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.

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.
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?
BASS...it's BASS. Thank you.
Bass. Mmmm, making me hungry!
I dropped the Crossover from 35 to 25 and then even to 20 hz and started to increase it little by little. At 20 to 25 Hz I had to increase the volume from 6 to 9 but after 25 I had to go back to 6 otherwise the bass was too high. I also spoke to my dealer who sold me the subwoofer, his was same as I stated in my conclusion. Also last week I had Audio Professional to tune my system for room correction.
Conclusion: As everybody on the form said, volume number does not matter. Adjust it where it sounds right. Right now my sub is still set for volume number 6 and crossover of 40HZ. At 40 Hz sound stage does improve as compared to at 25Hz. There are some songs which have more bass than the others but overall the result is pretty good.
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.

This is the point where the sub adds to what your speakers can do. IMO this is also the perfect spot to make sure your phase/timing is correct (neither leading or lagging the main speakers).

Yes the sub is adding to the soundstage because it is crossing into the frequency range your main speakers already do. You have found some tracks with bass that seems too much because you are adding is there.

That said as my speakers are breaking in the bass is getting a lot deeper. My speakers are rated 40hz to 50khz. I initially I had my sub set to 36hz. Sounded pretty good until the lows opened and tightened up. With certain songs the bass is too heavy. So I have since went back on the crossover setting to 28hz just so I am only adding what the speakers can't do. Whats pretty amazing is I only have about a dozen songs where I can hear when the sub kicks in.
Just my opinion and my preference. Glad you have it setup they way you like it because in the end that's all that matters. So if you ever decide you too much bass for certain songs you can always re-adjust back.
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.
