Driver refoaming

Refoaming is the exchange of the beading that connects the membrane and the basket with one another. Here, the driver is dismantled, cleaned and examined for any errors. After installing the new beading, the speaker undergoes a final test. The beading is made of special foam that remains stable for 20-years. Nevertheless, it is subject, like all foams to an unstoppable chemical decomposition, which may be accelerated by environmental influences. You should replace any partial hardening of the beading, cracks or holes.

Reconing is the replacement of not only the membrane, but also the complete driver. This means that the driver is completely dismantled, magnet and cast basket are cleaned, and all parts such as membrane, voice coil carrier, the coil and beading are replaced by new ones. In this version, the old driver is replaced with the latest most modern driver. It is thus restored to a new-like condition. Again, at the end the devise undergoes a series of detailed tests.
