Quite possibly the best treatment to repair or refurbish vintage paper cone speakers. Not Poly, PVA, Mod Podge, Silicone or other plastic compounds, that will change the harmonic nature of a paper driver. This is a 100% natural organic formulation used to treat wood and by default paper (wood pulp).
What this is, is a result of 30 years of research, formulation and experimentation to reproduce the varnish used by master luthiers from the golden age of violin and cello building. The best varnishes would not change the natural vibration characteristics of an instrument, only seal and protect the wood. It should remain somewhat elastic for many years.This was always a highly guarded secret. I've used this to refurbish and repair vintage violins and cellos.
The same properties that make this varnish excel in restoring a vintage violin or cello, make this the best substance in refurbishing and strengthening a vintage paper cone driver that has lost it tensile strength due to age, and vibrational shock. Also helps new cones to reach their maximum potential.
This is not an off the shelf product, but a time consuming and labor intensive formulation of multiple natural compounds. Some of the ingredients are getting hard to source. It is expensive to make. This way beyond Dammer Varnish or Shellac.
I have used this many times over the years to repair, refurbish and upgrade paper cone drivers. It works better than any other treatment I've tried. You won't be disappointed in the results.
Used 50/50 with denatured alcohol. Recommend 2 coats on the front, rear and whizzer cone if it has one. One bottle will do a pair of 6.5 inch drivers. If doing 8 inch or larger, you will need 2 bottles.
I will send you application instructions when you purchase.
$25.00 firm plus shipping. Due to compounds used, I can only ship in the USA.
