Probably no one has responded because

a) your question is confusing--what is meant by "high power preamp?" Preamps may have a lot of drive (gain) but seldom much power--power is the amp's job

b) your question is very vague. Perhaps you mean something like "what is the best preamp stage for a subwoofer?"

A band pass filter ?

Hey there

How about a BP filter ?

I can help you design one using opamps if you want.

What gain do you need ?

Or perhaps just a LP filter

Maby you can solve it using a simpel LP filter
