PMC has unveiled a new twotwo sub1 active subwoofer at the NAMM show.
The new unit is a low-distortion, active subwoofer featuring PMC's ATL bass-loading technology, Class D amplification, and DSP-based filtering and bass management, which according to PMC extends bass output significantly with negligible harmonic distortion.
The built-in amplifier delivers 400W of power to the sub, which has an active frequency response from 22Hz to 200Hz. The sub1 can be deployed in a 2.1 configuration with twotwo series monitors to gain extra bass extension and headroom, or reproduce the low frequency effects (LFE) channel in a surround monitoring system.
The two long-throw bass drivers employed in the twotwo sub1 are a bespoke PMC design using natural materials, with a low-mass, ultra-stiff doped-paper cone to deliver unparalleled transient response. The elegant cabinet dimensions makes the sub1 easier to place than typical cube-shaped subwoofer designs.
The sub1 features an AES3 XLR input with a built-in high-quality sample rate converter, and can thus accept digital signals at any sample rate up to 192kHz. A pair of balanced stereo analogue inputs on XLRs is also available, and both sets of inputs are always active regardless of which sources are connected; switching between the sources is carried out from the rear panel or the optional desktop twotwo remote. The digital input is also passed through to the sub's analogue and digital outputs for connection with other devices, allowing the twotwo sub1 to be used as a high-class D-A to drive other analogue monitors from a digital stream if required. A single parametric equaliser is provided to assist with in-room alignment, and the analogue and digital outputs can be high-pass filtered to feed satellite speakers in a 2.1 configuration.
