Product Overview
The SXP118 is a compact yet powerful subwoofer designed to enhance the low-frequency performance of CDD-LIVE! full-range systems, extending the operating range down to 40Hz for impactful bass and increased headroom. Featuring a long-excursion 18” (460mm)/4” (100 mm) voice coil driver with a water-resistant cone and triple roll surround in a compact reflex enclosure, it ensures high output with minimal power compression and distortion.
