B&C Speakers 15 TBX 100

A B&C 15-inch Subwoofer: A "Performance & Reliability" Approach

The B&C 15 TBX 100 SUB fits the spirit of dedicated bass drivers for bass cabinet applications: consistent efficiency, parameters suited to a tuned enclosure, and mechanical architecture designed to handle excursion. With a resonance frequency at 35 Hz and a recommended tuning at 35 Hz, it clearly targets solid reproduction of the lower spectrum in a bass-reflex configuration, for powerful and durable sound reinforcement systems.

Who Is This 15 TBX 100 SUB For?

This transducer is aimed at integrators, speaker manufacturers, sound technicians, and DIY enthusiasts who want to build or recone a 15-inch bass cabinet focused on impact and depth. It is particularly suitable for sound reinforcement systems (mobile or installed) where consistency and high-level power handling are priorities, while maintaining a usable bandwidth up to 1.5 kHz to facilitate integration with various types of tops depending on filtering.

Design & Key Elements for Clean and Powerful Bass

Excursion, Control, and Mechanical Endurance

With an Xmax of 9.0 mm, the 15 TBX 100 SUB is designed to move air without collapsing as levels rise. The triple roll suspension and double siliconed spider contribute to stable cone movement, helping to maintain clearer bass, especially on modern energy-rich signals (kick, sub, synthetic bass).

Motor and Voice Coil: Consistency at High Power

The 100 mm copper wire voice coil is a central element to withstand the thermal and mechanical stresses of subwoofer use. Combined with a ferrite magnet, it aims for a solid motor structure and controlled response, ensuring reliable behavior in a properly sized and tuned enclosure.

Protected Diaphragm for Field Use

The radial cone receives a waterproof treatment front and back. This is a tangible advantage for sound reinforcement setups where the speaker may be exposed to ambient humidity, temperature variations, or intensive use, while retaining the expected mechanical qualities of a subwoofer driver.

Load Optimization: Recommended Tuning and Volume

To best utilize this model, the recommended enclosure volume is 114 liters with a tuning at 35 Hz. This guideline is valuable: it serves as a reliable basis for designing a coherent bass-reflex cabinet, aiming for deep bass and a response suited to sound reinforcement. Naturally, the port, internal damping, and filtering will influence the final result, but this starting point helps avoid risky compromises.
