Ok read above. If you are talking about a pure sinewave generated tone, then yes it`ll be fine alone.
Bot most people will probably use multi oscillator synths, I would have though, and phasing sine wave based sounds can cause all sorts of problems.

And I thought I was a nerd.

Another way to generate a bass drone in a more techno type way, is to take a a bunch of low end percussion (toms, low congas or something), build a bunch of really downtuned percussion loops with them.
Cut all the top.
Maybe a little bass saturation too
compress the tits out of it
sidechain it to the kick.

Gives you that nice, but cliche, techno rumble under the kick, but with a more interestingly textural edge than just sinwave based sounds.
