I was just informed that due to, and responding to the user feedback, all the IDA-8's shipped from today will be at 1x as the default, and 2x and 3x can be ordered if desired.
I might add, that I posted in another thread of adding a 15" Velodyne to my IDA-8/B&W pairing with the current 3x and it works perfectly.
Volume on the back of the Sub is set at 100% *full" volume, and the remote read out volume is at 45db.
