Speaker upgrade around 100k retail

Sonus Faber Aida

you font say how much space you gage; but, if you’ve got enough, for WAY less than  hundred large; why not get four Klipsch corner horns and two large Klipsh horns for front and rear center channels. Then add a pair of big, mean subwoofers, maybe something along the lines of the largest HSU Labs subwoofer, or if your even barely competent with basic hand tools, try the “El Pipo” from free plans and videos on the net. When I was in my DC and SFO houses, I made myself a pair of El Pipos. We had a forty-four foot long by 16 feet wide open living room and dining room open area. Even with the windows open, you could still feel the air pressure in the room puff noticeably when the bass or synth player hit a low fundamental.
