Has anybody used these for bass guitar? I'm thinking about using a pair of these either in two seperate cabinets or one cabinet. They are 8 ohm speakers. I mostly use tube amps. But I do periodically use my Aguilar TH500. I don't have a cabinet yet so I'd have to have one built. I really like the sound of my JBL d140's. I have 2-15 and 1-15 cabinets. So I'm thinking maybe a 2-12.
