Yeah, I achieved mine using a range of +2 to -12 in order avoid hitting the +10dB boost limit on the lower end of some of my channels. I do think my listening preferences are a little softer than average (probably 70dB to 75dB for music).

The second factor is the bass quality. If you are reproducing low frequencies with a reasonably smooth response curve, and with bass resonances well controlled, then bass boost is perfectly fine. If, however, your response curve is not reasonably flat, and you have excessive ringing, boost may not sound pleasurable. This may be more apparent when listening to music than when listening to LFE effects in movie content. IOW, let your ears be the judge.
Edit: Of course, this all assumes that your subs can handle the increased boost without distorting or running out of gas.
Thanks, this pretty much lines up with my experience. I had tried a +10dB boost in the past but it was too much, the bass ended up sounding bloated. I've since upgraded subwoofers to Rythmiks which are extremely clean. I've also since added maple platforms under my front speakers and subwoofers to decouple them from my carpet over concrete floor, which was definitely killing a lot of my bass before. Now after those changes and with a +14 bass boost, music sounds great and the tone of all types of guitars (acoustic, electric, bass, etc) is extremely satisfying and live-sounding. I was worried that adding so much bass to make music sound right would make moves have way too much bass, but I was surprised to hear that the movies I've tried so far actually sounded better and more realistic as well.
My REW sweeps are attached, they look decent and flat enough to me. The resulting sweeps don't actually even reach +14 on the bottom end, but I think I already have more than enough bass now.
