This an Ampeg 4x10 ported cab. Nominal Impedance is 4 ohms. Program Handling is 800 Watts and RMS Handling is 400 Watts. Usable Low Frequency (-10dB) is 28hz. It has side handles, handle bar and casters. It is 6 months old and in mint condition (haven't moved it since I got it). Selling for 500$us. Ok so here's the catch. This sucker is pretty big so I don't know how the heck I would ship it (LMK if you have any ideas). But if you live in Conn, Mass, or RI I'd be happy to deliver it personnally (I live in RI) and if your in Maine, NH, Vermont or NY I'm sure we could work something out.
