    The ports on the B-460 are on the right-hand side of the cabinet.

    I have 1 of each< dbx upstairs and b460 downstairs. I may have compared them when I got the dbx and almost remember not really close , lot of boom from the dbx. It has been too long to be sure.


    I have a spare 2245, should I put that i the dbx box ?

    Run a frequency sweep graph of both in the same room in the same location/position.

    You should my cat moving items around. He’s more like Supercat he move two B-460 with both paws.

    Move one of them downstairs slide it across the carpet and stand behind it and push into it and let it slide down one step at time.

    Get free REW of that home theatre shack and use the laptop or pc to run a few frequency sweeps of each sub in the same location/position should take no more 1 hour to do this, once you have the subs in one living room.

    Afterwards move the sub back upstairs. Tilt it upwards onto the step and push into and slide it back up the stairs and (remember to be careful).
