The SRX718S 18″ 3200W Front-Firing Subwoofer from JBL is a compact subwoofer that delivers powerful bass performance, ideal for low-frequency support alongside full-range speakers, or as part of a subwoofer array. The sub has a strong 13-ply birch enclosure that is internally braced for durability and exceptional sonic performance. The 18″ 2268H Differential Drive woofer provides an extended low frequency range as low as 31Hz. A large port helps to extend low frequency response while reducing compression and turbulence.

The subwoofer has a peak power rating of 3200W to provide a powerful bass performance with very low distortion. Integrated handles provide convenient transportation, and threaded insert points on the bottom allow you to attach an optional wheel kit (sold separately) for additional mobility. A 20mm threaded pole socket on the top panel allows you to securely mount a satellite speaker on top of the subwoofer.
