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.

Key Features:
—Hybrid large folded horn and ported design (-3 dB @ 30 Hz)
—Single 21-inch (530mm) driver with 6-inch (150mm) voice coil driver offering 2.4-inch (60mm) peak-to-peak excursion
—Switched mode power supply with PFC (Power Factor Correction) and global mains voltage operation
—On-board DSP providing delay, EQ and filtering as well as amplifier and driver excursion limiting
—PC-based software application for parameter configuration

I found this when I was watching Jackie Brown on Netflix and they showed SRW ASX 8900 XB, I remember the logo for SRW, I worked with speakers as a hobby.

I just think this thing is f------ glorious - 152 dB is louder than a jet engine taking off.

Y'all holding bomb
