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?

set it by ear for your room vs levels recommended by other people. G1 is a huge sub designed for large spaces, so 6 or 7 in an apartment might be all you can turn it up to.
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.
Different cd's have different base in each track, how do you keep up with controlling the base. Some track or cd are well balanced with base along with other instruments. But some tracks are so full of base, how someone can control it? If your sub does not have a remote how do you control the base?
If you turn it up to the point you can hear it, it's too loud. It will give you a good foundation for your audio but it isn't meant to rock the house. If you don't like it get in touch.
