These are ripole subwoofers by Jazzman:
Looking for a pairing for my ripole subwoofers, I've been really inspired recently by these coaxial open baffle tractrix/JMLC horns. They are open on the back and the midrange/bass drivers are horn loaded in some exponential way. They’re are mechanically time aligned to the compression driver thats attached to the back with the other drivers and protrudes into the vertical horns. These below are inspired by the BD (Bert Doppenberg) Designs Orelo and Klangfilm speaker. 6moons
