I hope this isn't old news....check it out: http://www.wmcworld.com/inv.asp?d=guitars&sd=bassamps&b=Ampeg&n=716 A 38 pound 2x12 on wheels, how about that. Has anybody seen or played through one? * Component: 2x12" * Voice Coil: 2" * Magnet Weight: 4 lbs. * Component: compression driver P.E.I. Composite diaphragm * Voice Coil: 1" * Magnet Weight:4.7oz * RMS Power Handling: 400 Watts * Program Handling: 600 Watts * Frequency Response: 40Hz - 20kHz * Nominal Impedance: 4 ohm * Crossover Frequency: 3.5kHz * SPL: 93dB 1w/1m * Xover Protection: High positive current coefficient resistor * Weight: 38 pounds Now, if they'd introduce a 4x10 to the portabass line I'd grab it in a second. It would probably only weigh 50 pounds or so.
