My brother is doing an applied physics course and i remember talkin to him about stuff like this. It is all to confussing, when you look at exactly what happens (or atleast for me)

Originally posted by Exodus17 check your Eqs and make sure the bass isnt set at the same levels on both channels... its called destructive interference -

Or more comonly known as Phase Cancelation.
Basically what you have is that the waves in the kick from each track or going exactly opposite from each other thus cancelling each other out and all you have left are the frequencies that aren't cancelled out.
In an ideal world you would be able to solve this by reversing the polarity of one of the kicks but you would have to be able access the sound source for that.

There is also a common misconception that if your kicks are cancelling it means that you have your tracks perfectly matched. This is horse poo as it means nothing of the sort. It just means that you have the wave form matched in a particular way.

This effect can usually be sorted however by a quick adjustment on the pitch control (if you ride the pitch) or nudge on the platter if you are a deck plate molestor (and I know some of you are he he )

The other weapon you have to deal with this is your EQs as stated previously. Although you should be working to try and get your tracks matched in such a way that you don't experience this (it is possible).

Cheers

Thanks for the explanation. Yeah, I figured they weren't matched right, because if they were, it wouldn't do that. Haha, Deck Molestor, yeah...I am constantly messing with the pitch and the record...maybe its perfectionism. But I'll try to prevent myself from matching tracks like that...and if I do, I'll give the record a slight nudge to stop that, it's all in practice :-D

Thanks again!
