This is a Martin Audio SXCF118 flyable cardioid subwoofer, open-box and used only once for testing — originally purchased as a backup unit and no longer needed, in great condition with only minor cosmetic scuffs. The SXCF118 is part of Martin Audio's SX line and produces true cardioid low-end pattern control using dual independently-amplified and DSP-controlled drivers: an 18-inch front-facing driver and a 14-inch rear-facing driver, each on its own signal path with dedicated 8Ω power handling.

It delivers 43Hz–150Hz (±3dB) frequency response, down to 34Hz at -10dB, with 104dB sensitivity and 140dB peak output — serious low-end for touring and installed live sound applications where you need directional bass control to keep low frequencies off the stage or out of unwanted areas. Construction is multi-laminate birch ply with a textured black polyurea finish and perforated steel grilles, and it includes integral flying hardware compatible with Martin Audio's WPSGRIDT rigging frame, so it can be ground-stacked or flown as needed.

Includes the factory soft cover (a $520 accessory on its own) and integrated wheels for easy transport. Pairs with Martin Audio's iK41 four-channel Class D amplifier (6,000W) for full DSP-controlled cardioid operation.
