Martin Audio in Waterloo, Ontario, Canada introduces the PSX as a companion self-powered subwoofer for the company's DD6, XD12 and XD15 full-range loudspeaker systems. Featuring a 15-inch/4-inch voice coil, long-excursion driver in a compact reflex-ported enclosure, it houses two channels of Class-D amplification: one channel for itself and one channel to power an XD12, XD15, or up to three DD6 units.

The PSX subwoofer’s Class-D amplifier section is said to produce a total peak output of 2,400 watts, with 1,400W allocated to the 15-inch subwoofer and 1,000W to drive the associated full-range system. Its lightweight, switched-mode power supply auto-ranges to global mains voltages from 100 to 240V 50/60Hz, and Power Factor Correction smoothes out the mains current draw over the whole of the AC waveform. The operating range of the PSX is 48 to 150 Hz, with a stated peak SPL capability of 136 dB at one meter.

Onboard DSP performs delay, crossover and EQ functions, while the PSX plus full-range system can be controlled and monitored from a laptop or wireless tablet PC via VU-NET proprietary software. PC connection can be made directly via micro USB, or via Martin Audio’s proprietary U-NET network and Merlin loudspeaker and network management system.

The PSX internal memory allows factory plug-and-play or user-generated DSP preset "snapshots" of the PSX/full-range combination to be recalled by means of a preset selector button on the rear panel, instead of using computer control.

The PSX’s tour-grade plywood enclosure is coated in hard-wearing polyurethane and its Declon backed steel grille is pre-curved to resist deformation in the field. It includes a pole-mount fitting in the top surface, bar handles and protective skids. When stacked, the skids on the base of the upper PSX enclosure are said to align with recesses in the top of the enclosure below.
