In general, most woofers (low frequency drivers) are pretty straightforward, they should be reconed to duplicate the original sound and eliminate worn, tired, and deformed parts. Some use such oddly dimensioned parts that it is better to just replace the foam and keep the original internal parts intact, but in general reconing is better. I can rebuild or replace some tweeters and horn drivers but usually I need to see the original unit to determine this. This is a non-destructive process and if you have something you want me to look at you should send it in with your address, email, and telephone number for me to contact you with the options.
This entails stripping the driver down to the original metal chassis (magnet, basket, etc.) and building it as if it was a new part. This is the most common repair required by damaged PA or musical instrument speakers. Duplication of the original performance is the goal. I can also usually repair damaged magnet structures as well. My assembly materials and workmanship show the result of years of manufacturing experience. You can expect a reconed driver to sound like new and give many years of satisfaction.
This process consists of accurately replacing the aged annular foam surrounds.
This process also involves removing and replacing or re-attaching the dust cap in order to perform the essential task of accurately centering the voice coil during the process. Lead wires will also be replaced if necessary. I always test and examine the drivers first, and will inform you of the need for a complete reconing if the original parts are too worn or damaged to be returned to service by this method.
This service is often incorrectly referred to as "reforming".
Something that can be very worthwhile doing is rejuvenating speakers that have "good" cabinets but lack the quality of sound that we would demand from a good speaker. By "good" cabinets, I mean ones that are solidly built, and usually very attractive. Often older speakers (say, pre-1968) just weren't capable of the great sound my drivers provide, but they were still manufactured very well, with wood veneered cabinets and very solid jointwork. These speaker cabinets will sometimes still have great nostalgic value to their owners.
What I do is remove all the old speaker parts, wiring, etc., then I rebuild the speakers with my high quality parts, crossovers and terminal connections, test them thoroughly, and you can enjoy music like never before! Even if the holes cut in the front of the box are not convenient, this can still be remedied by attaching an extra layer of MDF to the front with the appropriate holes cut into it. A typical project would be to use my PRO 005 woofer and PRO 002 M2 tweeter in a 1.5-2 cubic foot cabinet. In this case I would be installing a "kit" of parts that costs $363.00 / pair. If not too much cabinet modification is required, labor costs would be in the / to / range. If you think your speakers would benefit by this process, please contact me and we can discuss it.
The result when I am finished is essentially a current HUMAN Speakers product.
Magnet Structure Service
This is a relative latecomer to my offerings. Sometimes we encounter old speakers with magnet structure parts which have come loose and shifted, jamming the voice coil. This is generally unrepairable, and the part must be replaced. Sometimes replacements are very hard, or impossible, to come by.
What I do is strip the "soft" parts from the chassis, demagnetize the structure, take it apart, clean the offending surfaces, make a custom fixture to reassemble them on the lathe, reassemble the magnet structure, remagnetize the assembly, and recone the driver on the resulting clean, functional chassis.
This is limited to ceramic magnet drivers. The magnet must not be cracked or broken, although we all like a challenge. The cone, coil, etc. must not be removed, as I will need them to make sure that the reconing parts are correct and bring the driver back to originality.
