I think the BFD will make a big difference. Right now you probably have a huge freakin' peak around 44 Hz, and probably smaller ones at 88 and 132 (being 2x and 3x). If you took down the peaks (esp. 44 and 88 Hz) you should be able to turn up the level almost the same # of dB, at which point you should start to get more bass you can "feel".

I'm guessing you will also start to hear more difference between the 350 and your JBL sub with the BFD. I don't think the room is letting you hear much below 35-40 Hz without making the higher freqs too loud -- the BFD will help.

Do check around for vibrating house parts though; when I was running the PSB 6i (comparable to the EP350) all of the "sub noise" and "port noise" I heard turned out to be "heating duct noise" up in the ceiling.

Good luck. If all else fails you could try sitting on the sub
