zZounds Gear Experts Say...
Perfect for both small and large systems, the JBL SRX718S is a compact yet powerful 800 watt 18" subwoofer.
Overview
The JBL SRX718S subwoofer's compact design is equally at home as a small, high-performance satellite subwoofer system or as a building block for larger subwoofer arrays. The 13-ply birch enclosure is rigidly braced for solid response. A top-mounted, M20 threaded pole receptacle is used to ensure that even heavier, high-power satellite speakers can be securely mounted using the optional, adjustable SS4-BK speaker pole. Threaded insert points are provided for attachment of the optional WK-4 wheel kit.

This sub hits harder than any sub I have ever heard. It will take anything I throw at it. I currently have my amp in bridged mode and and have it 1/2 way up. This gives the sub about 1000 watts and it sounds amazing!
