How should I set up REL G1sub woofer


I just bought Rel G1 sub woofer and I read the user manual three times, but it's not replacing someone's experience. I have B&W 802d speakers with which I am hooking it. The problem is even a little base is too much base.
If I tweak it with one song and than with another song either the base is too high or its too low. Any body with experience what is the standard crossover and how high the ever age volume should be on this sub?

Also, you need to make sure the sub is fully broken in before you start doing anything. Spiked feet would probably be a good idea, as well.
I have crossover frequency set at 40 and my volume is set for 6. Yes I am using speakon cable and power amp is class A by Krell S 1500 7 channel. Time sub is about 3 or 4 hours as I just got it. I tried raising volume to 10 or 12 but it's over powering the rest of the signal.
Trcns,

Try lowering the crossover to between 28-30Hz. You may have a 35-45Hz node in the room. See if it makes a difference. If it doesn't, then I would switch phase polarity on the sub. If that doesn't help you may need to contact REL for assistance. I have found them to be very responsive via email or phone.
My experience with setting up a REL (Storm II) is that I found that I ended up setting the crossover lower than I would have thought was necessary. In general REL recommends setting the crossover lower and raising the volume a bit. I found that combination worked best for me. With the remote control that comes with the G1 I would think this would simplify the process.
