    Edit: Just had a thought. We both have talked about the stability issue and what you might consider to make it not fall over easily on its face. Granite cutouts from counter-top makers might be worth considering. Granite that's about 1-1/8 or so inches thick weighs about 22 lb/ft2, I believe. I don't know how much a pair of the size you need might cost, especially if the counter-top maker would cut them for you, but that sure would help using them for the bottoms of the cabinets.

    Thanks for the tip. I'll check into the cost from my local suppliers this weekend. That would most certainly solve the tipping issue.

      You'd also have to figure out how to securely attach granite bases to the cabinets' bottoms. Presumably clearance holes through the granite that the counter-top maker would "drill" for bolts or screws into the cabinets. Might be really difficult, though, to come up with anchors in or attached to the cabinets strong enough to hold the weight of the granite.

        Re: Linehopper: An Esoteric build

        Marble and granite countertop makers use epoxy-set anchors usually with machine screws to hold things in place. Fastenal, Hilti, Dewalt stores and even some Home Depots and Lowe's carry the fasteners now. If the HD or Lowe's sells and installs granite countertops, they usually carry the fasteners. The HD nearest me custom makes the countertops as a "DIY" install on their custom cabinets. I'm not sure I'd want to try it on my 79 year-old formerly kitchen/back porch (it isn't square or level and "true" any direction) but then lots of new construction isn't any better!

          Nice work!! Those Esoterics really looks good!

          I have plans to build the TuLines from Paul K, but with the Esoteric drivers instead of the RS180s. What are the crossover frequencies for this setup?

            Granite can be DIY if you want it to be. I have a few pics of my set-ups when I did the bases for my "A Mains" speaker build. I had the granite place cut the bases to size and I did the machining. If you want to get that involved I'll help you out anyway I can.

              Hey Bill,

              I'm very impressed with your cuts from a circular saw.

              And, it couldn't be any other way, the design is just AWESOME!

              Thanks for sharing,
              Gene

                A little progress::

                To keep everything aligned & square, I built an alignment
                fixture consisting of a 24.5x48.5x1.5" MDF platform sitting
                on top of 3 saw horses. I then clamped a total of 9 MDF
                alignment gauges to the platform. To begin the assembly,
                I dropped one of the profile side panels into the fixture,
                which then formed the first layer of my cabinet "sandwich":

                To form the 2nd layer of my "sandwich", I built six small
                alignment boxes (three for each speaker) to hold the side
                profile panels apart by exactly 6.625 inches:

                I placed these temporary alignment boxes at the top, middle,
                and bottom of the profile panel, being careful not to let them
                extend beyond the edges of the profile panel.

                  I completed my "sandwich" by placing another profile side panel
                  on top of the temporary alignment boxes. I adjusted all the
                  panels for best alignment and then clamped the entire "sandwich"
                  together with bar clamps.

                    Here is what the sandwich looks like from a few different
                    angles:

                    I made further adjustments to the side profile panels until
                    they were in perfect alignment, top to bottom. Then I glued
                    a bunch of small MDF blocks onto the temporary boxes to hold
                    the sandwich together without clamps. These small MDF
                    gluing blocks will be punched out later with a hammer when I
                    remove the temporary alignment boxes.

                        The xover of my prototype is 1.8kHz at 12dB/octave. For the final system,
                        it will be somewhere in the 1-2.5kHz range, based on in-cabinet testing & Xsim modeling.

                          I sure hope no glue from these blocks oozed its way onto and around the alignment boxes such that those boxes are also now glued in. :eek:

                            I don't think it will, as I used a very small dab of glue. I was thinking about using 100% silicone
                            sealant instead, but I was afraid that the cabinet would come apart when I removed the clamps.

                              Just joking with you, Bill, as I'm sure you're being very careful, although if I tried the same thing, I might end up with a big OOPS.
