Speaker life expectancy


I have a couple pair of old Vandersteens. 2c model which I bought new almost 18 years ago and a pair of 2c(e or i) which are about 8 years old bought used. Both sets still sound fine to me, and mine have always been given TLC. There must come a point when speakers go bad. Will this be readily noticable, or have they been gradually detiorating and my listening has adjusted accordingly. Vandersteen has a set up where I can send the speakers back for a refurb (not sure of the cost though). These are used in my HT and I have an audio set up which sounds much better using NHT 2.9s. I always thought the sound difference was due to the different speakers. Now, I'm not so sure. Thanks.

My guess is that while there may be some degradation of the cone materials and surrounds over time, there is no life time limit on the functionality of speakers, especially Vandersteens. They've always been built on the premise that a good design can and should last a long time, as opposed the trying to be the flavor of the month. My recommendation would be to check out the refurb program, because this company is known for supporting their lines and customers. In fact, many of their speakers are sold based on the fact that they can be easily upgraded, which leverages your original investment. In closing, I'm willing to bet that of all the components in an older system, the speakers are often the least likely to get 'left behind' with changing technology. If you're itching to spend $$, you might find better ROI on your sources, especially if they are older digital pieces. Hope this helps.
At that age, the speaker surrounds could well have deteriorated to the extent that refurbishment will add tightness and definition - this is particularly noticeable with bass units. But there is no guarantee that I can give you that a refurbishment is required. Any other problems of drive unit, cross-over or cabinet aging should be quite noticeable.

I've seen many cones deteriorate significantly over time. Have you checked them (just remove the grilles) ?
