100W, 2x5" Piranha speakers. These dedicated drivers were specifically designed for the briefcase, driven by a high current 100-watt (RMS) amplifier housed in rigid metal chassis.
Can be used with rechargeable 12v 7amp battery - essentially a motorcycle battery; these usually cost around £20 new - so it's also ideal for use when busking or on camping trips & similar. If you don't fancy the battery option, there's a cable that comes with it to allow you to run the combo from your car's cigarette lighter socket.
Weight: 28lb (excl. motorcycle battery!)
Dimensions: 6.5" x 14.5" x 15.75"
Inputs: Active/Passive
Others: Compressor/limiter, 5-Band EQ, Headphone out, Balanced-line out, Pre-amp XLR out, Extension-speaker out
Words like "pristine" and "immaculate" spring to mind. In perfect working order, and I think I even have the original slip case in storage somewhere.
Shipping is at least possible, but the weight would make that both undesirable and expensive. Still, "never say never" ...
