B&C Speakers - 21DS115 4 Ohm Recone Kit

The Recone Kit B&C Speakers 21DS115 4 Ohm is the ideal solution for restoring the performance of a loudspeaker designed for the most powerful cabinets. With this kit, you get all the original components: TWP-treated radial cone sealed on both sides, triple-roller suspension, double silicone spider and 116 mm aluminium voice coil mounted on a fibreglass support. This pack provides a faithful refurbishment, guaranteeing the same robustness and reliability as the new model.

Bass reproduction remains impressively deep, thanks to a resonant frequency of 30 Hz and an extended bandwidth from 30 to 1000 Hz. The loudspeaker is once again capable of handling 1700 W AES continuously (3400 W peak) with a sensitivity of 99 dB, making it a formidable choice for sound reinforcement in very large spaces while maintaining a powerful, defined bass.

Its Xmax of 15 mm and permissible excursion of ±17 mm provide outstanding mechanical strength, making it ideal for cabinets tuned for modern music and applications requiring a high SPL reserve. Combined with a neodymium motor with internal slug and a flux density of 0.8 T, this kit delivers the dynamics and precision expected by touring and fixed installation professionals.

Beyond the technical aspects, this Recone Kit offers a cost-effective alternative to the complete replacement of the 21DS115. It extends the life of the loudspeaker while retaining the same sound colour and mechanical characteristics, essential for systems where every detail counts.
