For more than 60 years, JBL® products have been bringing home the impact and excitement of the world’s best recording studios, movie theaters and concert venues. Now, JBL engineers are creating these world-class listening experiences in the car. Thanks to advanced technology developed in the professional arena, JBL mobile products simply sound better than the competition. High output, superb bass response, long life and smooth response are all things you can expect from any speaker that wears the JBL badge. So join enthusiasts who know audio, and don’t settle for anything but JBL in your vehicle. Bring the sound of the show on the road. Listen Loud The last thing you want to worry about is the quality of your speakers. We understand. All new JBL mobile products have to go through nearly 500 hours of environmental testing. We put them under temperatures fluctuating between –35°C and +90°C with up to 90 percent air humidity for more than 200 hours. We expose speakers to UV light for more than 150 hours to simulate a mounting location on a car’s rear deck. We even shake things up, as all of our new mobile audio products have to pass extensive vibration testing before we release them for production. We’ve made unparalleled efforts to ensure the best possible quality so that you can listen long and loud when you crank up a JBL speaker.

But it can get confusing and costly trying to put together the right subwoofer and enclosure on your own. This is where JBL makes getting great sound bass easy since with the GTO-1204BR preloaded enclosures, JBL has done all the work. The preloaded enclosures pair up a great sounding JBL subwoofer with a box that looks and performs better than they typical pre-fabricated  enclosure competitors offer. Polypropylene woofer cone - When you want to experience seriously low bass that is reproduced with detail and clarity, you need a woofer using a cone that is stiff yet lightweight. The JBL GTO-12042BR delivers an exceptional bass experience by using a 12”woofer cone made of polypropylene. Polypropylene is the perfect combination of strength and light weight for high power handling and efficiency. It can deliver the deep bass notes that rattle your ride as well as the subtle bass notes of an audiophile-quality listening experience. Large-roll rubber surrounds - To ensure high-performance, distortion-free bass for all kinds of music, a subwoofer cone needs to be strong when moving the large amounts of air that we hear as bass. One of the places where a subwoofer cone can be at its weakest and can distort is where the cone attaches to the basket. To ensure that the cone does not bend or flex at this connection, a strong material must attach the basket to the cone. This attachment is called the surround. Where other companies’ products use inferior materials, the JBL GTO-1204BR uses large-roll rubber surrounds. The roll’s size and strength provide stronger cone-edge suspension and absorb any distortion that might travel up the cone’s edge. The result: exceptional sound quality and detail. And if better sound quality alone isn’t enough, rubber is much more durable than other materials commonly used in surrounds. It will provide many, many miles of rocking out to your favorite artist. Progressive spiders - No, this isn’t the bug but the name of the corrugated woven material just under the speaker cone. This important part of a subwoofer is designed to keep the subwoofer’s voice coil moving as linearly as possible. In other words, a well-engineered spider is key to keeping control over the entire woofer cone. To ensure optimum control, the JBL GTO-1204BR uses a progressive spider design that exerts more force as the voice coil reaches its limit. With a Reference subwoofer, you will hear nothing but deep, tight, distortion-free bass even under the most extreme performance conditions. As we said . . . go ahead and turn it up! Large, two-inch (51-millimeter) voice coils - When it comes to bass in the car, you want to turn the power up. However, too much power, converted into heat, destroys speakers. The JBL GTO-1204BR uses voice coils two inches (51 millimeters) in diameter, which provide plenty of heat-dissipating surface area with high output and long durability. In fact, the GTO-1204BR can handle up to 1200 watts of peak power, far more than competitive subwoofer enclosures at the same price. And as a dual 4ohm design, the GTO-1204BR is going to pull the maximum power out of your amplifier. So go ahead and turn it up. We want you to. Not your typical black box - No boring black box here. A truly high performance mobile sound system should look the part and the GTO-1204BR delivers. It features unique, oversized protection bars for a beefy look that also protect the woofer from damage. Add proprietary terminals that accept heavy-duty speaker wires and that are designed exclusively for JBL products and you have a subwoofer system that looks as good as it sounds. *Note: Though the JBL GTO-1204BR subwoofer is pictured with a JBL amplifier on its carton, an amplifier is NOT included.
