  1. Considering the fact that this thread is about the development of the K-402 based Full Range Multiple Entry Horn, which may become THE best sounding loudspeaker for accurate, dynamic music reproduction, I want to expound on the statement I made earlier. The La Scala sounds very good outdoors... for casual listening such as a neighborhood block party or while working in the garden. It also sounds very good outdoors, compared to how it sounds when played at high SPLs in a small reverberant listening room.
  2. DrWho, Thanks for providing the above links. The papers were good reading, but I did skip much of chapter 4 with all the equations that I don't plan to use.
  3. It will be interesting to read about your listening impressions of your New Center speaker after you get a chance to take them outdoors. In the past, I have noted that the La Scala sounds very good outdoors.
  4. I have been reading through a lot of specs lately and noticed the following info. The newest Model KPT-MCM-II Cinema speaker brochure specifies the KPT-305-MB now employs a 12" driver operating at a bandwidth of 340 Hz - 1520 Hz.
  5. 38" X 9" Klipschorn bass bin horn mouth, each side X 2, for a total of 38" X 18". It helps me understand the K-402's capability now that I realize how comparatively big it is. Thanks for answering my questions.
  6. So many good speakers to choose from. Each style has its ideal placement and SPL range, which makes it possible for any good speaker to sound more pleasing than some other "better" speaker in that same room. It is always nice to have something that you really like.
  7. Not upset at all, more like impressed. If not for my infatuation with the good looks of my Klipschorns, I might be buying parts for a K-402 full range system already. In the meantime, am wondering why straight axis bass horns of the past needed to be so very much larger? What is it about the Unity/Synergy style and your Klipsch K-402 based full range horn that defies past limitations? Is it the slight flare at the end of a short cone? If one added this flare extension to the exit of a La Scala, K-horn or Jubilee, will it transform into a profoundly superior speaker? Your project now has me thinking about loudspeakers more than I normally do.
  8. Are you saying that a 20" deep conical-tractrix horn with two 15 inch woofers is able to perform equal to, or better than a 55" exponential horn path length Jubilee or K-horn bass bin? Some of us sentimental folded horn proponents may need more time to comprehend the simplicity of this.
  9. Ok, thanks for the guidance. Wow, these improvements to my overall sound are making me want to stay home even more, but I must exercise moderation in all my favorite activities! Here is a picture of my listening room that I posted on another thread last year, for any viewers who had not seen it there.
  10. I opened my DC One editor and applied the settings recommended in the Cello Palette thread. As I understand the instructions, boost and/or cut is adjusted as desired based on personal listening tests, or has someone already suggested re-EQ guidelines to compensate for typical "improperly mastered pop commercial recordings"?
  11. Sad news. Rest in Peace, DaddyDee
  12. This amp works very well for my system, and by displacing a stack of 2 channel amps, allowed me to clear out a bunch of power cords.
  13. My new amp was intended for multi channel surround power, but after listening to several different speakers during its test run period, I realized that this good, clean sounding 9 channel amp is ideal for powering my tri-amped Khorns and tri-amped La Scala.
  14. ​ Chris, It is interesting to read about the corrections your are making to music recordings. I will need to try that someday, but how do you adjust for streaming music like XM radio, Pandora, etc.?
  15. DavidH, Glad to read that you enjoy your speakers. Do you have any pictures to share?
  16. The RTA image on the left is of a 440 Hz test tone. The image on the right is of the sound produced by a piano when pressing the 440 Hz A-4 key. This visual display showing the overtones of a single note from a single musical instrument helps me understand why everything more complex than a test tone sounds better through a properly configured tri-amp system.
  17. This is a better acoustic example, front row center at The Nutcracker Ballet with 30+ musicians performing Tchaikovsky's music in the orchestra pit directly in front of me.
  18. Interesting thread. Now I need to go back to page one and start reading all the links.
  19. I recently read someone's comment about equalizing their frequency response to being "flat" but the sound being sterile or weak. I can't relocate the specific thread to reply, so I will write here that we want the speakers to have a relatively flat response with a Test Tone, but not a flat music playback response. The attached picture is a snapshot of a hand held RTA display during an excellent sounding live music moment. Any other snapshot will be different and unique for that specific instant, but the green line, momentary average curve of this example is a good guideline for a desirable live music reproduction response at your listening position.
