I have a pair of W3s with the Interphase 3-A crossover/amplifier. They perform well with my Sound Lab A3s. At least they did until I ruined a driver. I was able to access the cabinet through the bottom. After removing the screws I used a utility knife to cut through what appeared to be a silicone adhesive. I went around with the blade several times and was then able to pry it off by hand. The 10" driver is polypropylene (or similar). I've not been able to identify it. It's not a driver to strike awe in ones heart, but appeared
perfectly adequate (and preformed well). As John Marovskis died in 2011, I'm not hopeful of finding an exact match. I may have to open its mate and try to determine the driver's T-S parameters to find a similar driver. As an aside, I would expect the Janis' performance to be significantly improved by damping/bracing the cabinet's interior.
