Older (vintage) discontinued speaker units:
In most cases, speaker units for speaker models manufactured in the 1970’s, 1980’s and even in the 1990’s, are no longer in production.
We cannot order discontinued drivers from the manufacturers, as it would take an order of hundreds of units (if they can still manufacturer the unit in question).
It will often than not be the case that speaker unit manufacturers do not have access to certain parts needed to produce older (discontinued) models.
For some of the more popular vintage speakers, like for example the JBL L100 Century, there are now companies offering copies / clones of the tweeters or other speaker units, which can be bought on e.g., eBay.
However, in most cases the only option for replacing the speaker units will be to either buy second hand original units on e.g., eBay or to find a company that specializes in restoring and repairing speaker units, hereunder discontinued vintage speaker units.
It is also important to note that it is not possible to swap a speaker unit with a different one, unless the two units have identical parameters.
This almost never happens, so do not spent too much time reading through manufacturer datasheets, your time is better spend hunting for second hand original units.
If a speaker unit model is swapped with a different one, a new crossover is needed and the sound would likely change, which is rarely wanted, especially for vintage speakers.
Current speaker units (still in production):
Some manufacturers offer a “voice coil repair kit” for certain tweeter models, but it is rare that replacement cones or other spare parts are available for mid-range units and woofers.
Repair kits when available must be ordered via our resellers.
When it comes to sending in a unit for repair it is in many cases more expensive than replacing it, when factoring in shipping costs, cost of parts and the work time of the person repairing the unit.
At Jantzen Audio, we do not offer speaker repair or restoration, so please contact either the speaker manufacturer directly or a company that specializes in speaker unit repair and refurbishing.
