Hey Flip. It's called Duratex here in the US. I get mine from 30 years Audio experience. Featuring Eminence speakers | Speaker Hardware. I also get wholesale prices on speakers from them. Really great service and pricing.

I use a Harbor Freight hopper gun to apply the duratex. Any other questions you have just ask, I would be glad to help you.

Mike

I know a couple of people with Rhino on rack and speaker cabs and as ute liner (tradespeople) with no chipping.

I have used Duratex also.
I also use the same gravity sprayer.

The Rhino lining was the best so far.
Also the one from Auto Zone worked well but both are extremely NON CLEAN UP friendly. IE don't get it on anything!

Been looking for some
different polyurea based paints and also just recently got some cement paint to test out.

Here are the brochures:
1
2
3

I think the brochures are bull****... But u can try their method if u want it's never gonna work.

First, u'll need an air compressor for this, and wil have to paint in 2 coats.

I've used 2 types of guns.

1st coat:
With a (high pressure paint gun?) (sorry, i dont know how u call it in english), its that gun, where the bottle is in the bottom...
I've used a 2mm nozzle, and 6-7 bar pressure, from 25-30 cm distance...

2nd coat
With an underbody coating gun with a nozzle diameter of 8 or 9 mm, (this unerlined information isn't to find in the brochures, and cost me a lot of money.. so appreciate it )

... with 2-3-5 bar pressure, depends on what structure u want.

U can calculate easily with 1,2 L/m2 for the whole work.

I would very much like to see your input parameters for Hornresp.
Also I an very interested in the parallel horn section that is adjacent to the driver. I like how with that extra folded section you have managed to increase the length of the horn and not waste any internal space.
Looks like a compression chamber.

thanks woody for sharing.
as for the 3-pieces braces in page1, did you make them out of solid panel or holed panel?

Nice work there!

Did you measure impedance vs. frequency? The results should indicate whether or not you achieved the 40 Hz tuning.
