Tuning Rel G1


I just bought REL G1 Sub-woofer, which I connected with Krell S1500 Power Amp. I am using High Level Input with Synergistic Research Tungsten cable to connect. Speakers used are B&W 802D's. I went through REL manual 4 or 5 times, and followed the directions to set it right.
Problem is I tried crossover frequency from 32HZ to 40HZ, but I cannot have a volume opened more than 6 or 7. I spoke to several people and there recommended volume level is 14 or 15. If I set the volume level on sub-woofer to 14 or 15 my apartment shakes and base is extremely high.

Any advise?

I agree with both of Mallen 123's comments. My Q150e runs at about 1/3 of the possible gain (based on the knob position) and I adjust it a little sometimes to fit whatever's playing...I stuck a "chicken head" knob on it for that express purpose.
I use a test CD for tone generation to see where my main speakers start to seriously drop off at the low end, and adjust my REL to pick up the "Bass Ball" at what seems to be the point where it meshes with the mains. "Mains Meshing" is the proper audio term I just made up, and the volume level can generally remain where it is until I need to tweak it due to a lack of or overabundance of bass. Although my main's specs allege they work down to 32hz (if nearly inaudible minus 10 db or something counts, I suppose they do), I found this to be nonsense so the sub kicks in at maybe 52-ish and is capable (according to the test CD) of making useful bass to around 23hz or so. It sounds great.
The reason I stuck a "chicken head" knob on the level pot of my REL is simply because it makes it easier to see and feel the knob for adjustment. Unless you use some sort of digital nanny circuit DSP filter, you should want to adjust this thing when bass overwhelms things or personal taste demands more bass. It's easy, and puts you in the tone driver's seat.
