Another difference: the exit of the comp. driver in the Bullfrog Active is 1.5", instead of 1.4" as with the regular CX15N351.

Anybody tried any of the new super slick spray coatings used on race cars, etc., on horns?

You mean mounting the horn in a stuffed enclosure? I thinks that's a wise thing to do, especially with metal and plastic horns. For TAD, Arai Yuichi, Vitavox and similar wood horns, it's not a necessity.


Is this, or this the type of coating you refer to?

Yes, a damping/mass loading box is one way, but I've been exposed to a number of DIY wood horns that had too high an Fs, though none you listed except some metal Vitavox that did, so obviously can't comment on them specifically.

I want to paint mine black. What should I do with the exterior of the horn? Plasti-dip?

Speaking of black, apparently a German got fed up with his historic horn system:
Western Electric Horn 16a, 2x 555a, 2x 594a, 2x Amplifier WE46c.

The first time ever I see original WE gear for sale in Europe.
Asking price is €140.000.

The left horn below needs damping, the horns on the right not necessarily, which would also be rather ridiculous at £4500 each.

Years ago, I saw a pair of original (metal) CN157 horns for sale, including drivers (not the S2 shown).
The seller didn't know what he was dumping and I was primarily fascinated by the faded Vitavox logos that were barely visible in the horn mouths, so I agreed on €25.
Then someone else saw the ad and outbade me, before I could pick 'em up.

Wooden horns made by Martion, the non-wood version and another peek inside the older Bullfrog cabinet.

Interesting stuff! It looks like the cabinets might have a pre-tensioning device.

On the same German ebay site on which the WE stuff is offered, several G.I.P. and Line Magnetic items are for sale... but not a single Martion product (which is German).
