More details:

The frequency range and crossover of the TOURMAX SX-SUB18 and SX-SUB15 have been specifically tailored to provide smooth, low-end sound production in the 35Hz-200Hz range. When combined with your two- and three-way speaker systems, your kick drum will thump, your bass guitar will rumble, and your beats will insite dance-frenzy masses to get their groove on. But that's not the only reason to add a SXSUB18 or SX-SUB15 to your gigging rig. Having a sub's big low-end response often means that you can run your PA at a lower volume level while still retaining a large, full sound.

The TOURMAX SX-SUB18 and SXS-SUB15 are passive subwoofer systems offering a massive 18" LF driver and large 15" LF driver respectively. They're rated at 400 watts continuous and 1600 watts peak and feature a 3" voice coil, two parallel Speakon NL4 jacks for input and thru (passive crossover), and are housed in rugged, compact, 18mm Birch ply cabinets with durable metal handles. When you're ready to extend the frequency range of your live performance reinforcement, TOURMAX subwoofers are the effective, economical sound choice.
