You mean there's more to HiFi than a LP12?

Care and Feeding of High Fidelity Speakers

Post by LD100 » Fri Mar 29, 2019 6:45 pm

Just curious what, if any, maintenance regime people follow for their priceless old speakers? :smt017

I had been using a automotive treatment for rubber parts on cars for my rubber speaker surrounds and polyproplene cones.
Lately my favorite is 303 Aerospace Protectant.

Of course, protecting the wood is a must, my current favorite for wood is Lord Sheraton Caretaker Wood Balsam.
Just be sure to have adequate ventilation. xss35

Seeing is believing, and after over 40 years, I think they might even sound better when properly maintained (and fully broken in). :lol:

Does the wood balsam leave, or result in, a gloss finish? I have a pair of Rogers LS7 which have been cleaned with spray polish containing beeswax 🐝. This has resulted in a gloss finish, so I’ve never polished or treated my NBLs for fear of the same.

It’s impossible to access the bass drivers on the NBL, so the rubber surround couldn’t be treated in any way. I just fear the day when they fail in some way. But then that would mean I could investigate something else :)

No, but the balsam I use is a paste, my understanding is that manufacturers need to use additives for spray polishes so that the wax comes out. The additives may have contributed to your problem of gloss.
Here is a photo using a flash, the color of the rosewood shows up much lighter, but no gloss. I also use this balsam on my LP12 plinth...no gloss, just the nice natural finish and all the corner edges are nice and tight after 40+ years. :smt023
