Product Description

The SBX218 is a high output subwoofer system designed to support any system for RSX to ADAPTive Series products. The use of neodymium woofers with a 4in voice coil ensures the best sonic performance, meeting expectations for medium to large venues.

Engineered for both production and installation uses, SBX218 is equipped with a threaded pole mount and rugged handles, making for a perfect solution for small gigs to large concert systems. Integrated runners on top and sides lock subs together to resist movement due to vibration and provide a clean look. Support of ground stack operation of NTX can be accomplished with two sets of flybar locating pins providing safe operation at any splay angle.

SBX218’s hefty grill with large openings protects the woofers, resists damage, and is acoustically transparent. The ultra large port, inspired by aircraft design, eliminates port noise. EAW DYNO gets every last dB of performance out of the system in the most challenging conditions.
