B&C Speakers 15 PS 100

A 15-inch Driver Designed for Sound Reinforcement, Bridging Bass and Low-Midrange

The B&C 15PS100 is a 15-inch (38 cm) speaker intended for sound reinforcement cabinets where power handling, solid low-frequency response, and good articulation in the low-midrange are sought. Its "bass / low-mid" positioning makes it a relevant choice for setups that need to remain effective in the impact zone (kick drum, low snare, low vocals) while maintaining a usable bass foundation, depending on the enclosure volume and tuning.

Intended Uses and Speaker Projects

This model is aimed at integrators, rental companies, speaker builders, and audio DIY enthusiasts who want to build a reliable speaker for demanding performances. It is particularly suitable for punch-oriented bass-reflex subwoofers, full-range heads with appropriate crossover, or 2-way systems where the 15-inch covers bass and low-midrange before handing off to a compression driver and horn. With a rated sensitivity of 95 dB (1 W / 1 m), it is also well-suited to amplifications that prioritize efficiency and dynamics.

Key Features and Design Choices

4-inch Voice Coil: Thermal Endurance and Stability Under Heavy Use

The 4-inch (100 mm) copper wire voice coil helps handle the rated 1400 W AES power while promoting consistent performance when the speaker operates at high levels for extended periods. This architecture is typically sought in sound reinforcement to limit level loss due to heating and maintain controlled response during the most demanding passages.

Triple Roll Suspension and Xmax: Excursion Control

The triple roll suspension, combined with a rated Xmax of 8.0 mm, aims to maintain clean behavior when the speaker is driven in the bass range. The expected result is better control of cone displacement, clearer bass, and a sense of firmness, especially on fast transients.

Treated Radial Cone: Moisture Resistance and Durability

The radial cone features waterproof treatment on both front and back. This is particularly useful in stage environments or mobile use, where the speaker may be exposed to humidity, temperature variations, or repeated transport conditions. The goal is to preserve the mechanical stability of the cone and consistent response over time.

Double Silicone Spider: Centering and Reliability

The double silicone spider reinforces the centering of the moving assembly and contributes to the overall robustness of the transducer. In a sound reinforcement system, this mechanical safeguard is important to limit drift during large excursions and maintain steady operation throughout performances.
