B&C Speakers - 15PS100 4 Ohm Push Buttons

The 15PS100 4 Ohm Push Buttons is a 15-inch loudspeaker designed to meet the needs of modern PA systems. With a 100 mm copper voice coil on fibreglass backing, it supports 700 W AES and up to 1400 W peak. This robust design ensures uncompromising reliability, even in configurations where the acoustic load and sound intensity reach demanding levels.

Its bandwidth covers 35 Hz to 1500 Hz, so it can be used both as a compact subwoofer and as the low midrange in a larger system. Its sensitivity of 95 dB guarantees efficient reproduction, capable of producing powerful bass while preserving good definition. It is perfectly suited to tuned subwoofers for live performances and fixed installations.

The ferrite motor provides a stable magnetic flux, coupled with a BL factor of 19 Tm, which translates into excellent control of diaphragm movement. The result is a firm, controlled bass with no drag, capable of supporting a sustained rhythm in any musical context. With a Vas of 172 litres and an Fs of 31 Hz, this loudspeaker is cut out to go low in the sound spectrum.

Its ±8 mm Xmax and fabric suspension guarantee smooth, controlled excursion, even at high volumes. The 855 cm² diaphragm has a large displacement surface, ensuring that low frequencies are diffused widely and evenly. The overall design strikes a balance between raw power and musicality, avoiding saturation even under heavy use.

This model is particularly popular with loudspeaker contractors and designers looking for a high-performance, reliable and versatile 15". Its mechanical design and choice of materials make it a durable investment, suitable for both touring and long-term fixed installations.
