  1. Khornukopia

    My new K-horns setup needs your help.

    Congratulations on your new Klipschorns. Start with #1 on your list.
  2. Some room and speaker combinations work together really well. Unfortunately, I don't have bandwidth suggestions. I use an auto-EQ system. Press a button, let it measure, calculate and adjust.

    1802 sub port experiment

    That is a big subwoofer !!!
  4. The red trace is my La Scala bass bin. The blue trace is a high quality direct radiator speaker box. The measurement mic was in front of a listening position across the room from the two side by side speakers. This was just to see if the "150Hz hump" was something to be seriously concerned with. The hump was there at one meter measuring distance, but it levels out across the room, so I am not worried about it. The dip at 320Hz changes when I move the mic around. Everything measures a little differently when the mic is re-positioned. EQ switched off
  5. The display in the picture is the measurement from a wired microphone connected to a dbx PA2. I also use the free download, REW (Room EQ Wizard) on a laptop. There are some inexpensive or free RTA apps available for Android and I-phone devices that are very handy tools. I like to capture freeze frames of my handheld RTA and SPL meter when listening to live music, so I can make realistic comparisons at home. On your smart phone or I-Pod, just search the app store for RTA and/or SPL meter.
  6. The huge difference is when you turn up the volume. Most of the other speakers can't produce the clean, powerful SPL.
  7. My Klipschorns measure fairly good, and sound bigger and better than another pair of speakers that measure flatter, in the same room.
  8. @kink56 , I played some full spectrum pink noise through a La Scala while observing a Real Time Analyzer and I see the hump in the frequency response that you are talking about. I guess that gives this speaker the "punch" that many people seem to enjoy. Thanks for giving me something interesting to think about.
  9. I like to think he is OK here. We are all discussing audio equipment and loudspeakers and learning from each other. I appreciate everyone's comments, because I gain a bit of knowledge from everything I read.
  10. Maybe he did not realize it was a bad recording. It could just be a song he likes, and that it emphasizes something he can hear, but others can not, in certain speaker designs. (Am I allowed to be apologetic for both sides of a conversation?)
  11. @kink56 , I notice that you are in Tucson. Maybe the wood panels of your Belle cabinets had dried out in the arid climate. The plywood on my old La Scala cabinet did not seem as dense as other newer cabinets, so I glued and screwed extra panel thickness to the sides before wrapping them with veneer.
  12. I was just commenting on the #1 recording you play when you conduct a speaker demonstration, and you suggested that we listen to. I also think that your comments about the hump are valid, but the recording of the song is not the best choice for the demo, unless the point is to make the speaker sound unnaturally bad.
  13. The background, or underground rumble on that recording caused the original recording to distort. Then when it is played back, the sub-sonic rumble forces the woofers to overwork, even if you can not hear it, causing intermodulation distortion which compounds the problem by creating another abnormal level of distortion. This may be worse than the above described condition, which I presume would be a clean recording.

    Garage speakers

    I meet the nicest people when I go listen to music. A picture of symphony hall from our seats on front row center. The orchestra played the theme music from Star Wars. It was amazing.
  15. Actually, it is a clever way to make any piece of audio equipment sound bad.
