    • Don't worry   Had never used it myself, but applied it to boxes I made for my K-510 horns.  2 coats ... came out flawless   ... 10 times easier than "painting"
    • I think you mean "you're".
    • Heard achy-breaky a few times long ago but it was on a tv show.... It does not count!
    • Here is all you need to know about Miley Cyrus. She split with her husband of 11 months a week ago and went to Italy with a girlfriend to console her. Great pics of the two making out by the pool. I bet her parents are some proud. I must say I did enjoy the pics   https://www.etonline.com/miley-cyrus-spotted-kissing-brody-jenners-ex-kaitlynn-carter-in-italy-see-the-pda-packed-pics
    • I’ll panic for sure! I’m a first time duratex user . Thanks for the water tip!
    • If using their sponge roller (recommended) you can add water to the duratex to reduce the texture. The thinner you make it the smoother it will go on. Test it out first, doesn't take much water to alter. You can increase the texture on subsequent applications by dialing back on the water added.Don't panic if the first coat isn't pretty. 
    • i’m very proud to report that i have NEVER heard Miley Cyrus and couldn’t even name one of her songs. Funny thing, years ago, i saw a tv show called Rock Star INXS, where they were looking for a new singer. One episode, they gave this guy a Britney Spears song that he had to perform. He was allowed to make changes to the song.  I was watching with my wife and daughters and i was a bit embarrassed to tell them that i liked this guy’s version of the song. Then Dave Navarro (the host) basically said the same thing ... he said he loved it. oh yeah, that’s the only Britney Spears song that i’m aware of too.    
    • Do you really think so? I would like to see the math. One things for certain the line from the dam won't fuse at 3 amperes.
    • One of the great missing links to the loudspeaker engineering repertoire (IMO) is a ranking of loudspeaker performance attributes by measurement type--not based on someone's opinion of what is important, but rather by subjective preference by listener groups on particular loudspeaker types (by listening group preferences), and then an analysis of how the most preferred loudspeakers actually performed, i.e., an approach that is reversed from the engineering literature on loudspeaker measurements.    The following loudspeaker capabilities types are presented from a notable writer on this subject--Joseph D'Appolito (author of Testing Loudspeakers (1998, Audio Amateur Press) an excellent resource for learning about these measurements and what they mean), based on "30 years of designing loudspeakers".  What he didn't mention was that virtually all of these loudspeaker types are direct radiating types, using cone and dome-type drivers in a "monkey coffin" type of small enclosure, with no precedence given within the group: Frequency response Impulse response Cumulative spectral decay Polar response Step response Impedance Efficiency/Sensitivity Distortion Dynamics   Rearranging the above and expanding the list to include some missing measurements, the following list of revealed capabilities based on the Khorn's performance in each of the measured areas:   Full-range directivity (particularly below 800 Hz) Modulation Distortion Compression Distortion Efficiency/Sensitivity Cumulative spectral decay (especially below 800 Hz) Room dimensions/loudspeaker placement Near-field room absorption around loudspeakers   The following list of loudspeaker capabilities are significantly depreciated with regard to those preferring the Khorn's sound reproduction:   Frequency response flatness (particularly below 200 Hz) Impulse response Input Electrical Impedance ___________________________________________________________________________ Each of the above seven capabilities have associated measurements: Directivity -- measured via multiple upsweeps with microphone at a set radial distance from centerline of loudspeaker, usually in 10-15 degree lateral and vertical increments, combined into a "polar spectrogram" view, i.e.,   2. Modulation distortion -- measured via dual-tone test, looking at the relative amplitude of the sideband spikes around 450 Hz in this instance:     3. Compression distortion -- measured via multiple on-axis upsweeps at increasing SPL (trace arithmetic 75 dB [blue trace] overlaid on 100 dB [red]):     4. Efficiency/Sensitivity -- measured by calibrated output to a given calibrated input power or voltage level (looks just like an on-axis SPL/frequency plot)   5. Cumulative Spectral Decay -- measured via Energy-Time Curve (ETC) plot (which also shows room acoustics performance):     6. Room Acoustics/Loudspeaker Placement -- measured by waterfall plot:     7. Near-field room absorption around loudspeakers -- measured early decay time (EDT):     The point to showing these example plots is that the real measurements that make a difference to those people that prefer the sound of Khorns and other Heritage Klipsch loudspeakers--aren't found in Mr. Atkinson's measurements for his magazine.  In effect, he's saying "one size fits all, and my measurements are important, but the ones that you want to see, well, good luck...I'm not going to post that data".  So the value of the magazine review is, in effect, zero--because the people setting up the loudspeakers in their selected room (which apparently was a poor room to use as an example for a good installation of Khorns) and the measurements that the technical editor wants to post...simply do not represent what you need to see and hear if you were a prospective Khorn buyer.  The entire article is a waste of everyone's time.   Chris
