It's a shame you can't try cabs in a gig situation, 'cos that's when you use them.
I always found the 2 Epifani 4x10's that I had to be 'muffled'. They were quite mid shy but very warm sounding, so I don't think that'd be your best choice.
The Aguilar GS cabs are similar, mid shy but warm sounding.
The Aguilar DB cabs are I think warm but with a more pronounced mid focus, and that would be my recommendation. They're also more reasonably priced.
The best guy to ask is Ken Jung on talkbass, he's tried pretty much every cab/amp combination on the planet.
Most people will only recommend what they use themselves, and if they've been duped into buying something overpriced and 'boutique' then they'll try and talk you into that.
Try experimenting with your EQ settings.
I've tried loads of cabs over the last few years. Bergs are way over priced for what they are, and have a 'sound' that if you like it then great, if not you have to try and get rid of it. The same goes for Epifani.
