B&C Speakers - 18PS76 4 Ohm

Designing a good subwoofer often involves juggling impact, precision, and endurance. The 18PS76 from B&C Speakers fits this bill with a well-balanced design.

We're looking at an 18-inch speaker that doesn't try to impress with unnecessary technical gimmicks, but rather with its ability to deliver dense, well-controlled bass, which, above all, is usable in a wide range of configurations.

It easily reaches up to 2 kHz, which opens the door to generous two-way systems or versatile subwoofers that need to maintain definition even in the upper bass range.

Inside, a 3-inch copper voice coil is wrapped around a fiberglass support, all driven by a reliable and robust ferrite driver, typical of B&C. Nothing flashy here, but a proven design that withstands long sessions at high volume without flinching.

The 4-ohm impedance allows for efficient use of the amp's power, and with a sensitivity measured at 99 dB, you don't have to force yourself to get the right level.

Mechanically, the numbers speak for themselves: a resonant frequency of 49 Hz, a balanced Qts of 0.31, and a linear excursion of ±7 mm, extendable to ±9.42 mm depending on the configuration.

In short, it pushes hard, stays clean, and breathes. The aluminum mount ensures the overall rigidity, the cone of over 1200 cm² draws air without unnecessary vibration, and the whole unit is well ventilated to prevent overheating, even when the pace intensifies.

Whether you're working on a responsive bass reflex subwoofer, a full-range speaker with plenty of punch, or a more ambitious custom project, the 18PS76 has everything you need to become a reliable, solid, and effective foundation.
