The AeroTech (AT) amps, combos and cabinets series by GR Bass are stupidly light.
Why not opting for one their 12 inches Cube combos rated at 350, 500 or 800 Watts, all only weighting only 9.5 kilos (AT)...
Or even their standard Cube 800 weighting 13 kilos, cheaper and not heavy at all.
Check our @Dood trying the Cube 800 :
Ed Friedland is using their 2x8 AT (AT208 in 4 Ohms) cabinet coupled to a GR Bass One 350 (the Mini head is the "light" version of it) with great delight . Check it here :
It's all in your money bracket and BassDirect is selling them.
