  • Re: sony buyout

    I thought a case was 24 as well. I ordered 48 thinking I was ordering 2 cases.

      basic measurements.
      I couldn't do distortions and waterfall today because my neighbor was running thickness planer all day. So these will come next week some time.
      Calibrated mic as well.

          1 meter away, 6msc gating. My baffle is a 4x8 and the driver is at 1.65m high from the floor (nearest boundary in this case)

            aaand merged response (at 500hz)
            diffraction is not added
            The SPL is adjusted for 2.83v so it can be taken as absolute.

                I just thought about the number of layers and realized my error, came scurrying back to make a correction -- but too late. Made the correction anyway. 24 per case, i.e., two layers of 12 is correct.

                Thanks for noticing...

                  Whew....With their thin frames I was worried about the frames getting bent if shipped individually outside the case.

                    Sweet!

                    When can I get a .frd and .zma file to start designing a crossover? I need to order 2 more cases of these, since I'm using one up for the line array and I need more for the TM speakers I'll be designing.

                      on Monday I guess. My computer is at work.
                      How do I produce .frd or zma in Sound Easy? Export as.......... I have to look in to that.
                      So, what do you think, Tank it on the top end and may be that's enough?
                      Raised response below 200hz worries me a bit.
                      ringing at 5k is just a cone resonance. I'll look a bit more in to frame improvements after CSDs next week.

                        Nevermind on the .zma. I just remembered my WT3 can get those files as well. I've uploaded the .zma file I just took from one of these. I had to rename the extension to .txt in order to add it as an attachment, so you'll have to change the file extension in order to use it.

                        Looks like there may not be a way to export the .frd. However, I might be able to trace one of the response images you posted.

                          I'll work in Sound Easy myself but here, looks like JohnK already answered my question. I'll get the file for you next week.

                            Yep, I looked through that as well. I'm actually in the process of tracing it myself. Any chance you could upload a higher resolution image of the frequency response?

                              PE compresses files. Images that I have are a bit bigger.

                                Thanks, but I managed to play around with the settings some on that image to darken up the line and use SPL Copy to run past it.

                                I've uploaded the .frd file, again with the extension renamed to a txt.

                                If anyone needs them, I also have the .zma and .frd for the tweeter.
