getting a deep bass kick

[ekord123]

Greetings, I'm new to live and still understanding some concepts.Right now I'm trying to get a deep bass kick tone (i.e. the kind you hear in electronic music, and hip hop). here are a couple of key concepts that I kind of get, but I could use some filling in:

sampling- is it possible to start out with a pretty normal kick drum and turn it into more of what I'm looking for? live 8 has quit a few kick samples, I'm guessing that I just load them into impulse (don't have operator) and edit them, but from here im confused. from what I gather I need to use a low pass filter, and get it within the 50-150 hz range. If anybody could expand on this it could be very helpful.

but in general, is there anything I'm missing out on? And are there any good free or inexpensive sample libraries I can pull from (with soft synths, as well as kick samples).

Cheers

Have a look around kvr's sample forums there are tons of freeware samples there.
