The Cab that I have is the LS215 I believe. I came on this site to find more information about it but I think I'll share what I know to hopefully help out. Here is what I know about it:
-300w at 4 ohms. 1/4" inputs.
-2 GBE speakers but not sure which model. The newer LS115B has the GBE1540 and this cab is essentially the same with an extra 15" speaker. Two ports in the front also. See this page:
Discontinued Products | GENZ BENZ
This website does not list it as a discontinued model or mention any 2x15 cab at all for Genz Benz except the TAC EX-21502. That model seems to be for club use. I think it was handmade before a change in ownership when Genz Benz was in partnership with Kaman (but dont' quote me on that).
-It has an older logo which is not anywhere on my Google image search. I'll try to get a pic of it and put it up. Very 80's looking actually. The inner part of the cab is white with a steel grill. Also looks alot like the LS115B.
Bottom line is this thing is awesome. I bought it used in 2003 I think from Calliope in Burlington, VT for about $300 (steal). Tried it out with a KSD proto J which I also now own and had to buy it. I used to use a Hartke 350 watt head with it for many years and it never shook the speakers (at all). Only when I got a Fender Bassman 300 (all tube, 300watt) that I started seeing them shake. I've played tons of other cabs and this one has always given me the smooth but clear bass sound that will have you by the "you know what". Recently, I found a newer 1x15 version to use for gigs but its only because this cab is really hard to take around by yourself. Probably 50 inches tall but surprisingly light weight for a huge cab. My Impreza fits it just fine but piling other gear can be a major issue.
If you like a more vintage sound or good tight highs without any harshness, this cab is great. They are EXTREMELY rare to find so if you see one, try it out.
Lot's of stuff for sale from this guy.
