I'd go with Eminence for a replacement speaker (and have). I like them because they have such a wide variety of speakers, and are very reliable, and their customer service is top notch. Celestions are good, but are way way over priced and overrated. There's no such thing as a "be all, end all" speaker. Everybody's tone tastes are different, and people hear things different than each other. So, what works for one person, won't work for everyone.
