  • MarkK's Rs22528A as surrounds build thread

    All panels were cut from 1/2" and laminated together to be approx 1" thick. All panels are laminated, I just need to cut braces and am waiting for Mark to confirm the layout dimensions for the baffle.

    uhmmm....These are huge too.
    First though, panels....


    And then there were monster bookshelves. The baffle is on top for reference...

          Any details on crossovers and dimensions? I'm considering a similar project for my surrounds.

          I can't wait to see the finished project!

            The only thing not there are the baffle layout dimensions which are the following -

            The RS225 is centered on the baffle vertically, and the center of the RS225 is 6" above the bottom edge of the baffle.

            The RS28A is offset 3/4" from the vertical centerline (one to the right and one to the left-obvious but lots of folks accidentally forget to mirror one.)

            The RS28A center of the tweeter dome is 3" down from the top of the cabinet.

            The PE baffle is the standard size for 3/4 cu ft non mtm box.

            Hope that all makes sense...

                That's really cool! I've never seen bracing do that before. I wouldn't even think of trying it without a CNC, myself. But I'm pretty lousy with a jigsaw.
                Isn't it about time we started answering rhetorical questions?

                  You don't need a jigsaw to do that, Paul.
                  You can use a router with an edge-guide, a table saw with a dado blade (or regular blade and a chisel), a hand powersaw with a guide, or lots of other options.
                  You could use a jigsaw, but I wouldn't advise it. The blade will swing out a bit as the length of the blade goes, and you won't get as straight of a cut.

                      Thanks Paul! Definitely took some time to do, but no CNC required. As Wolf said, this is how I did it.....

                      Draw it out.
                      Roughly cut out with jigsaw everything but circles, circles cutout with router.
                      Everything cutout with jigsaw then flush trimmed with a straight edge and clamps.
                      Chamfer all cutouts.

                      That's how I did it. Once I got the hang of it, it's actually really quick and easy.

                      Now it is time to route the channels for the bracing to be inset.

                      I wish I had better weather and more time to get things done....

                        Thanks for the read ligs! You certainly don't see materials like that with speaker systems these days!

                            Well, finally back up on this horse. Since I'm not having the surgery on my knee because my insurance told me I'm fat, I'm hoping to have these constructed by next weekend.

                              Not sure what your situation is, but if you need the surgery you should talk to your doc. He/she can appeal the insurance company and will often win.
