B&C 12PS100 High-Power 12-Inch Subwoofer Driver for Professional Sound Reinforcement Systems
The B&C 12PS100 is a high-performance 12-inch low frequency driver engineered for professional subwoofer and midbass applications where high output, controlled low-frequency extension, and long-term reliability are essential. Designed as part of B&C’s PS series, this model is optimised for vented enclosure systems used in portable PA, installed sound reinforcement, and compact subwoofer designs that require strong output from a relatively small cabinet volume.
With a large 100 mm voice coil, high power handling, and a carefully engineered motor structure, the B&C 12PS100 delivers the kind of low-frequency authority and thermal stability expected in modern professional loudspeaker systems. It is particularly well suited to applications where impact and efficiency are more important than ultra-deep sub-bass extension.
High-Power Motor System with Strong Thermal Control
At the core of the B&C 12PS100 is a robust ferrite motor assembly combined with a 100 mm (4-inch) copper voice coil. This large-diameter coil is designed to handle significant thermal load while maintaining mechanical stability during extended high-power operation.
The copper winding ensures excellent heat dissipation, reducing the risk of power compression under sustained load. Combined with a glass fibre former, the voice coil structure maintains rigidity and dimensional stability even at elevated temperatures.
The motor system produces a flux density of approximately 1.05 T and a BL factor of 22.5 Tm, giving the driver strong electromagnetic control over cone movement. This results in tight, controlled bass response with reduced distortion at higher excursion levels.
A double silicone spider system is used to stabilise cone travel and improve linearity, ensuring predictable behaviour under dynamic programme material.
Subwoofer-Focused Performance with Controlled Bandwidth
The B&C 12PS100 is designed to operate effectively in the 45 Hz to 1000 Hz range, making it suitable for subwoofer and low-mid reinforcement duties in professional systems. The driver delivers a sensitivity of approximately 93 dB, allowing strong acoustic output without excessive amplifier power requirements.
With a resonance frequency (Fs) of 44 Hz, the driver is capable of reaching into the low bass region while maintaining control and efficiency. However, its primary strength lies in punchy, high-impact low frequencies rather than extreme sub-bass extension.
The relatively low Qts of 0.27 and EBP of approximately 152 indicate a design strongly suited to vented enclosure applications. This makes the B&C 12PS100 ideal for bass-reflex subwoofer systems where output and efficiency are prioritised.
The moving mass of 106 g contributes to controlled low-frequency response, while maintaining enough inertia to deliver impactful bass reproduction suitable for live sound environments.
Enclosure Design and System Integration
In practical system design, the B&C 12PS100 performs optimally in compact vented enclosures around 40 litres, tuned to approximately 48 Hz. This alignment provides a balance between low-frequency extension and punch, making it suitable for portable PA subwoofers and installation systems where cabinet size is limited.
The cone assembly features waterproof treatment on both sides, improving durability in environments where humidity or exposure may be a concern. The radial cone geometry and triple-roll surround design help maintain stable excursion behaviour, reducing distortion during high-output operation.
With an Xmax of 8 mm, the driver provides sufficient linear excursion for professional subwoofer applications without compromising efficiency. This makes it a practical choice for systems requiring consistent performance under demanding operating conditions.
Reliable Power Handling for Professional Applications
The B&C 12PS100 is rated at 700 W AES power handling and 1400 W program power handling, giving it the capacity to operate in high-demand environments such as live sound reinforcement and installed PA systems.
The combination of a large copper voice coil and efficient motor cooling design ensures stable thermal behaviour under continuous use. This allows the driver to maintain consistent performance over long operating periods, even in high SPL applications.
Its balance of efficiency, power handling, and controlled low-frequency behaviour makes it a reliable solution for system designers building compact subwoofer systems or midbass reinforcement cabinets.
