A friend picked up a pair of these, in pretty good condition (he says). A curiosity that I'd never heard of before! It seems to be a 15" woofer with an LE-5 glued to the pole piece, but I can't make out the picture very well. Haven't seen them myself yet.
The brochure is available:
Apparently his are without any crossover. The proper crossover seems to be the 3125, also available at
which seems to be a simplified 3120.
Anyhow, does anyone recognize these? Or know anything about them? I'm especially curious about how such a beast came about, and how long it lasted.
