I came home and today I fired up Pink Floyd and feel pretty damn good about my system. I assume that you saw the PBN system with six JBL 18"s, two JBL 12"s, and an AMT in the big ballroom? Mine is similar but with just one JBL 18" (2241H), one JBL 10" (2251J), and a modified ESS Great Heil AMT per side. Does one really need twelve 18" woofers in a living room? These were designed in the room for the room and may/probably even image better than the PBN system.
I didn’t hear anything that imaged any better than these though some certainly did a great job. But I’m betting that few could attain the realistic volumes of a live rock concert at undistorted levels.
BTW, my speakers cost <$1,500 to make with used drivers but new crossover components.
This is an SACD played on an OPPO95 through a Yamaha RX-Z9 RECEIVER in Pure Direct mode. Video was recorded on a Nikon D750 DSLR using the internal mic. There is no eq or room correction, either electronic or physical, being used and the room is ~5,000 cu ft so of course you hear the room in the recording.
BTW, we are in the North Tustin area and members are welcome to come by and hear for themselves.
