B&C Speakers 18SW100

A B&C 18-Inch Designed for the Subwoofer Range: When the "SW" Series Targets Performance

The B&C 18SW100 embodies the spirit of the brand's professional subwoofer speakers: prioritizing power handling, mechanical robustness, and reliable performance in demanding bass enclosures. With its 18-inch (46 cm) format and neodymium motor, it meets the needs of both mobile systems and fixed installations where authoritative bass is required, capable of staying clean at high levels. Its positioning is clear: a low-frequency transducer designed to "drive" a bass enclosure, rather than a versatile speaker aimed at low-mid frequencies.

Intended Uses and Users

This 18-inch subwoofer speaker is aimed at integrators, enclosure manufacturers, sound technicians, and DIY audio enthusiasts who want to build or refurbish a high-efficiency bass enclosure. It is particularly relevant for live sound reinforcement (concerts, DJs, events), clubs, or performances where impact and bass extension must remain consistent over time. Its sensitivity of 97 dB (1 W/1 m) facilitates achieving high output levels, and its recommended tuning (200 liters at 33 Hz) provides a concrete basis for designing a bass-reflex enclosure oriented towards sub frequencies.

Design and Key Features: Efficiency, Excursion, and Durability

The 18SW100 combines an architecture designed for low frequencies with material choices suited to stage demands: heat buildup, large excursions, vibrations, and humidity. The goal is to maintain control and coherence when the enclosure is driven hard, while limiting component fatigue over time.

100 mm Voice Coil: Handling Power and Maintaining Control

The 4-inch (100 mm) copper wire voice coil is central to power handling. It contributes to the speaker's ability to accept sustained signals typical of continuously driven subs, while maintaining a stable response. Paired with the motor design, it aims for reliable operation at high levels with good control of the moving assembly.

Suspension and Centering: Mechanical Stability at High Excursion

With an Xmax of 12.5 mm, this model is designed for significant excursion. The triple-roll suspension and double siliconized spider contribute to stability and centering, two essential criteria to limit mechanical noise and preserve linearity when the sub delivers repeated impacts. This type of moving assembly is particularly appreciated in low-tuned enclosures where the cone can be heavily stressed depending on the program.

Treated Cone and Field Use: A Sound Reinforcement-Oriented Approach

The radial cone features waterproof treatment on both front and back, a tangible advantage for sound reinforcement applications where exposure to humidity, dust, or temperature variations can occur. The expected result: better consistency over time and a more reliable speaker for touring, rental, or installation in demanding environments.
