheffield Labs fame uses soffit mounted active ATC speakers driven by Benchmark DAC1's in his studio. I figure what is good enough for Doug Sax's "golden ears" is certainly good enough for my "tin ears"! Besides, as so much music is mastered by Doug it is nice to hear it as close as possible to the way he does when mastering.
