The new Martin Audio ASX is a floor-mounted active installation subwoofer capable of producing extremely high sound pressure levels from a single low-frequency enclosure housing a single drive unit.
The ASX subwoofer, particularly recommended for premium club installations, stadiums, and special effects applications at theme parks, will be on display at the Martin Audio demo room (#W202C) and booth (#6501) at the upcoming 2009 InfoComm show in Orlando.
The enclosure of the ASX measures (W) 46.85 in x (H) 23.62 in x (D) 46.85 in, and it houses a patented 21-inch transducer, Class D amplifier with 8.5 kW peak power, and full DSP. Combining the transducer, amplifier, and DSP considerably increases output capability in comparison to a conventionally driven loudspeaker driver of the same size.
When incorporated into a Martin Audio Hybrid horn design, the complete system is rated to deliver 152 dB peak output (measured) from a single enclosure. In addition, Martin Audio’s adaptive control loop technology maintains linearity up to the maximum output level and power compression is virtually eliminated.
