    Oh no, not again

    FIFY.

    Of course, the Orion has anything but a smooth, linearly decreasing off axis (flares at/above 1/3 WL of both pistons), so it is a poor example for a generalization. The Pluto OTOH, does have a smooth, linearly decreasing off axis. The same universal HF shelving filter for it, is where???

      I can see how that disability would pose a problem, AJ, both for this lecture and pursuing an audio hobby in general. More power to you for trying . . .

      If a transcript becomes available I'll send you a link . . .

        Agreed.

        cheers,

          Well . . . perhaps . . . but it doesn't seem to have helped you understand what Linkwitz said. And you may still be missing some subtle . . . details . . . of what speakers really sound like.

          Just sayin . . .

          I can't help you with that, of course, but I will still send a transcript (of the presentation) if one appears . . .

              You know, it's fairly obvious that what AJ posted concerning the actual measured responses of the Orion and Pluto, is in stark contrast to the words you posted to open this thread.

              Being that the case is now laid out before us, I submit that it is your opening assertions that need refinement, not AJs display of actual data concerning the systems that SL produced himself.

                  I disagree with Linkwitz, making me a dimwit, or perhaps brilliant?

                  Who knows! But I think rolled off speakers sound very poor, even if god himself farted them out of his own bum.

                  I have my explanations as well, all have to do with actual sounds and their existence in the real world, and why a 5KHz cymbal crash sounds nothing like a 5KHz piccilo note, but I will save the flames and end it at that. :rolleyes:

                    Well at least you listened to the presentation, and have some answer to his theories about HRTF and phantom image formation . . . which puts you ahead of AJ and Pete, right?

                    Right ? ? ?

                      And to keep it OnT, the acoustical enegery at HF is weak at best. In theory, it needs to actully be slight elevated above 12K or so just to get to your ears with any authority, regardless of beaming, etc.

                        I consider modern mastering very bright. A "flat" speaker comes through extremely sibilant on produced music, so I agree.

                        On the other hand I believe for live sound, an extra bit of brightness for FOH speakers is welcomed (as long as they still have a strong mid range). Raw instrument sources do not have anywhere near the presence of a final mastered album and have extra bass from proximity effect (as everything is generally close miked). Of course EQ comes in to play but not typically anywhere near the level of mixing/mastering in a studio.

                          You are correct, but that's not what Linkwitz is talking about. He is addressing an interesting consequence of attempting to produce a full left-to-right (phantom) acoustic image from two loudspeakers . . .

                          It's worth a listen . . . he covers a lot of ground.

                            Lol, glad you could tell I didn't listen to it. I didn't, I posted pre-maturely. I don't have a free hour and a half tonight. I'll give it a listen through later on.

                              I just listened to the presentation in ZilchLab. It sounded good over EconoWaves. ;)

                              I agree with many of the concepts expressed, however it doesn't yet appear he gets that he is taliking about power response, and I have serious doubts that any one curve may be prescribed as "optimum."

                              We are once again on the same page with respect to the importance of controlled directivity, but he contradicts himself when stating that the ideal source is omni, and like a bare light bulb, should illuminate the entire room.

                              I also note that he is now prescribing a diffuse front wall to mitigate direct reflections from that direction, and they do not appear in his ray diagram slide. That may have been the case all along, and I am only just now recognizing it, tho.
