    They are looking great with that coffee colored front baffle. I'm sure they will sound great too, I'm hoping we will get to hear these at MWAF...

      Thanks! I might end up having to sand and redye one baffle; a bead of sweat dropped off my forehead while dying them and despite my efforts to take care of it on the front end, it resulted in a slight blotch. Right in the middle of the baffle.. I will re-evaluate it in a couple different lights.

      I do do hope they make it to MWAF. I’m sure they don’t compare sonically to that other builders projects do but it would be nice to get some feedback. I’m also not sure how a large room will affect the bass and OB mid, as I do my measurements and voicing in a finished basement.

          Wow that brown looks excellent - nice job! Can't wait to see with the topcoat on! Are you going gloss or satin?

            Thanks guys. They had a nice semigloss look with just the shellac. Maybe I should have left it, but I lacquered over it for a more durable finish. I plan to go gloss, but there will be some orange peel due to my lack of finishing skills.

              Here is with just the shellac. They looked better than now with the lacquer I think.

                The wood down the side is functional as well as providing visual contrast. There is a layer of green glue between it and the cab to damp cab resonance (in theory at least).

                  Very nice work! I like the accent pieces and especially when they are functional. I suspect the damping layer of Green Glue and extra mass will help a lot.

                    That is a great looking speaker, Dynamo! The wood accent/bracing pieces really add a great design/function element that draws the eye in. I have a pair of old Infinity boxes that are a bit over 2 cubes, that have rotted 10's in them, and this is making me think....

                      Thanks guys. I got the crossover boards stuffed but not soldered or wired yet. One board per driver and the hotter resistors on a heatsink. The plan is external crossovers with a clear top and the heatsink as the front.

                        The external crossover cabinets are loosely assembled. Input via binding posts, output via a speakon interconnect.

                          I got the crossovers 95% finished. I also ran them through dats and listened to them and luckily I somehow managed to wire them right the first time..

                            Starting to make the second coax. Just a bolt and a good whack or two from a hammer from the pole hole and the phase plug pops out.
