One of my prized possessions must go. I'm just too old to be hauling this, and my Cerwin Vega B-36 MF around anymore. I bought this a long time ago, with the low power handling Sunn speakers. I immediately removed them, and installed some Eminence 450 watt 8 ohm drivers. I'm not sure which model they are, but they weren't cheap, they might be Delta LF's, but cannot say for certain. So, it's a 4 ohm, 900 watt RMS cabinet now. I have literally, in the last 20 years, used this cabinet maybe a half dozen times. Mostly outdoor gigs. It's been sitting in my living room all this time, waiting for a festival gig..that still hasn't happened. In pretty good shape for its age, and works fine, last I tested it.
