My Activer One10 arrived this week. My rig is almost complete apart from trying different pre-amps. I currently have it running with a Sansamp BDDI mk2 and I am liking the sound with all three cabs. All 3 work together really well. Very growly. A single One10, either the Activier or a passive cab with a gnome, sounds a bit thin but I believe that's due to the hard accoustics of the room. I've used One10s live and they are fine.
The new cab however is winding up my OCD as the Activier One10 does not match the two previous cabs. The handle is on the opposite side and the new logo is .... Hmmm.
