The ACV FEST series subwoofers feature proven and reliable technologies for reproducing low bass in cars.

They feature a rigid and lightweight non-pressed cellulose cone, two high-quality ferrite rings weighing a total of 100 oz, a high-temperature dual 2.5-inch voice coil, a 10-inch spider, stitched leads and spring-loaded terminals. They feature first-class assembly and 100% quality control at every level of production. The FEST F15D2 subwoofer differs from its smaller sibling, the F12D2, with a larger cone area and a significantly higher rated power of 650W, making it highly efficient and powerful. Choosing the F15D2 ensures greater bass depth and high SPL.

The ACV FEST's excellent electroacoustic performance allows it to be installed in any type of enclosure. At the same time, its price is competitive in the car audio market. Incredible durability, performance and very tight bass – just what your car needs.
