PMC twotwo sub1 Brochure & Specs

The twotwo sub1 is an ultra-low distortion, active subwoofer

which can be used in a 2.1 conguration 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 amplier, with DSP-based ltering

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 low-

pass lter 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 ltered, if required, to feed satellite speakers in a

2.1 conguration.

This subwoofer builds upon PMC´s world-class design

pedigree, combining the nest drivers available with the

unique (Advanced Transmission Line) bass loading principle,

sophisticated Class-D amplication, 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

signicantly 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.

The optional RJ45 wired remote features all the

functions of the rear panel with an easy to use jog
wheel, making remote set up, input switching &

EQ of stereo or surround systems quick and easy.
