Amazing sounding little speakers, I bought these speaker to replace the dash tweeters on my 2005 Jeep Liberty, of course I had do make custom fit adapters out of plastic but fitted just right. In the beginning I was just looking for OEM replacement tweeters, but were a little too pricey for a set of cheap tweeters, after I saw these on Parts Express I couldn't resist but to buy a full-range speaker pair. When they advertised these speakers as full range they weren't kidding, these speakers go really low, maybe below 30Hz. And the displacement distance is just astonishing, specially for speakers of his size. All of these without sacrificing audio quality. Great speaker all around, would recommend these for DIY projects, replacement speakers or speaker building enthusiasts.
