Frequently Asked Questions

At DSR, we've done our best to create a Web site that anticipates and satisfies our customers' needs. With that goal in mind, we've compiled a list of frequently asked questions. If you do not find an answer to your question here, contact us at info@dsraudio.com.

Q: What is the difference between “re-coning” and “re-building” a speaker?
A: There are several critical components in the construction of a speaker in addition to the cone.  Some of these other components can also degrade over time, much like the cone material can lose its strength or material integrity.  The passage of time can also cause the original alignment and spatial tolerances to shift over time.  And dirt, grime, humidity and other “gunk” can find their way into the many tiny areas within the speaker.  When we rebuild a speaker, we address all of the qualities of your speaker which will prevent it from operating at its peak performance and sonic capability.

Q: Can you make my vintage JBL’s sound more like Altec’s (Jensen’s, EV’s, etc)?
A: The tonal qualities of a speaker are the result of many design parameters, some of which can be changed - like cone materials and magnet materials - but the characteristic “voice” of speaker are primarily the result of the design itself.  For the most part, an Altec can be a “good Altec” or a “bad Altec”, a Jensen can be a “good Jensen” or a “bad Jensen”, where “good” means functioning properly and sounding beautifully and “bad” means functioning poorly and sounding less than beautifully.  But if you really want the characteristic voice of a JBL, Jensen, Gauss or other premium speaker, it is best to install that speaker.

Q: How long can I expect a speaker rebuild to take?
A: Occasionally, circumstances may cause a longer than usual delay in the rebuilding process, but typically we can get a speaker rebuilt and shipped out in 7 business days from the time it arrives in our shop.

Q: How bad can a speaker be and still be rebuilt?
A: We have actually successfully rebuilt speakers that have been dug up by a bulldozer in a landfill.  As you may guess, that level of degradation requires a higher than normal level of work and time.  A better question would be “Who would do such a heinous thing as to throw a vintage speaker in the town dump?”
