      that QSC waveguide is not symmetrical? It definitely looks non-uniform by the "sheen" in the pic.

      Is this the one in the pic?

        Symmetrical, to the best of my knowledge. We're seeing images of the 4' fluorescent light fixture directly above, looks like.

        [I'll find a stopper and fill one with beer to verify. :p ]

        Yup....

          Yup....
          Excellent.

          D, Rose is going to be ordering one so that he can "duplicate" it in MDF with his RadarCarve machine.

          http://www.radarcarve.net/

          He's attempting a two-way using the RS28F and RS225-4.

          Are you going to be doing an evaluation of that waveguide loaded with the RS28F?

          Do you happen to know the depth of the opening from the front of the flange?

            Still in the queue; we'll be getting the baseline here in this thread.

            Measures 3" exactly.

            • Dayotn PA Drivers?

              Pete or Zilch, any thoughts about using the new Dayton PA drivers in an EconoWave variant? I have yet to fire up Unibox on them but PE is promising a bit deep output, and the cost is very reasonable.

                  These are the ones Zilch. http://www.parts-express.com/wizards...ge+Flash+Panel

                  How would a 15" work with the QSC horn?

                    If the response plot is to be believed, then it would make a great candidate, as would the 18, 12 or 10. They all have reasonable response past 1500Hz, though the 18 would be pushing past the limits of the criteria of constant directivity.

                        Great explanation Zilch. My interest would be the PA255-8 10" and I'd probably want to try it with the D220Ti CD because I want to spend less before I know if I like them (assume they will sound "good enough" to get me to move up).

                        • Re: Flex Your PCD Mettle:

                          I am looking for a high quality 10" driver to match my DE250 and horn combo similar to what is Harebrain already found. One 10" model which recently receives rave reviews is from Parker Audio's Excalibur model. It uses a 10" PSX Poly Cone. Recently I asked the designer where this driver came from, he declined to reveal the secret.

                          Anyone has any idea what this driver comes from? I am interested.

                            Thanks Zilch, That's the info I was looking for. BTW I was referring to the 152i horn.

                              Looking forward to seeing how this comes out. What CD are you using?

                                With the published sensitivity of the PA255-8, the WG loaded RS28F might make an ideal match as well, after baffle step is considered.
