NJbob Posted March 21, 2007 Share Posted March 21, 2007 I just picked up and used some stuff called QUIET KOTE - VB1S PRO. From parts express. Its a spray on dampner made for spraying down car wheel wells and firewalls. Well I sprayed down the k55 horn and inside of the cabinet and this stuff works. DEAD, it imeadiatly knocked down the shout and extended ringing... These speakers keep getting better, who says they cant image. i get center sound almost as good as my magenpans with real uncollered bass to boot Quote Link to comment Share on other sites More sharing options...
marems Posted March 21, 2007 Share Posted March 21, 2007 I've got some of that quiet kote as well but I havent used it yet. You say it works great, how much did you use on the horns? Quote Link to comment Share on other sites More sharing options...
freddyi Posted March 21, 2007 Share Posted March 21, 2007 do you think its better than cheap spray-on undercoating? Quote Link to comment Share on other sites More sharing options...
michael hurd Posted March 22, 2007 Share Posted March 22, 2007 Cheap spray on undercoating??? Like the asphalt based stuff?? YUCK. I could not live in the same room as them with it outgassing. Besides there is little mass to asphalt ( tar ), and no real damping characteristics. A better choice would be multiple coats of RV roof membrane coating. No odor after drying. Can be applied by brush. Quote Link to comment Share on other sites More sharing options...
NJbob Posted March 22, 2007 Author Share Posted March 22, 2007 I couldnt campare it to anything, I bought a 20oz can and sprayed it down enough for two speakers with some left over for a second coating of the horns only (Toninght I will add the second coat). It left a thin skin over the horn and inside cabinet. It did have a paint odor for about an hour then went away. Agion I cant copare but I can say it works and I'm happy. $15, I covered my crossover and sprayed away 10 min. Cant beat that. Quote Link to comment Share on other sites More sharing options...
Guest " " Posted March 24, 2007 Share Posted March 24, 2007 I'm going to sell a horn dampening kit on ebay. It's going to consist of a trash bag and a can of spray foam, like the type used for insulation and sold at home depot. You take the trash bag and stuff it in the xover/horn chamber. Then you fill the bag with spray foam. I'ts also helpful in keeping you out of the xover area....so no more tweaking. Quote Link to comment Share on other sites More sharing options...
NJbob Posted March 25, 2007 Author Share Posted March 25, 2007 verry good idea, does the bag fill around the horn over the top Quote Link to comment Share on other sites More sharing options...
pauln Posted March 27, 2007 Share Posted March 27, 2007 I wrap my mid horns with a bath towel. It's not to damp them (although it probably does) but to keep the wires off of the horn 'cause I think they might vibrate from the contact and make a buzz...

meagain Posted March 27, 2007 Share Posted March 27, 2007 NJBob - Do you have a picture of how this looks on the horn? Or, if not too much trouble, can you take one? Quote Link to comment Share on other sites More sharing options...

Islander Posted March 29, 2007 Share Posted March 29, 2007 Ah, finally figured out how to post a picture. It's more complicated than it was before the forum update. Quote Link to comment Share on other sites More sharing options...
Islander Posted March 29, 2007 Share Posted March 29, 2007 So that's Dynamat Xtreme applied to a K400 horn. I first made templates of heavy paper to fit the horn, then cut the Dynamat to match the templates. Scissors work, but you have to use strong soap or solvent to clean them after. Since I added some grille cloth the the inner side of the cabinet (neater looking than attaching it to the outside), I can't be positive that the damping alone made the difference, but those two changes certainly made the La Scalas more pleasant to listen to.

Speedball Posted March 30, 2007 Share Posted March 30, 2007 Obviously it works on the LaScalas but I did use a similer material on my kg4.2's horn and it killed the sound too much so I removed it. Of course it may have been a denser dampening material. Glad you found an improvement that works for ya[Y] Quote Link to comment Share on other sites More sharing options...
