    Well....
    I have had a chance to design, layout and program all of the parts for the enclosures for these.

    Yes, I had definitely thought of that, and would highly recommend it to anyone building this. It just makes for a more refined fit-and-finish. I will say from experience that when you need to flip a piece over when routing holes, it does take some pre-planning, though. (ie: you run the risk of losing your pivot hole if you route all the way though)

    Honestly, sometimes when I do my prototypes I skip some of the "fit and finish" details. Sometimes it's just simply to save time, but other times I do it to prove that "you can still have great-sounding speakers even if you're not a perfectionist woodworker." If someone wants to build my design, I really don't want them to feel intimidated or held-back because they don't have certain tools or skills.

    That's an AWFUL lot of stuffing (maybe too much?).

    Yes. The baffle is a single piece, I may use 18mm mdf board + 2mm solid wood board to stick together, so that the surface will look more textured. Secure it with numerous screws around the panel.

    In fact, I am still indecisive at the moment, and have not yet finalized whether to use a detachable panel. A lot of screws on the panel will also not look so good.

    I saw the forum post last night and I was wondering if it would be better to improve another kind of internal support.
    Quoting images from the forum



    I ordered the speakers from soundimports and they have arrived in my locker after 108,000 miles and he is looking forward to my construction as soon as possible.

    Were you planning on doing a removable baffle?

    I just noticed the 5.0 mH Iron Core inductor is showing up as IN STOCK on PEs website

    Paul Carmody It took me some time to make a structural diagram of the enclosure. I made some changes to the internal bracket. I used two pieces of wood with a width of 36mm to connect the back, lock a screw + glue, and it should be very strong. I adjusted the internal horizontal brackets to the upper and lower edges of the subwoofer. I think the subwoofer will bring more vibration, so I installed the brackets closer to the subwoofer.
    Due to the height of the PVC cap of the midrange speaker, it may touch the vertical bracket wooden bar. We can adjust the position forward and backward by adjusting the 36mm wide wooden bar connection points on the left and right sides. I also added 2 wooden strips on the left and right sides of the back baffle for glue sticking, which should help strengthen the overall back panel.
    I adjusted inches to millimeters. The overall cabinet structure is obtained.
    I upload 3D source file, please help me to check, is the size correct?
    And is my internal support structure reasonable?
    Thanks!

    I used the ones with the flat bottom that you show in the Amazon picture.
Working...
