I have a Silvertone 1333 that I really like. The tremolo is absolutely wonderful. But the speaker truly, truly sucks. I had my amp guy wire it up to where I can unplug the stock speaker and go out to an extension cab and it sounds great that way, but I'd like to find a quality replacement speaker so I can leave the cab at home. Here's the problem- the speaker's magnet is tiny because it sits directly under the chassis (see pics), so I'm not sure what I can fit in there. Ideas? Thanks!
