30 yr old speakers- time to replace drivers?


I have a pair of NHT VT1 speakers. The drivers seem to be in good shape. They have paper cones and rubber surrounds. After 30 yrs, should I upgrade crossovers and replace drivers?

The NHT VT is a good loudspeaker, but it's not a special loudspeaker.  I have a pair (VT-2, I think) in a bedroom mainly used for watching video and they work well.  I would advise not putting much, if any money into them.    NHT won't help you with any info on the crossovers or drivers.  So unless you're a real DIY kinda' fella it's not worth the money to even figure out what you would need to change. As long as the drivers are in good shape you're pretty much there.  The loudspeaker are what they are.

A true low cost change would be to replace the internal wiring.

@pureclarity sorry, I missed the problem statement in your OP! do you hear distortions, or any kind of sound problems' to fix? If not, why to “fix” anything?

Speaker design (fix) can be very challenging, and needed some assessment, x-over sims, measurements etc, not available to everyone.

The Xovers are totally worn out ,having upgraded Xovers a long time the capacitors dry out for sure after 15 years or less , you loose detail and then uneven output per speakers ,then just stop working.

I agree, I would not put money into a thirty year old speaker. There have been huge improvements in every aspect of design.

Crossovers can last waaayyy more than 15 years. Hell I just sold a 50 year old sansui 9500 that would put the majority of integrated amps under 5k to shame. I know it’s not a speaker. Original caps other than a few small input caps replaced. If there’s nothing that sounds “off” I wouldn’t mess with it. 
 

upstairs system has original Paradigm Studio Monitors. Same thing 30 years old sound awesome, lacking no where compared to my main system downstairs.
