The hd PLB is an extremely compact, array-capable subwoofer in the elegant hd PL-series column loudspeaker design with astonishing bass reproduction for combination with any mid-high loudspeaker for full-range applications. The inconspicuous hd PLB subwoofer element consists of ten powerful 3.5“ high-excursion chassis with a continuous power of 150W RMS. Thanks to the proven single-roll surround technology for a large linear excursion and the best possible impulse fidelity, the 104 x 108 mm slim subwoofer has a frequency range of 40 – 160 Hz (-6 dB) and is therefore ideally suited for invisible applications in restaurants, conference rooms, museums, theaters and churches . The nominal impedance is  6 Ω, so that different sound reinforcement scenarios can be efficiently implemented with the installation amplifiers of the hd Qi-series.

The hd PLB subwoofer module has the same housing dimensions as the hd CCX- and PL-series and, thanks to MIX & MATCH, e.g. can be combined with an hd C5CX or hd PL16 to form an inconspicuous but dynamic full-range column loudspeaker with a transmission range of 40 – 22,000 Hz. On request, this combination can also be manufactured in a continuous housing.
