B&C Speakers - 14NDL88 4 Ohm Recone Kit

The 14NDL88 is often chosen for systems that require clean low-midrange articulation and good dynamic reserve, while maintaining a contained moving mass. When the diaphragm or suspension shows signs of wear, overall performance is affected long before the driver stops working altogether. The role of a dedicated diaphragm repair kit is to restore the mechanical integrity of the transducer and its original vibratory behaviour.

This 14NDL88 4 Ohm kit uses the same diaphragm profiles, suspension materials and voice coil geometry as the original model. The aim is not to improve or transform the loudspeaker, but to enable it to recover the mechanical and electro-acoustic parameters for which it was designed. The coherence of the low-midrange register, the rapidity of attacks and stability in sustained operation are thus recovered without altering the tonal balance.

Installation can be carried out as part of professional maintenance or in a specialist workshop, provided you have the appropriate centring equipment and an adhesive compatible with the materials in the kit. The procedure does not require any modification of the crossover or speaker settings, so there is no need to reconfigure the system or readjust the tuning of the load volume.

Choosing a re-bonding kit means that the life of the loudspeaker can be extended for a long time to come, while preserving the sound identity of the installation, which is particularly relevant in environments where the coherence of the broadcasting equipment is important.
