I'd probably say that these 1967 vintage Bozak Speakers are about the largest "bookshelf" speakers i've ever owned. They contain two 12 inch woofers, an 8 inch midrange and a vertical line array of 8 tweeters, in each cab. They even made them in "left" and "right" side mirror image of each other.
Located in the "southern command post" in western North Carolina.
What is driving these speakers, you may well ask...
This can probably claim to be the world's most compact DIY-35 rev D amplifier. Chassis is 9" X 10" X 1.5". Power trannie is Hammond 270FX, OPTs are Triode Electronics TF-110-48-ULs.
The only items below the chassis are the AC power primary side (fuse, switches, a neon light, some wiring, the volume pot, and the input jacks. and an all-important one watt blue "Luxeon" LED powered off the otherwise unused 5VAC winding, just for the cool blue glow and to act as a second pilot light.
I'll bring one of the "big gun" amps along, my next trip down there...
