Hi all - bought a Fender BXR bass rig years ago, and the bloke I bought it from threw in an old handmade cab with a 15" speaker. The cab is quite large and bulky, but it sounds very thick and loud and although I use it at home for a prac amp I've been thinking of making up a new box that would fit easier into my car for acoustic gigs instead of my bulky/heavy 410's. Having said that after owning it for 10+ years only tonight did I unscrew it to look at the brand name, etc. The info on the back of the driver states that it is a Gauss loudspeaker model 3580, 8 ohm. No other info. Just wondering if anyone has any more info, including wattage, that could help me design a cab for it. My internet searching didn'y really yield much. I gotta admit the driver is in great nick. It must be 20 years old but looks new. Thanks in advance.
