Hey there, how it's goin'?
The short answer is that I've got a total of (9) 15" speakers and (2) 10" speakers (for rear surrounds)
The long answer is...........:
Harman Kardon AVR-645 7.1 Receiver (Used as a switching device between sources)
XBox 360 (Gaming and DVD transporter)
Dell XPS 400 with External USB 1TerraBit "RAID 1" for (two channel music storage in 'FLAC') using "Slimserver" software that wirelessly feeds SqueezeBox 3 (SB3)
Legion LSA-900 two channel pro amp (800 bridged watts for the four 15" Augie Infinite Baffle speakers)
Cheap DVD player (mainly used for CD's when I'm not using the SqueezeBox))
Cheap Plate Amp (for the two 15 'Augies') 250 watts mono
Hawthorne Audio Silver Iris 15" Coaxials Open Baffle (2) Front Mains
Hawthorne Audio Silver Iris 15" Coaxial Open Baffle (1) Center
Hawthorne Audio Silver Iris 15" Augies Open Baffle (2) Subwoofer
Hawthorne Audio Silver Iris 15" Sterling Augies Open Baffle (4) Subwoofer / Infinite Baffle (Under projection screen)
Hawthorne Audio Silver Iris 10" Coaxials Open Baffle (2) Rear Surrounds
Sanyo PLV-Z2 front projector - DIY Screen
Jolida 202a Two Channel Tube amp (remember vacuum tubes)
I've actually got another (newer photo) of what's called an "Infinite Baffle". I added a few more 15inchers and didn't have room for them. So, I took them and a few of the one's laying on the floor (wife says it looked like a garage sale

) and hide them under the projection screen. The results were not only an increase in available floor space, but a tremendous increase in low frequecy production (I can rattle things off shelves upstairs):
And with the grill cover installed:
So, that's my obsession.
