I need some advice.

A friend and I have built a subwoofer system and are having trouble
determining the best type of crossover to use.  It should definitely
have a crossover point below 150 Hz and preferably have at least a 12
dB/decade rolloff.  It should also have a power handling capability of
at least 200 Watts if it is a passive design.  We have looked for
articles and advice for a while and I have decided to give the resources
of this bboard a chance.

We would prefer an active crossover, but if we get a good passive
design, it is not out of the question.  If anyone has any schematics or
suggestions, please contact me.

Thanks
