- Although some people may tell you otherwise, I would say you're ok
- using a higher power amp for the woofers than for the tweeters. For
- example, use a 100 watt woofer amp which doesn't need to have very
- good sound quality at high frequencies, and a very clean-sounding
- 20 w amp for the tweeters.
