B&C 12SW115 – 12″ High-Output Subwoofer Driver
The B&C 12SW115 is a high-energy 12-inch subwoofer driver built for pro audio systems that require serious bass impact, robust power handling, and efficient performance. With its large voice coil, advanced motor design, and vented cooling features, it delivers powerful, low-distortion sound ideal for subwoofer cabinets in touring setups, clubs, installations, or any system where bass presence matters.
Solid build quality combined with modern thermal and mechanical engineering make the 12SW115 capable of performing under the harsh demands of live sound, long hours, and high SPLs, while retaining control and clarity in its low-end output.
Deep, Clean Bass & Wide Usable Bandwidth
With a nominal diameter of 320 mm (12 inches), the 12SW115 moves enough air to generate deep, punchy bass. Its frequency range of 40 Hz to 1500 Hz gives it a broad, usable bandwidth—covering deep bass fundamentals and extending well into low-mid frequencies without losing definition.
Whether being used in a vented subwoofer cabinet or as part of a bass driver module in full-range systems, the 12SW115 offers authoritative output and maintains tone integrity under load, avoiding muddy or sluggish performance.
Exceptional Power Handling & Thermal Stability
The 12SW115 boasts nominal power handling of 1700 W and continuous program power of 3400 W, granting substantial headroom for dynamic peaks and demanding audio content. Its 115 mm (4.5-inch) copper voice coil, along with a ventilated magnetic gap and advanced motor geometry, helps dissipate heat effectively.
These features ensure that the 12SW115 maintains consistent output, with minimal compression, even during prolonged sessions at high volume, making it reliable for professional use.
Strong Efficiency for Output
With a sensitivity of 92.5 dB (1W/1m), the 12SW115 converts amplifier power into acoustic pressure efficiently—especially for a subwoofer with this level of power capability. This sensitivity aids in achieving loud, impactful bass without needing an excessive amplifier, helping retain better system headroom and reducing noise or distortion from the amplification chain.
Stable Impedance & System Integration
The driver operates at a nominal impedance of 8 Ω, with a minimum impedance around 6.5 Ω, providing stable and predictable electrical behavior when paired with amplifiers or crossover networks.
This stability makes it easier for system designers to integrate the 12SW115 into both passive and active subwoofer architectures, ensuring fewer surprises and more consistent performance across installations.
Built for Durability and Real-World Use
Constructed with reinforced components like a double silicone spider, optimized excursion-lead wires, and an aluminium demodulating ring to reduce distortion, the 12SW115 is designed for heavy use. The vented gap, premium cone materials, and robust mechanics support high excursion and high power without mechanical fatigue or thermal failure.
These build traits help maintain long-term reliability, especially in conditions of heavy use or challenging acoustic environments.
Ideal Applications
The 12SW115 is especially useful in:
- Compact subwoofer cabinets for club or studio applications
- Touring subs or front bass modules needing both punch and finesse
- Full-range top boxes with bass module requirements
- Fixed installations in venues where space is limited but bass should still be powerful
- OEM builds requiring dependable performance and high output
Its power, sensitivity, and mechanical strength make it flexible for many design needs where bass impact, clarity, and durability are non-negotiable.
