Relieved the Aerotec 2x10 sounds good in the living room test. Nice clear deep sound and it's so light. I've got the 4ohm version, so I can compare it with my 2xBF one10's, also 4ohms. Mesa d800 amp. The GR bass cab seems louder than the BF's with same amp settings. The GR is also brighter as you would expect, it has a tweeter. Turns out the tweeter control is 3 position switch, not a variavble L pad as per GR's advertising. Not a problem for me, positions are "off, bright and even brighter). The first "on" position sounds good at home, we'll see when and if gigging resumes. Build quality feels good, although I suspect the plastic corners might not stand up to abuse. Digging into low B string sounds clean, theOne10 pair breaking up a bit before the GR 2x10. Overall pleased so far. Could be tempted to replace the BF's with a GR aerotec 1x12 at a later date😂
