PMC TwoTwo Sub 1 - Active Subwoofer Monitor Speaker (Single)

PMC TwoTwo Sub 1 - Active Subwoofer Monitor Speaker (Single)

The PMC TwoTwo Sub1 is an ultra-low distortion, active subwoofer which can be used in a 2.1 configuration with twotwo series monitors to gain extra bass extension and headroom, or it can be used to reproduce a low frequency effects (LFE) channel in a surround monitoring system.

The electronics built into the cabinet include an ultra-low distortion Class-D power amplifier, with DSP-based filtering and bass management functions. Balanced stereo analogue and AES3 digital inputs are accepted, and are combined to feed the subwoofer system, as well as being passed through to the analogue and digital outputs for connection with other devices.

The input source, analogue input sensitivity, gain trim, and overall volume are all adjustable, as are the subwoofer´s lowpass filter slope and frequency. Additionally, the phase can be adjusted and a single parametric equaliser is provided to assist with in-room alignment. The analogue and digital outputs can be high-pass filtered, if required, to feed satellite speakers in a 2.1 configuration.

This subwoofer builds upon PMC´s world-class design pedigree, combining the finest drivers available with the unique (Advanced Transmission Line) bass loading principle, sophisticated Class-D amplification, and ultra-precise DSP control. PMC´s unique technology uses contemporary materials to provide optimised absorption of unwanted low-midrange energy within the cabinet, while extending bass output significantly with negligible harmonic distortion.

The two long-throw bass drivers employed in the twotwo sub1 subwoofer are a bespoke PMC design using natural materials, with an ultra-light and ultra-stiff doped-paper cone to deliver unparalleled transient response. The elegant cabinet dimensions makes the twotwo sub1 easier to place than typical cube-shaped designs.
