A decade ago, JBL engineers introduced the 660GTi Component System. The premium system celebrated the company’s 60th anniversary by setting new standards for power handling, distortion reduction and sound quality in cars. Now the 670GTi brings uncompromising JBL performance to a new generation of car audio enthusiasts. Featuring the identical woofers, tweeters and crossover circuits as its predecessor, this reference-class component system delivers huge power-handling capability, flat response and unparalleled distortion elimination. It even simplifies installation by splitting the crossover into separate, one-channel boxes. The product of meticulous design, manufacturing and testing, the 670GTi represents everything JBL engineering stands for.
