Ampeg 1540 cabinet: 4x10 sitting above a 1x15 in an 8x10 sized enclosure (minus an inch of depth). Two of the 4 10's replaces with eminence beta 10a's, which add a great punch to the cab. Sounds awesome, and is devastatingly loud/full. Tweeter removed after it blew a few years back, but the port is very effectively sealed. Can be used as two 4 ohm sections, or one 8 ohm full range cab. very good cosmetically, with only minor dings in the tolex, but nothing structurally compromising. looking for $400 in a local deal (not looking to ship this monster). I do no have photos handy at the moment, and will not be back in the northern NJ/NYC area for about two weeks. Thanks for looking!
