  • Bonsai Accuton Tower Speakers

    This is a build my father just finished up. I gave some minor help, mostly in designing overlays and cosmetic choices. He did all of the building and driver selection. These use an Accuton cell tweeter, Accuton cell mid, and ceramic sandwich woofer. The speakers are actually two separate finished boxes, with the woofer being independent from the mid and tweeter. These use a 3-way active analog xkitz crossover and three stereo parasound amplifiers. Unlike our last two builds, this is a traditional box and not translam. These drivers blend very well together. The highlight is probably the clarity in the mids and effortless clean bass. The top boxes are sealed while the bass boxes are rear-ported. I am happy to answer questions to the best of my ability.

    I was impressed with the seams on the veneer until I saw the actual Bonsai tree on the bottom, yikes! They're beautiful!!! I'm guessing that's a lot of tedious cutting with an x-acto knife?
    Nice work!

      tomzarbo The walnut on the top and front are all overlayed on top of the maple, so it stands proud of the maple. All of those overlays were cut on a laser, so much less tedious and less skill involved to make them perfectly symmetrical. Thanks!

        The curly maple and the walnut look fantastic together. Very well done.
        Is that an 8" woofer?

              I can't show this thread to my wife, she'll ask why I can't replicate these. Incredibly good looking, and I'm sure sounding as well.

                    Beautiful! Thanks for the photos. I need access to CNC, lasers, and 3D printers for good measure. Sent from my SM-G960U using Tapatalk

                      Beautiful speakers. I've been thinking about joining a local maker space where I would have access to CNC, lasers, 3D printers and other large wood working machine just to up my game a little.

                        Me too! Have a great one in Columbus, just haven't justified the membership fee given a realistic estimate of how much time I could actually spend there.

                          Wow, just beautiful. Well done.
                          I really like the way you tied in the tiger (curly?) maple front with the tops.

                            Yep, I'm afraid it will be like my gym membership, $600 for 3 hours of work outs in a year. lol
