British loudspeaker manufacturer PMC (Professional Monitor Company) is delighted to announce that it is launching the latest addition to its global award winning twenty series range of domestic loudspeakers – the twenty Sub. This new subwoofer, which has been designed for use with both music and movies alike, builds upon PMC’s world-class design pedigree, combining the finest drivers available with the unique ATL™ (Advanced Transmission Line) bass loading principle, sophisticated Class-D amplification, and ultra-precise DSP control.
The twenty Sub’s design DNA is deeply rooted in the world of professional audio, using tried and tested technology that has continuously proven itself by producing music hits as well as Hollywood blockbusters. Thanks to PMC’s expansive research into room acoustics and ergonomics, the twenty Sub is a truly adaptive design and offers a wide-range of placement and connectivity options, depending on room size and applications. Equally at home in large or small rooms, the twenty Sub will deliver precise, dynamic results, regardless of the volume level.
Consisting of a tall slender form that is compact enough to hide away, the twenty Sub delivers an enthralling true performance that can both shake the rafters for movie fans or add the bass subtleties required by music lovers. The elegant cabinet, which is braced throughout by multiple internal baffles offering superior rigidity and ultra-low cabinet talk, provides the perfect housing for PMC’s designed and built drive units and cutting edge electronics. Further reducing colouration and adding extra substance to the cabinets footprint, an integral high mass, resonance absorbing plinth forms the base. Featuring a convenient aperture for cable management, the plinth also houses the threads for M8 reversible stainless steel spikes.
As with all PMC speaker designs, the twenty Sub utilises ATL™ (Advanced Transmission Line) technology. With an effective length of 3m / 9 ½ feet, the transmission line delivers a smooth, flat response down to 22Hz, enabling the twenty Sub to perfectly integrate into a wide range of applications. The two long-throw 7”/170mm custom-designed PMC bass drivers feature ultra-light and ultra-stiff doped-paper cones mounted in a cast magnesium chassis, which deliver unparalleled transient response.
At the heart of the twenty Sub is an electronics package that is professionally proven and developed from PMC’s extensive heritage in the professional audio industry. Consisting of PMC’s 400w ultra low distortion Class D audiophile amplification, which features powerful DSP circuits, filtering and bass management functions, connectivity is in the form of balanced stereo analogue (RCA unbalanced convertors are included) and AES/EBU digital inputs. All outputs are configured to be unprocessed or high-pass filtered, with fixed or variable gain. The input source, analogue input sensitivity, gain trim and overall volume are all adjustable, as are the twenty Sub’s low-pass filter slope and frequency, which allows tuning across five pre-determined steps. Additionally, the phase can be adjusted and a single parametric equaliser is provided that is ideal for in-room tuning. The analogue and digital outputs can be high-pass filtered, if required, to feed either active satellite speakers or back to a power amplifier to drive the main pair in a passive 2.1 configuration.
