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 driver.

At the heart of the ASX is a unique, patented 21” 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® horn 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 2 x 18” 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.
