Sub Phasing
 

I have a Pioneer 6300 which has a normal setting for the Sub or a Rev. setting. Am I right in assuming that this reverses the polarity or phase of the Sub. By selecting the Rev setting the sound seems better. Will this harm the Sub, if not why have this setting.

This will not harm the Sub, all it does is reverse the signal the sub get.

ie the sub will push when it normally pulls and vice versa.

By doing this it can make a system sound better.

If you notice a delay in the bass notes on the sub then the phase will need changing,EG bass drum don't seem in time with the music. Normally a sub is set to positive phase, set to negative if you notice this delay. If the phase is variable shift type listen to the system at different phase settings to make your mind up on what sounds best.

Sorry But all phase does is reverse the polarity. If it is out of phase with the rest of the speakers bass will be less punchy. nothing to do with delay's

the position of the sub in the boot will also make a difference to the sound. try facing the box in different directions and placing it in different directions too...

i find also, that on your amplifier, the bass boost (if any) should be off and tweak the gain of the amp to get it to sound the way you want.
personally, i find that "bass boost" muffles the sound too much and it sounds less bassy...

Also the Loudness on the head should be off. I even take out some bass for the componants, then add more gain to the sub, you get much clearer sound:)

aye. agreed. turn your sub off, or disconect it. then turn it up as loud as you would listen to it. tune your speakers to sound how you want them. then bring the sub back into play and adjust the gain til it sounds juuuuuust right :)
