Damping of 2360. Rock guard or underbody seal

[johanwholst]

Im picking up a pair of 2360 to play with over the christmas season. From others experience, these horns will most likely profit a lot from damping, and I am considering what method to use.

Wurth products are readily available here, and I have been looking at the Bitumen based Underbody seal and the Rock guards that is non-bitumen.
I see advantages using rock guard as it gives a paintable surface, but my gut feeling tells me that I will get a thicker coat and better damping with the messy Underbody Seal

Anybody here that have used these products or similar for damping horns?

I suggest playing with the horns a bit before sticking some bitumen. The fiberglass 2360 don't ring much. Unlike, say, my other 2350. ;-)

Dynamat also make a sound deadening bitumen aimed at the car audio sector.

BTW after 3 years, I still love my 2360a. I went back to to 2350 and 2397 for the fun of testing, but returned to the 2360. I love how the sound is distributed and how its source is not pinpointable. Gonna test them soon with a 18" 2240 woofers in replacement of current 15" 2226 woofers, still in a two-way system. I may add some 2405 for UHF.

I'd like to find a set of plastic 2360b though. ;-)

Glad to hear they still make you happy. Im quite excited to try them out and I am aware of the limitations regarding HF extension and will give both 077 and 2404 a shot. I will use them undampened first to get to know them and dial the EQ needen, but I am quite certain that the flimsy glassfibre would benefit from a proper treatment.

Medium and high frequencies don't have enough energy to make these fiberglass horns vibrate. Unless perhaps you play at hyper high volume. ;-)

Hi Lee,
Just a question about your 2360, they do not look like my 2360, do you know why this difference??
Year's production or what??



Hi also like the 2360 ;-)

Well. They look very much like my 2360a

The 2360b is slightly different as it is made out of plastic and they sre two-piece so that it is cheaper to ship.

Ok, I miss this one" I'd like to find a set of plastic 2360b though. ;-)"
Thx for answer

The plastic 2360b is much rarer than the fiberglass 2360a. Good luck in your search.
