I'm wondering about the feasability of putting new speakers in my old Ampeg SVT 810 cab. It's a super old cab, square back, dolly, funny XLR type jack. I've heard they were low wattage, so I haven't played it loud. It doesn't buzz or anything, very well made cab. I'd like a clearer sound, more bass response, and better power handling. I'd thought of getting a new cab, but I've had no luck selling this one and it is such a well made cab I had the thought of replacing the speakers instead. Any suggestions? Looked at Eminence's web site, they have quite a range of speakers, I don't really know how to interpret all the specs. Would it be a good idea, assuming I could afford it, to put in 4 subwoofer speakers and 4 more focused on full range? The cab has 4 sealed chambers, I'd put the same type of speakers together. Alternately, money being a consideration, would I see a big improvement if I waited until I found an Eden 410 cheap enough and used those speakers ( I have 4 Eden speakers already without a cab)? One last thing... since I have 4 Eden 10's already, what would happen if I put 1 in each of the sealed compartments, leaving the other speaker opening empty? If it looks like I'd need to spend as much as a new high end cab I'll drop the idea, but then I'll be stuck with a big cab I don't really have any use for. I hope the thought of changing the speakers in this cab doesn't upset people as much as my mentioning that I had changed the pickups in my Rickenbacker.
