JL Audio F113v2
The JL Audio f113v2 is their Fanthom series with seal-enclosured design. It is a heavyweight subwoofer capable of filling the most demanding rooms with powerful low-frequency output and reference-class sound quality. The combination of an ultra-long throw W7 13.5-inch driver and a very powerful switching amplifier give it the kind of output normally associated with far larger subwoofer systems.
