  • Open Baffle/"dipole" Build

    I love seeing build threads, and I know I will have questions for the electronic experts as I get closer to finishing.... so, I'm posting these to inspire any experts to answer any "newbie" questions should they arise. I'm also putting them up for those, like myself, who just like to see stuff built.

    This is an ORION clone/ripoff. My ending goal turned out to be a speaker that could rival or contend with the ORION for under $1200. I don't think they'll sound as good or better, but for the money, I hope they are a much better value with similar sound quality.
    To make the woofer frame/baffle, I chose a self developed "Z-frame." No, I have no Idea how it will sound, but the crossover is active.

    I assume you're going the opposing-woofer route?

      Then I measured and marked a MTM(mid-tweeter-mid) outline that would fit on the remaining top part of the speaker.
      I have to mount the tweeter overlapping the mid-woofers, because of the non existent surface area that is needed.

      Here is a pic during the routing:

      I got lucky; the hole for the mid woofers was exact. It is 8.75" diameter for the outer circle and 7.25 for the hole cutout.

        Yes. I hope it will sound alright; It will be unmounted to the top part of the speaker, so if it sounds like a*s, I'll build one with a different design.

          Before the holes were cut, I took these pics to inspire me to finish in a timely manner. This is all I have so far, but I'll keep it updated as I move along with the build.

            I may have missed it, but what drivers are you using for bass? Is it all four hi-vi?

            Thanks, and please keep us updated on your progress.

              probably gonna have some nasty diffraction issues mounting the tweeter on top like that, though.

                  Very nice looking speakers. You must be very good with your hands and lots of patient.

                  Do you intend to use passive or active x-over? Any details available yet?

                    "It has been remarked that if one selects his own components, builds his own enclosure, and is convinced he has made a wise choice of design, then his own loudspeaker sounds better to him than does anyone else's loudspeaker. In this case, the frequency response of the loudspeaker seems to play only a minor part in forming a person's opinion."

                      I'm going to use the Behringer DCX2496 for the crossover.
                      I'll post some updates if I get anything good done this weekend.

                        I use a similar arrangement, quick and effective and more importantly the sound will not disappoint. I am thinking of using passive in the longer term.

                          I got some more work done, and here some of the pics. I'll post more when I have time.

                          I added sides to the front baffle, but they were too big, so I had to make some adjustments.


                          I marked the part to rough-cut.





                          Then I routed them flush.

                            Next, I used the router to put an angle on the edges of the baffle back. I didn't want the piece look like I meant to combine it with the side panel.





                            I used a cheese-grater type of file/rasp to get the end edge but sandpaper works too.

                              your woodworking prowess really makes me wish you were using a nicer 8" midbass .. say, the peerless HDS?
