i am going to do the subwoofer crawl for my new SVS PB2000
what test tone is best to use ?
40 Hz ? a bit lower ?
thanks![]()
You definitely don't want to use a single tone for the subwoofer crawl test. All you'll find doing that are the modes at that single frequency. What you're listening for with the subwoofer crawl is the smoothest, most even response at ALL frequencies the subwoofer reproduces. As Alan said, play some bass heavy music with a wide range of bass sounds. Pick the spot where ALL the various bass notes can be heard equally well. You don't want the spot with the loudest bass... you want the spot with the smoothest bass.Bass heavy music is best, not sine waves.
If you have a mic and REW, I've had good success running the REW sweeps from 10 - 140Hz with the mic in the possible sub locations. Shows you where the smoothest FR is. Note that this may not be where it sounds best to you though, some prefer heavier bass (peaks) in different ranges.i am going to do the subwoofer crawl for my new SVS PB2000

this would be the ideal method if you have the equipment to run sweeps.If you have a mic and REW, I've had good success running the REW sweeps from 10 - 140Hz with the mic in the possible sub locations.

Are you only dealing with 1 sub?
Pink noise. Using a single frequency tone will only tell you where the sub works best for that frequency, using music only tells you where it's best for that track. Most AVRs use pink noise for the channel level adjustment test tones.what test tone is best to use ?
