UPDATE: I got the (2) 10" emminence? used speakers (12 ohm) for Berg 310 awhile back from a guy who'd blown one in his cab & got sent 3 replacements. Only needed one. Found out he'd used them for awhile in another 2x10. Been hanging on to them for awhile thinking i'd use them but have not done it so have been sitting in a box for quite some time. They work fine but appear to have some creasing in the cone paper about half an inch from the edge. Would be fine as backups or possibly lower volume applications. looking to sell/trade for other gear: sansamp, ???, etc. will sell for $45 a piece or both for $80..thanks.
