If you have ever heard of anything in the audio market you have certainly heard of JBL and when it comes to automotive subwoofers JBL brings their extensive knowledge and experience in the pro audio world to bear. The JBL GTI Series delivers clean crisp bottom end with the power you would expect from a concert level experience.
The JBL GTI Series balances a strong finessed look with a cone that screams concert. While many think that exotic materials are needed in subwoofers the paper cone, if properly designed, it can provide the kind of experience for those who want the multiple woofer experience in their vehicle.
Because of their strong heritage in the pro audio market and obsession of building products that deliver upon that heritage, the JBL GTI Series ranks as the final entry in my top five, although depending upon your desires it could be your number one.
