I have a friend who has the 8" Three-Way Speakers and they sounded great. That's what prompted me to look at the Poly-Planar 6" three-way speakers. It took me about a month of research because I was still skeptical of whether it was possible to get a full range of sounds out of such a small package but I'm here to tell you that the rock. I couldn't be any happier with my purchase. I can finally hear my speakers as I'm running the the bay at 40 mph.
