    Yes, they will fit. With room to spare. When I was drawing
    up the initial cabinets in sketchup, I duplicated the box &
    set two of these cabinets side by side. Because of the shape,
    I can reduce the width storage requirement by offsetting the
    cabinets just a little and then sliding them into each other.
    When I do this, they fit into the rear deck with no problems.

    I hope to have them ready for Dakota next year. ;)

      Re: Linehopper: An Esoteric build

      I think your 'baseline reference' needs stated here. The top corner angle to me looks closer to 80 degrees. If your reference is 'from 90 degrees', then it makes more sense.

      Otherwise- that is a neato little measuring stick....

        Thanks for pointing that out, Wolf. The angles are probably
        a little confusing because they are the actual angle that the
        miter saw must be set to when making the cut. The measuring
        device that I used is called a miter protractor
        (Star***t model 505P-7) and it is designed to take a direct
        reading of the angle it is measuring so that I can transfer
        the measurement directly to my compound miter saw.

        The miter protractor has two circular scales. The inside
        scale is used for miter cuts and the outside scale is used
        for single cuts.

        The top corner angle is 79 degrees visually, but I set my miter
        saw bevel to 11 degrees to cut the two panels that make up this
        joint because this is the angle that my miter protractor tells
        me to use.

          That's a cool little tool. Actually looks reasonably priced too - I might snag one or put it on the Christmas list.

            Linehopper is beginning to take shape:

              After gluing up the top and three rear panels, I removed
              the temporary center alignment box from each speaker:

                  How are planning to line up the edges of the panel with one another? Do you plan to have the edges angled? This always seems pretty daunting to me.
                  -Ani
                  I beveled the two short edges of the front, top, and back panels using my 12" dual bevel sliding compound miter saw. I determined the amount of bevel needed by using a measurement tool called a miter protractor.

                      I glued up the bottom front panel this morning & removed
                      the last temporary alignment box. Linehopper is now 100%
                      self-supporting!

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.

                        Thanks for the tip Paul,

                        I checked with a couple local suppliers about granite
                        bases. They estimated 1.25" granite at roughly 18 to
                        22 lbs per square foot. Two 12x24" bases would weigh
                        roughly 40 lbs each. This would make the total speaker
                        approximately 85 lbs.

                        They will cut up to four 3/8" faucet holes free of charge.
                        A standard edge treatment is free, but if I want a custom
                        edge, the cost goes up significantly.

                        In terms of overall cost, well, lets just say this: I
                        could buy a pretty good pair of high end tweeters for the
                        cost of two small 12x24 bases! Granite is not cheap!

                        I would also like to keep the weight of the base at about
                        20 lbs so that the total speaker would be about 65 lbs. I
                        calculated that a 12x26x1.5" MDF base sandwich would weigh
                        about 13 pounds. I could then add three 3/16x2x24" steel
                        bar stock strips glued into the routed out center of this
                        base to increase the weight to 20 lbs. How does that sound?
                        Much cheaper and easier to lift in & out of my car.

                              My suggestion was made primarily because of the high density of granite and that it is very attractive in appearance, not that it was particularly thrifty. Your idea sounds very good but you might consider locating those steel bars towards the back of the base in order to counter the apparent "tipping forward" tendency of the speaker cabinet as a whole. In the end, you need to do what you think is best and I whole heartedly understand not wanting these to weigh so much you have trouble moving them around by yourself.

                              edge, the cost goes up significantly.

                              In terms of overall cost, well, lets just say this: I
                              could buy a pretty good pair of high end tweeters for the
                              cost of two small 12x24 bases! Granite is not cheap!

                              I would also like to keep the weight of the base at about
                              20 lbs so that the total speaker would be about 65 lbs. I
                              calculated that a 12x26x1.5" MDF base sandwich would weigh
                              about 13 pounds. I could then add three 3/16x2x24" steel
                              bar stock strips glued into the routed out center of this
                              base to increase the weight to 20 lbs. How does that sound?
                              Much cheaper and easier to lift in & out of my car.

                                I didn't permanently attach the granite bases to my mains, just drilled the holes, added threaded rod covered in a couple layers of heatshrink tubing sticking out of the feet, then set the enclosures on top of the granite.


                                The length and clearance between the "posts" and the holes in the granite allow it not to tilt out of the bases therefor keeping it from falling over. Just a thought...
