Product overview

The SX418 is a powerful single 18" subwoofer with a power of 700 Watt RMS. The sensitivity is rated at 100 dB, and it is capable of a stunning maximum sound pressure level of 129 dB, still with an extremely flat frequency response between 35 – 250 Hz. The connections are made with Neutrik Speakon connectors, and there’s the possibility to link more SX418’s to each other.

The impressive combination of punch, very low frequency reproduction and accuracy is achieved by the 18” high-excursion driver with his very powerful four-piece magnet.

Because of the high pressures which occur inside the subwoofer cabinet, a complete reinforcement frame is mounted inside the cabinet.
