Compressed air powered car $2 a tank possible 1,000 mile range
thirdeye replied to seti's topic in General Klipsch Info
What if your in an accident and this highly compressed tank blows up??? -
Brac , I was simply illustrating in the smearing to some klipsch speakers that are being sealed off in the main cabinet by a thin plastic horn sharing the air volume internally, however as for the external plastic K-horns, well thats another story.. The old Metal K-horns could be better damped maybe, I have not heard it so I can't comment. New plastic K-horns, probably not that beneficial, but this all comes down to the cabinet design of the different klipsch speakers in my opinion.. I mean any that have cheap plastic horn bodys being inside the cabinet absorbing the backwaves etc... directly from the woofers might be worth damping is all I am saying.But then again ANY vibration control period even with horns just sitting on top of a very high power cabinet in a corner like K horns maybe could be benefitting from horn damping.. To directly soften the tone of horns I have in the past taken Felt Triangles and applied them to the actual surface which the compression driver fires into with good tamming results as well, but regular damping would not be a good application there, some soft felt might be if your just trying to do like a diffraction lens type thing and smooth them out from Glaring off the hard surface. Actually interesting thing is disconnect your horn and let the woofer play, if its more amplied and adding color by putting your ear by the horn than obviously it is picking up some of the harmonics and amplifying them more than the deader wood cabinet..

#1 The deadening of the horn back makes perfect sense, not because the horn is necessarily ringing but the resonance from the WOOFER and other vibrating devices in the cabinet also enhance the ringing of the material smearing the image.. I just did a project " The Killer KLF 10's " and they sounded very good right off the bat with the new cabinet and crossover design, however I could tell there was a weaker gap coming off the artificial thin and cheaper plastic horns to the cabinet.. I actually dynamated the whole horn and Magnet to kill of simply more Back waves of the Woofer from resonating thru the plastic surface separating and MAss damping the horn even better from the system.. I did this after listening tests of not treating the horn at all, well guess what, the results were pretty good, lowering the mids a little to be fuller and more integrated to the woofers, and also just smoothing out and causing a more dense and complete image. So although the horns Own frequencies and compression driver may not be as effected by damping the back of the horn the rest of the cabinet air space shared by the other drivers is, and it does consolidate the reflections in the cabinet much better in my opinion, and again it sure can't hurt anything if you have cheap stuff laying around to try it! I did it because I had some sheets of this stuff doing nothing from other projects, used it up and glad I did.. Here is the project link, but I did not get pics of the horns after I did the treatment sorry. Just remeber especially in some of the klipsch designs you do have a very large and THIN plastic surface sealing off a large portion of the cabinet as in my example on the link, it can help deaden things up nicely if applied correctly. http://forums.klipsch.com/forums/t/103108.aspx

Yeah the 30's were some monsters, probably would have benefitted greatly from some extra damping and bracing for sure. I found the KLF 10's to be the perfect sized cabinet, cabinet is reasonably short and stout, but big internal volume still.. Anyway its all about the sound, so make them work is what I say now, most klipsch products have the right idea, just gotta do some of your own magic to make them really all they can be, plus piece of mind back then being they were having some definite Q.C. issues, always though Klipsch has been priced right, Heritage series are a bit arguable on new prices of course.
