[AleroB888]

This is the latest incarnation of a system I have used since about 1978. The classic Heil Amt-1 midrange/tweeter in a 2-way 10 inch woofer stereo pair, and a JBL 2215 subwoofer.

The sub can be slot loaded, corner loaded, used as a coffee (beer) table, or like here, with a video monitor. The box is 6 cu.ft., double 3/4 particle board, finished plywood top. The monitor can be slid forward for better viewing, or farther back for critical listening.



Most recent prototype crossover network, mounted inside the box when finished:



The main stereo channels have a 3 cu. ft. box divided into 3 interconnected sections, one driven 10 in. woof, and (so far) 2 passive cones. Once the tuning has been settled on, new enclosures are to be built.





Hey look, it's what's-her-face on SNL



I'm almost but not quite satisfied with the sound quality of the system. The challenge has always been to find woofers that are smooth enough yet efficient enough to keep up with these tweets, and matching dispersion patterns. But even as is, I've heard nothing in their size that produces as believable a rock and roll sound, and they do quite well on country and jazz, too. I'll try to get in some pics of the test equipment (mostly old school) and process that goes into the design.
