JBL 4311 Value

Spackling is worthless as a speaker repair product, unless used on the cabinet. And even then there are better products to use.
Spackle is useful for some wall repairs.
Do you know what Aquaplas is made of? It was sprayed onto the cone to add mass. It cracks easily. I don't know and perhaps it was a trade secret, but certainly repairing it is unique to mending torn paper cones, for example.

BTW, I didn't suggest that it was the choice of product, only that I suspected it was better than the rubber cement someone used on mine.
 
Also, if the woofers are as close to the floor as they appear to be in the pics, the cabinets should be flipped to get them on the bottom.

JBL didn't think so as evidenced by the writing, but since they were studio monitors they likely were often on a desk or a flown shelf.

No idea what aquaplas is. Do you mean aquaplas or aquaplast?
Being a tradesman, a painter for 33 years I've had lots of experience with spackle.
Or at least the spackle that comes in plastic jars and is used to repair walls and ceilings.

Maybe there is some other spackle I am not aware of.

Spackling paste or spackling compound is made of gypsum powder and binders and is used to patch small holes, cracks and other imperfections like dents in drywall, plaster walls, and sometimes in wood.
Or this..
In the United States, spackling paste is a putty used to fill holes, small cracks, and other minor surface defects in wood, drywall, and plaster. Typically, spackling is composed of gypsum plaster from hydrated calcium sulfate and glue.

And this...
Definition of Spackle
Spackle is a paste or putty type of product used for sealing or filling the holes or cracks arising out of the wall, wood, and plaster.

Fundamentally I don't think Aquaplas and spackle are the same product based on the ingredients used to make each product.

I’ve had several vintage JBLs with aquaplas, white and black, have inspected very closely and never has there been any cracking on them. One pair of L100As I bought used and they were rather abused, but still excellent cones w/o cracks (just beverage spills).

I don’t agree that simple age and normal use will crack aquaplas.
 
I'm saying aquaplas is NOT the spackle that I use in my line of work.
I've cut and pasted a couple definitions of spackle already.
Have you compared the ingredients used in each product?
I would not use spackle for any speaker repair outside of the cabinets. And there are better products for that.

I'm done.
Enjoy your aquaplas.:)

That's not what I said.

If I misconstrued your comment as aquaplas and spackle are the same then my apologies.
Every so often my reading comprehension takes a day off.

Not a one for one example but I sold a VGC pair of JBL L36 Decades with MINT drivers for $310 and only had 1 caller. He was a collector and I saw them for resale 6 months later for the same price.

No problem. I can see how it could be misconstrued. I wasn't saying that Aquaplas and spackle are the same thing. I was saying that without knowing what Aquaplas is it would be difficult to know what is or isn't a good patching material for it.
