playntheblues Posted April 18, 2005 Author Share Posted April 18, 2005 Hey Sunnysal, I still have them it will be one week this Thursday. They do a lot of things great. However to me they dont sound as open as the K-horn. And of course there is nothing below 40 Hz or so. I am tempted to try there top of the line speaker the Definition. I have also been looking at Salksounds HT3 but the efficiency is only 85 db dont think I could get use to that. Plus it would require new amps. The K-horn has spoiled me, dont know what to replace it with? I may wait another year before moving to the lake. I may also have to find a home or build one that can accommodate the MIGHTY K-HORN, LOL Quote Link to comment Share on other sites More sharing options...
sunnysal Posted April 18, 2005 Share Posted April 18, 2005 What to replace Klipschorns? Cornwalls or Belles. Those are too big? then you might want to try adding a powered subwoofer to the single driver speaker. Tony Quote Link to comment Share on other sites More sharing options...

JohnA Posted April 19, 2005 Share Posted April 19, 2005 I don't believe 101 dB and 40 Hz out of a 10" woofer. If it can be done, it would have high excursion and high distortion. At 85 to 89 dB it becomes believeable. Quote Link to comment Share on other sites More sharing options...
formica Posted April 19, 2005 Share Posted April 19, 2005 I agree... something in those specs just don't jive. It's a regular cabinet and therefore it will follow Hoffman's Iron Law; "Low-frequency capability, box size, and efficiency form the three key aspects of system design. To increase any of the three, you have to give up something from the other two" With that high an efficiency, and such a small box, it's bass response is bound to be similar to a Heresy. Might be a nice speaker with a sub... Rob Quote Link to comment Share on other sites More sharing options...
sunnysal Posted April 19, 2005 Share Posted April 19, 2005 that is why I want to hear something about that low frequency ouput...it may "go" to 40hz, but it must drop precipitously in output below 80hz...tony Quote Link to comment Share on other sites More sharing options...

playntheblues Posted April 20, 2005 Author Share Posted April 20, 2005 I have been listening to the k-horns this week. Just got my Teac 700 in. I will put the Zus back in tonight. You would be very suprised at the eff. I think 101 is right on I get 100db spl with a twenty watt set amp. no problem what so ever and my Transcendent pre amp does not have very much gain! The 10 inch driver does not move a lot. The Cabinet has some special design, it is vented at the bottom and was designed by an automotive guy. I forget what they call it but I think it is along the line of headers on an engine, or the reverse. Here is there quote "The Druid is not a bass reflex design and does not correlate to Helmholtz resonators. While the reactance and impedance plot may look similar to those of a ported design, such measures cannot be specifically correlated to enclosure acoustics. Without divulging the proprietary math and correlations, let me outline a few principles expressed in the Druid and contrast them with bass reflex (ported) designs. A bass reflex loudspeaker uses a simple Helmoltz resonator to augment lower frequencies and control cone motion. A Helmoltz resonator consists of a rigid-walled cavity (the volume) with a neck (port) with an area and length. The fluid (air) moves as a unit to provide the mass element and if the quarter wavelength is much greater than volume, the acoustic pressure within the loudspeaker box provides the stiffness element; the resistive element is provided by the opening that radiates the simple source sound. All Helmoltz resonators contain these basic elements. The Druid enclosure is expressed, on a fundamental level, like that of a waveguide with uniform cross section and terminated and driven at one end. Propagation within the Druid is mostly planer and standing waves are not stimulated. Power radiation from the open end is expressed similarly to that of a standard open-ended pipe, driven and terminated from the opposing end. Though similar, the Druid cannot be fully defined by waveguide, loudspeaker transmission line or driven pipe models. Development of an acoustical model accounting for driver introduced dynamic variables and resulting model changes revealed areas of non planer propagation. The resulting turbulence is wavelength relational and proportional to amplitude. Applied to loudspeaker design, the new Griewe model shows resulting noise distortions, in varying degrees, throughout the entire audible range. Modifications within and to an audio waveguide that improve loudspeaker are proprietary, the basic idea being to minimize or eliminate non-planer oscillatory propagation. The enclosure acoustic design principles used in the Druid are based on Ron Griewes research and resulting patents. Ron has granted Sean Casey permission to use his research and collaborated on the fundamental application to loudspeakers. Ron Griewe was the editor and chief of Cycle World magazine for fourteen years and has worked as an engineer for several motorcycle manufacturing companies."

TBrennan Posted April 20, 2005 Share Posted April 20, 2005 So it's a glasspack speaker? Smittys? They gonna sell them in the JC Whitney catalog? Quote Link to comment Share on other sites More sharing options...
sunnysal Posted April 20, 2005 Share Posted April 20, 2005 wierd! it looks like he is trying to relate a port to a helmholtz resonator, if he is you can write him off...they are entirely different things...the only thing they have in common is that ports and helmholtz resonators are often fabricated from tubes...they do entirely different things and have one big difference: a port has both ends open a helmholtz resonator has only one end open. the helmholtz resonator acts as a filter and is sometimes used in speakers much like a notch filter in the crossover, a narrow one at that! I do not think I need to explain what a port is intended to do but it has NOTHING to do with helmhotz...regards, tony Quote Link to comment Share on other sites More sharing options...
playntheblues Posted April 20, 2005 Author Share Posted April 20, 2005 Well, I hooked them up tonight and listened to them for about 4 more hours. I'm not very good at telling you where exactly 40hz, 60 or 80 hz begins or ends without any measuring equipment, but I would say the speakers are excellant on the top end. My guess would be somewhere between 60 and 40hz they die. Quote Link to comment Share on other sites More sharing options...
sunnysal Posted April 20, 2005 Share Posted April 20, 2005 nothing wrong with a single driver speaker that runs 80hz-15khz! I am sure it sounds quite good (wish I could audition one!) what gets my dander up is when designers make all sorts of wild claims, why can´t they be happy with touting the speaker´s strong points WITHOUT exageration? oh well, I guess it is all part of the high-end audio mystique. regards, tony Quote Link to comment Share on other sites More sharing options...
playntheblues Posted April 21, 2005 Author Share Posted April 21, 2005 And to take that a step further Sal, its a red flag when you read stuff like "Without divulging the proprietary math and correlations,". Although I respect the fact that their R and D cost them a lot of time and money. It reminds me of the wizard of Oz " NEVER MIND THAT MAN BEHING THE CURTAIN" Quote Link to comment Share on other sites More sharing options...
r.cherry Posted April 21, 2005 Share Posted April 21, 2005 please help me here...i thought that you said you were moving and space was going to be a problem. i didn't think you said you had found some new fangled whiz bang speakerz so out go the khorns. i am sure you and most people that can hear would never try to tell you with a straight face these would be able to compete with your khorns. but, if space requirements deem it necessary to downsize the units then why would corns be so much better those aren't small speakers. tell you what, i have a pair of radio shak speakers that are about 4 inches tall 3 inches wide and 3 inches deep, they sound just like khorns so if you want to trade i am willing to find a spot for you khorns. good luck finding a replacement for the best speakers ever made. it's gonna be hard.

sunnysal Posted April 21, 2005 Share Posted April 21, 2005 he probably has the "nipple balls" behind the curtain! don´t ask me what he does with them! tony Quote Link to comment Share on other sites More sharing options...
