CSX218 | Dual-driver Subwoofer

This is now a legacy product.
We recommend SX218

The CSX218 achieves the ultimate in subwoofer performance for the most prestigious CDD Series applications – delivering very high output levels and superb transient performance with minimal distortion. With an operating range of 35Hz-150Hz ± 3dB, it houses dual 18” long-excursion (460mm)/4” (100mm) voice coil drivers with water-resistant cones and triple roll surrounds. Each driver is rated to handle 1000 watts AES, and has a magnet structure and suspension engineered for maximum linear excursion.
