ASX

Ultra-High Performance Active Subwoofer

The Martin Audio ASX subwoofer is a revolution in ultra-efficient, low frequency sound
reproduction – achieving the highest ever SPL from a single low frequency enclosure housing
a single drive unit.

At the heart of the ASX is a unique, patented* 21" (530mm) transducer/Class D amplifier/DSP
combination which provide double the output capability of a conventionally driven
loudspeaker driver of the same size. When incorporated into a Martin Audio Hybrid

design, the complete system can deliver an unsurpassed 152dB peak output (measured)
from a single enclosure. This is typically greater than can be achieved by two 2 x 18"
(460mm) conventionally driven, reflex subwoofers.

Additionally, the adaptive control loop technology maintains linearity up to the maximum
output level and power compression is virtually eliminated.
The dynamic, low distortion sonic signature of the ASX at full power is a revelation.
