Just got two of these Epi UL-310 cabs from a local TB'er and while I LOVE having two, it's just overkill for me; one is more than enough. I also have too many cabs right now and gotta make some room!
This UL310 is basically new...never been gigged, just sat at home (excuse the pic quality...had to use flash). Still has the unregistered warranty card hangtag on it! I don't know if you can register it since you'll be owner #3, but it never hurts to try. Specs on the cab are here: http://www.epifani.com/products/concert310.php
Only 47lbs...I can easily carry one UL310 in each hand. Tone is so sweet and they're super efficent cabs (I got plenty of volume just using my AI Clarus Series III (400W @ 4 Ohms). The cab is 5.3 Ohm, but just think of it as a 4 Ohm cab. Selling for $775 shipped in the continental US.
