Waterloo, ON (May 14, 2009)--The new ASX floor-mounted active installation subwoofer that will be on display at Martin Audio's demo room (#W202C) during InfoComm '09 is reportedly capable of producing one of the highest SPLs ever from a single, low-frequency enclosure housing a single drive unit, according to the company.
The ASX enclosure--(W) 46.85 x (H) 23.62 x (D) 46.85 inches--houses a patented 21-inch transducer, Class D amplifier with 8.5 kW peak power and full DSP.
When incorporated into a Martin Audio Hybrid horn design, the complete system can deliver a 152 dB peak output (measured) from a single enclosure. This is typically greater than what can be achieved by two 2 x 18-inch, conventionally driven, reflex subwoofers. It has been designed for club installations, stadiums and for special effects in theme parks.
Key features include a Hybrid large, folded horn and ported design (-3 dB @ 30 Hz); a single 21-inch (530mm)/6-inch (150mm) voice coil driver with 2.4-inch (60mm) peak-to-peak excursion; a switched mode power supply with PFC (Power Factor Correction) and global mains voltage operation; onboard DSP providing delay, EQ and filtering as well as amplifier and driver excursion limiting; and a
PC-based software application for parameter configuration.
