Qube QS 218 Subwoofer profesional pasiv

Subwoofer speaker system,2x18”

The QS 218 subwoofer is by design, the companion subwoofer for the QSA 210 and the QSA 112 2 way line array speaker cabinets, although it can be used to provide extended LF reinforcement for any sound system application. The QS 218 features Two 18” front facing woofers that are housed in a bass reflex cabinet handling 2800 watts of continuous power and delivering 140.5 dB SPL,to provide massive low end punch combined with high power handling and efficiency for high performance touring and permanent installation applications. The cabinet is constructed with 18 mm. (3/4”) Baltic birch plywood that is also internally braced to prevent undesired resonance at extreme sound pressure levels, and is finished with a durable scratch and scuff resistant black paint.An Optional 4 wheel kit is available to fit the QS 218, making it easily transported for touring and mobile applications.Configuration Bass Reflex
