Massive audio SUMMO64XL - 6.5" 150 Watts RMS DUAL 4 Ohm, 1.5" V.C. Subwoofer

Product details
Tight space shouldn’t mean you need to sacrifice power handling and bass. Our SUMMOXL line is all about premium bass output, with balanced response. We want you to get a lot of performance from the low notes in your music. Just because you do not have loads of space for a huge cone subwoofer, does not mean you have to settle for weak bass performance. The SUMMO64XL addresses that head on.
At Massive Audio, we aim to make unique designs to solve different challenges in audio. For example, we approached the 10” & 12” shallow mount subwoofer market with the very cool UFO series. But what if you needed even more extreme space savings with a smaller sub, while still having great bass in your ride? Our all new Massive Audio SUMMO64XL is a hefty approach to that solution.
The SUMMO64XL shares vital performance parts from the bigger models in the SUMMOXL line, such as the Kevlar Fiber enhanced non-pressed paper cone and OFC direct leads. In addition, a 4-layer, high temperature voice coil, fiberglass woven dust cap, a high roll surround, and triple black poly cotton spiders with a mirror image layout. All of the DNA from the SUMMOXL line, mixed with the innovative motor design, adds up to a very strong approach to a compact subwoofer that can keep up with the big boys.
Our Massive Audio SUMMO64XL is a high-performance car subwoofer that delivers powerful and punchy bass. With its dual 4-ohm voice coils, the SUMMO64XL allows for flexible wiring options and compatibility with a wide range of amplifier setups. With its oversized 110 oz. ferrite magnet and high-temperature aluminum voice coil ensure reliable performance, even under demanding conditions. The specially designed non-press paper cone and reinforced steel basket provide a strong and responsive foundation for the subwoofer's impressive sound quality. Whether you're a basshead or simply looking to add some depth to your car audio system, the Massive Audio SUMMO64XL is an excellent choice.
