The Fried Model T was a dual transmission line subwoofer, using a pair of 10" Dalesford woofers. It included a crossover to roll off high frequencies to the woofer as well as a set of direct inputs for use with an electronic crossover. It also included a simple first order passive crossover to roll off the low frequencies in any associated satellite.
The Model T was sold both separately and as the woofer portion of the Model H/2 system, which also included the Model B/2 satellites, complete system shown below. Lots more info on the H/2 and Model B/2 is here.
