B&C Speakers 15PL100

A performance-oriented 15" B&C for the low/bass-midrange area

The B&C 15PL100 is a 15" (38 cm) loudspeaker designed to efficiently cover the low and bass-midrange region, where impact, dynamics, and stability make the difference. Its architecture is based on a ferrite magnet and a moving assembly sized to handle significant demands while maintaining a controlled and usable response in sound reinforcement.

For which speakers and users?

This model is aimed at integrators, speaker manufacturers, contractors, and DIY enthusiasts looking for a transducer capable of handling the low end on a front speaker, a powerful monitor, or a subwoofer focused on punch (depending on filtering and design). With an 8 Ohms impedance, it easily integrates into classic configurations (single unit or multi-way systems) and is particularly suited for setups targeting tight, fast, and present bass.

Design and key points: power handling, control, and consistency

4.0" (100 mm) voice coil: thermal stability and endurance

The 4.0" (100 mm) copper wire voice coil contributes to the 15PL100's ability to handle high levels over time. This sizing is an asset for maintaining durability when the system is driven hard, especially in frequency ranges where the loudspeaker is most stressed.

Triple roll suspension and double siliconed spider: mechanical control

The triple roll suspension and double siliconed spider ensure stable cone guidance with consistent behavior even at high excursion. The Xmax of 7.0 mm highlights the "performance" orientation: the loudspeaker is designed to remain controlled when displacement is demanded, essential for cleaner and less "muddy" bass reproduction.

Recommended enclosure tuning: a reliable design basis

To optimize performance, the recommended enclosure is 80 liters with a tuning at 50 Hz. This guideline provides a concrete starting point for designing a tuned enclosure, aiming for a balance between extension, power handling, and efficiency. With an Fs of 37 Hz and a Qts of 0.2, the 15PL100 fits into a logic of clean and controlled bass, particularly interesting when the cabinet design and filtering are executed precisely.

Cone geometry: exponential cone

The exponential cone promotes efficient projection and good clarity in the bass-midrange area. It is a relevant choice for systems where attack and definition are desired, while maintaining the necessary foundation in the low end.
