Biamp Systems, Ltd. S-Series Dual 18" Subwoofer S-218S

The S-218S is a professional subwoofer designed to complement and extend the low frequency output of any SONUS full- range loudspeaker. Solidly constructed to ensure an accu- rate acoustic response that is uncolored by enclosure resonance, the rugged design of the S-218S handles the rigors of the road with ease. The unit is characterized by a deep, powerful and compelling low frequency response that does not sacrifice speed of attack. The result is a rapid, punchy sonic signature coupled with sustained drive, enabling the 218S to easily handle most any musical challenge or special effects requirement. Its high power and low distortion output provide accuracy and precision for musical styles including reggae, house, dance, ska, rock, metal and even dramatic classical productions. The S-218S employs internal DYNA- TECHTM protection circuitry. Using only the power from the amplifier, DYNA-TECH actively prevents driver damage, even under severely abusive operating conditions. Equipped with threaded rigging fittings, Ergo-Grip transport handles, integrated casters, and a stand receptacle that extends to the bottom of the enclosure for extra stability, the S-218S easily meets the demanding requirements of rental companies, touring musicians, Mobile DJs and other professional users.
