Replace Dynaudio woofers?

That being said the Xover is old and capacitors drying out for sure .

I just rebuilt a nice pair of contour 3.4  they sound much better then even their new30 model .

If only worth $500-$900 used, I would make it easy without spending too much money. I can replace surrounds, cones, even coils, have you done any of that before?

They are NOT glued, get thee a narrow putty knife, say 1" wide, carefully tap around the edges, (protecting wood at edges, perhaps put tape around the driver before getting them out).

they will eventually come out. Hook up any cheap speaker to the wires to the woofer, shows if signal is coming out of the crossover.

Either Madisound or Parts Express have knowledgeable recommendations for replacement woofers/drivers.

Specs, range of frequency performance, crossover points, speaker sensitivity, ____ ohms (nominal) .... whatever facts you can gather helps find a replacement.

i.e. My old JSE Infinite Slopes have Dual Coil Woofers, special to their performance. My friend simply cannot find dual coil replacements, John Sollecito (the JS in JSE) cannot find a replacement woofer) my friend went with Parts Express recommendation. Then found another pair, great price, original dual coil woofers. His pair with replacement single coil both sound and measure like the dual coil. I’m sure Modafferi had his reasons relative to his patent,

but ....

Dynaxox and HiVi have both knocked off this style of Dynaudio woofer. Both spec similarly to the Dyn’s

@audioman58 makes a good point, if there isn't any sound coming from the woofers it could be a crossover issue which would be far less expensive to repair then a driver replacement.  The OEM drivers are pricey, they are built to last so it wouldnt surprise me at all if it was the crossover.  Mine looked new, even the rubber surrounds show very little signs of age.
