Blown speaker!!! Pickup only These are great cabinets, I have 2 now so I'm getting rid of the broken one. The D115XLT is a tuned and ported professional cabinet with a fast responding 15" speaker. It offers a classic rounded tone with great detail and response, coupled with a high temperature voice coil and our Eden cast bell tweeter. The D115XLT is a professional single-speaker bass option for players looking for a little more growl.
