        omnimic measurement on RAAL @1.2m on axis 1/48th smoothing

        the thing is, i always get dropping response in RAAL, is this omnimic problem?

          z-offset are -0.022 for midrange and -0.09 for 3012LF
          vertical offset are -0.145 for midrange and -0.505 for 3012LF

          im using PCD to create the crossover, this is my first time, so here are my questions :D

          1. Is it correct to use on axis measurement for creating transfer function? assuming if we input the vertical and z-offset the pcd will simulated it?
          2. i got horrible peaks and dips across the response that i dont know which ones i should address it first. the standout hump would be the baffle step around 600-1khz.
          3. im trying to use first order electrical to achieve LR2, this is possible, but again i dont know how to address the dips and peaks.

          any help will be greatly appreciated,

          cheers

            Roman measured a similar high end droop in the RAAL he measured. I believe he took his measurements in SoundEasy.
            Don't listen to me - I have not sold any $150,000 speakers.

              If you want to verify your tweeter, you can send it to me with the return shipping label and I'll measure it on a wide baffle, calibrated mic, Sound Easy. I also have Omni Mic and can check it with mine but usually Omni and SE give very close results with the difference in presentation.
              For shi.ts and giggles I have Raven R1 on hands and permission to publish measurements by the owner. That should be interesting too.
              Henry, can you post graphic files of your responses? I don't have any audio software on my home puter.

                The 70-10D measures very flat. Which test track number did you use?

                  hi rick,

                  i used track 2, mono sine sweep. i think when i measured both speakers in pseudo noise, the highs improve, but i didnt save the graph.

                  hi r-carpenter,
                  here's the snapshot of raal

                      Can you post one of the RAAL from a closer distance and see if the top octave improves?

                        how was this gated and how was the mic position?

                          thanks for chiming in. here's the 20cm RAAL graph, it still looks similar

                            hi r-carpenter,

                            both 3012LF and Satori is on 1.2m distance and 15msec gated.

                              15 mSec is a very long gate time. When you do the sweep look at the impulse and see at what point ripples begin to develop in the impulse response after the initial impulse has settled back to a flat line. These ripples are reflections. Then set you gate time inside the time of the first reflection. This will give you a much cleaner response curve.
