Hello... the time has come to let go this amazing cab. I owned it for one year, give or take, but only used it at low volumes to test instruments. It was originally built for the Kalium Strings booth at the 2016 NAMM by Duke Lejeune (Audiokinesis USA) and has been designed to go ultra-low (down flat to 23hz or so). http://www.audiokinesis.com - these cabs are all the rage on Talkbass... and for a reason! It's more or less the same dimensions of the SWR Big Ben, maybe a bit taller, but
