now that ya gott'em home first things first...double check the your wiring to ensure no phasing issues...after you've done the "black n' red" thing I'd spend a boat load of postioning time...and if your still no happy I'm phone the company and tell 'em ya got an issue....After doin a quick scan on the net I'm no seeing any lack of base in any reviews?...and with the BAM in place there could be something wrong that that lil black box? Only the company would know....one more point...although ya cant run out and put your ear on another set you can compair...if you've got access to another pair of speakers that have been compaired (in a review lets say) or have gone head to head with (at a show) that might help when you phone the company or speak w/ current owners. For example if B & W had a model that "bass-wise" would be close go see/listen if it's in the ball park...if not you could use that for an example when calling the company....also go to any local dealers to see if they've every heard your particular model that might help...and if all fails...sell them to me for a song and start over!

good luck!
