LFE meter/subwoofer

I just bought a SPL meter. Should I turn the sub(Polk Audio PSW650) to max volume on the sub itself ? Then adjust the dB on the receiver to level everything out. Or should I set the sub to a lower volume and raise the dB lever if needed on the receiver ?

Thanks In Advance for the help.

    Do THAT.

    SPL meter perhaps? (vs LFE meter)

    Start about halfway or a little less on sub 'gain'. Tweek it from there.

    Russman is right.. start about 11 o'clock on the sub volume on the back of it. then i raise the level using the SPL meter with the receivers sub volume happy, happy, joy, joy!

    if you turn the sub all the way up on the rear of the unit. it's going to sound to boomy.. and will be to much bass in most cases.

    The S&V tune-up disc suggests setting your subwoofer level on the receiver to 0db. Then turning up the gain on the sub to the desired setting. 75db is the recomended setting for your speakers. Personally I like running the subs a little hot. Usually 2 to 3 db.

    0 at the receiver is a good starting point. The key is to avoid extremes at either end.

    Running too low (-10) will give you a higher S/N ratio, and running too high (+10) will lead to signal compression problems.

    Even running a bit on the negative side (say -3) is a good idea. That will give you some room to adjust upwards for certain DVDs that have a "conservatively mastered" LFE channel, while still avoiding signal compression problems.
