Does pin hole in woofer affect sound quality?


Hello. I own a pair of 2nd generation DCM Time Windows. I am the original owner of these incredible loud speakers. I am currently restoring my 1980's era Hi-Fi system, including the Time Windows.  After removing the grill cloth from the speakers, I noticed one of the woofers in one of the speakers has a pin hole in the diaphragm paper. How much will this affect the sound quality and response of this speaker? Should I consider replacing this woofer? Thanks!

Pin hole, not a problem, but:

sounds like you keep your grill cloth on, so cosmetics not a problem. Got a wife, girlfriend, mother? A little nail polish will do it, comes with the tool you need. Like spray paint, a few thin coats not too thick to start. Lay it on it's back so it doesn't drip down the face of the cone while drying.

AGE deterioration? is paper cone still stiff? Is surround good and still springy, strong enough to keep the woofer centered properly? Voice coils can rub on the magnet if not centered.

I have re-coned my woofers from 1958 twice, I am about to check them soon. My old ones are paper cone's with cloth surround. I paid a pro do do it the first time, did it myself the second time.

Kits are available to restore most speakers, far less costly than replacing the woofer. Check on eBay, online, is OEM around?

I would replace them both so they have equal strength to the air.

I also replaced the surround of my vintage SUB, newer foam surround had rotted.
