B&C 15SW100 – 15″ High-Output Subwoofer Driver
The 15SW100 is a professional 15-inch subwoofer driver from B&C, engineered for demanding sound reinforcement where power, clarity, and reliability are essential. Built with touring and installation use in mind, it delivers consistent low-frequency performance with excellent efficiency. The driver is designed to handle sustained high power while maintaining tight, defined bass output, making it a strong choice for subwoofer enclosures that need to perform under pressure.
Low-Frequency Depth and Range
With a nominal diameter of 380 mm (15 inches), the 15SW100 offers the diaphragm surface and excursion needed for impactful low-frequency reproduction. Covering a frequency range from 40 Hz to 1500 Hz, it extends deep enough to produce weighty bass fundamentals, while also retaining flexibility into the upper bass and low midrange. This wide working range makes it versatile across applications—whether used strictly for subbass reproduction or as a bass section in multi-way systems.
In smaller enclosures, the driver focuses on punchy, controlled bass, while in larger vented cabinets it is capable of reaching down into the sub-40 Hz region with authority. This adaptability makes the 15SW100 a strong fit for both compact sound systems and large-scale PA rigs.
Serious Power Handling
At its core, the 15SW100 is built for high power. With a nominal power handling of 1500 W and a continuous program rating of 3000 W, it offers substantial headroom for modern amplifier power. Its 100 mm (4-inch) copper voice coil is wound to withstand thermal stress, allowing the driver to sustain high SPL output without thermal compression compromising the sound.
This durability is particularly important in live sound environments, where subwoofers are driven hard for extended periods. The 15SW100 is engineered to maintain output consistency even when pushed to its limits, ensuring audiences experience clean, impactful bass throughout the performance.
Efficiency and Sensitivity
With a sensitivity rating of 95 dB (1W/1m), the 15SW100 is efficient for a subwoofer of its size and output class. This means it is capable of delivering strong output levels with relatively modest amplifier power, although it is equally at home paired with large, high-wattage amplifiers for maximum system headroom.
For system designers and sound engineers, this efficiency translates to greater flexibility—whether the goal is maximum SPL, clean headroom, or energy-conscious system design.
Stable Electrical Performance
The driver is rated at a nominal impedance of 8 ohms, with a minimum impedance around 6.5 ohms, ensuring stable amplifier loading and predictable performance across a wide range of system configurations. This allows the 15SW100 to be easily integrated into standard professional setups, whether used singly, in multiples, or as part of a larger subwoofer array.
Its stable impedance curve helps avoid unexpected amplifier stress, making it a safe and reliable choice when system reliability is non-negotiable.
Mechanical Reliability
Beyond its power handling, the 15SW100 is built to handle the mechanical demands of heavy bass reproduction. Its suspension system balances linear movement with control, preventing distortion while allowing for the excursion required to generate deep bass. The cone, surround, and spider are constructed to resist fatigue under continuous operation, ensuring long-term reliability.
This durability makes the 15SW100 especially well-suited for touring systems and permanent installations where downtime is not an option.
Application Versatility
The 15SW100 is designed for a broad range of applications:
-
Touring sound systems requiring robust subwoofer sections with high SPL capability.
-
Installed systems in venues such as clubs, theaters, and houses of worship, where reliable bass is essential.
-
Custom cabinet designs for OEM or independent builders looking for a driver that balances power, sensitivity, and durability.
-
Hybrid bass solutions, where the driver needs to handle both subbass and upper bass content without loss of clarity.
Its combination of low-frequency extension, output, and efficiency makes it one of the most dependable choices in the 15-inch category.
