The SP® 218 subwoofer is designed for large systems and works perfectly with the Peavey SP® line of enclosures. The SP® 218 uses two custom-designed large excursion 18" Pro Rider® Black Widow® woofers that can produce incredible deep bass with very low distortion handling up to 4800 watts of peak power. If your looking for amazing lows and thunderous bottom end to accompany your SP® enclosures, this dual 18 inch 4 ohm cabinet will deliver the goods sonically. The solid cabinetry construction of birch ply is carpet-covered and has an extra heavy-duty grille for ruggedness.
