Klipsch KLF-30s with replacement mid and tweeter diaphragms from Bob Crites and also his crossover networks. I still have them, but they're stuck in my bedroom where they can't really sing like they should. My Legacy Audio Focus 20/20 (which I no longer have) were more refined, but not as much fun as the Klipsch. I replaced those with Harbeth Super HL5 Plus which are in another league in terms of sound quality and imaging, but not as much "fun factor".
What is the most FUN pair of speakers you've ever had and why?
Not the most expensive, not the best reviewed, not the biggest, but the most FUN. You know, that ONE that just makes you throw on some more music and keep listening, the one that makes your toes tap, your head bob, your ass move the most. The one that makes you think to yourself "damn, why doesn't everyone have a pair of these?" Let 'er rip.
