JBL Concert Series 421F 4" 2-Way Speakers

These are the JBL Concert Series car speakers. You can get the JBL Concert Series speakers in all of the common car speaker size. Four inch, five and a quarters, 4 x 6 and 6 x 8 2-ways, or six and a half inch 2-way, 3-way, and two-way component systems, and six by nine three ways. And most are available with or without grilles JBL knows a lot about making bands sound amazing live in concert, and they can certainly bring some of that great sound into your ride. The edge-driven dome tweeters sound loud, clear and musical, and the 3-ways even have a dome supertweeter for detail and clarity that is above and beyond what you might expect for speakers at such a reasonable price.
