fried model h
The Fried Model H speaker system was sold in the 1978 timeframe as both a kit and assembled system. Designed by Irving "Bud" Fried, it was billed as the first satellite-subwoofer system. The satellites consisted of a KEF T27 tweeter and B110 bextrene cone midrange (the same drivers used in the LS3/5a speaker of the same vintage) in a sealed cabinet. The woofer consisted of a single cabinet housing two separate transmission lines driven by a KEF B200 SP1022 bextrene cone woofer as both a kit and assembled system. There was no crossover in any of the cabinets, instead, all crossover components were housed in an aluminum chassis seen atop the woofer in the photo above.
There is a great deal more information on the second version of this system, the Model H/2, and its component parts, the B/2 satellite and T subwoofer on my B/2 webpage, click here.

The cabinets undergoing rebuilding. The satellites were completely rebuilt with new boxes, and the woofer system was reglued, resealed, refinished and transmission lines restuffed. Note the woofer cabinet is upside down in this photo, and on the right side you can see an access door I added (one at each end) to stuff the cabinets.

I added a custom aluminum name tag to the rear of the cabinet to label the connections for tweeter and woofer. The labels are from Burton (very helpful) at https://www.ebay.com/str/audiotagsiowa
