PMC Twenty5 Sub
Active PMC subwoofer with acoustic line loading, integrated class D amplification and DSP to precisely adjust bass for both music and home cinema.
Description
The Twenty5 Sub is an active subwoofer from PMC, designed to complement a hi-fi or home cinema installation by delivering precise, controlled bass at any listening level. It integrates equally well into a stereo system dedicated to music or a multichannel film-oriented setup.
Its design is based on a 3-metre quarter-wave acoustic line loading combined with two 17 cm G-Weave drivers, a combination that allows extension down to 22 Hz while maintaining a taut, controlled sound. Amplification is handled by a 400 W RMS class D module developed by PMC, known for its low distortion, and controlled by an integrated DSP offering low-pass filtering, variable phase adjustment and parametric equalisation with adjustable gain. These settings allow the subwoofer to be adapted to the acoustic characteristics of the listening room. Connectivity comprises two stereo XLR analogue inputs and one stereo XLR analogue output, allowing balanced connections with the rest of the system.
This subwoofer is aimed at demanding hi-fi or home cinema enthusiasts wishing to reinforce the bass register without sacrificing precision or coherence with quality main speakers. Its versatile settings make it a sound choice for rooms with varying acoustic characteristics.

What to check before buying used
On this subwoofer with quarter-wave acoustic line loading, listen carefully to the two 17 cm drivers at low frequencies: a rubbing noise or a loss of bass firmness may indicate worn suspensions. Check that the integrated DSP (low-pass filtering, variable phase, parametric equalisation) is working properly and that there is no crackling from the class D amplification module. Finally, check the condition of the XLR connectors and the cabinet, particularly the corners of this bulky 25 kg unit, which are often marked during handling.
