JBL SRX728S Dual 18" High-Power Subwoofer, 6400W Peak Power Rating

JBL SRX728S Dual 18" High-Power Subwoofer, 6400W Peak Power Rating

The JBL SRx728S Dual 18" High-Power Subwoofer delivers powerful bass performance, ideal for low-frequency support alongside full-range speakers. The sub has a strong 13-ply birch enclosure that is internally braced for durability and exceptional sonic performance. The 18" 2268H Differential Drive woofers provide an extended low-frequency range as low as 27 Hz. A large vent helps to extend low frequency response while reducing compression and turbulence.

The subwoofer has a peak power rating of 6400 W to provide a powerful bass performance with very low distortion. Standard Speakon connectors allow you to connect the sub to a variety of speakers and sound systems. There is a recessed external switch that allows you to select contacts +/-1 or +/-2. You can also relocate an internal connector in order to drive each speaker discretely from separate amplifier channels. Integrated handles on each side of the cabinet provide convenient transportation.
