Dylanl Posted March 24, 2004 Share Posted March 24, 2004 I just rope caulked my 1 horn what differences should I expect to hear between one speaker with caulk & one without in an A/B comparison? From a quick listen it seems to seperate the music into layers vs. a melting pot of sound. There is a large difference I just can not put my finger on what it truley is. What have any of you found?

TBrennan Posted March 25, 2004 Share Posted March 25, 2004 Some horns are improved by adding damping material and some horns aren't. If improved the improvement will be in tonality, less coloration. Be careful that you aren't just deluding yourself into hearing a difference. And mind that comparing two speakers they NEVER sound identical because where they are in the room effects the sound greatly. Thus a difference you hear comparing speakers might be due to their different places in the room and not because of a mod. Also normal variances in mass produced speakers means that no two are likely to sound identical regardless of room effects. Quote Link to comment Share on other sites More sharing options...
D-MAN Posted March 25, 2004 Share Posted March 25, 2004 Basically, if it needed dampening in the first place, then you would probably hear a improvement in the "clarity". If not, then no harm done. The mid-range horns cannot be "over-dampened" by material applied to the outside of the horn...some people cast their horns in concrete for exactly that reason, to stifle horn wall vibration.

Dylanl Posted March 26, 2004 Author Share Posted March 26, 2004 Thanks, DMAN. So the only thing I can do is help if I get your drift. Is the same true with the tweeters. Quote Link to comment Share on other sites More sharing options...
Frzninvt Posted March 26, 2004 Share Posted March 26, 2004 The horn lens on the tweeter is smaller and is less subseptible to ringing but if you feel compelled you can put some on it to. I just decided to remove the K-400 horn lenses and replace them with the new composite K-401 lens. At $50 each it was an easy choice, I don't have to mess with gobbing stuff all over them they are rigid and have ribs on the outside to eliminate any possible ringing effects.

Dflip Posted March 26, 2004 Share Posted March 26, 2004 I found some rope caulk made the ringing in the midrange squawker less irritating. I tried this on the tweeter and found it dampened the sound too much for my liking. The amount you put between the magnet and the front edge of the horn depends on what you want it to sound like. I use about 2" up from the magnet. Others have put two layers of caulking on the whole horn throat. Experiment and see what you like. The good thing, it just peel right off and isn't very expensive.

shantheklipschfan Posted April 8, 2004 Share Posted April 8, 2004 I didn't use rope caulk but plumbers putty. The result to me was a wider soundstage and clearer midrange. Seems like I hear more magic of the driver instead of the colorations of the horn. Quote Link to comment Share on other sites More sharing options...
