One of our bigest projects to date and what a learning expeince. First time dealing with mdf. The base is birch plywood trimmed with brazillian cherry. Might have went a little big on the base size, but hey you wont knock these things over. The plywood got very close to sanding thru even though it was barely sanded . A consequence of this was it blotched terribly with the intended burgandy stain. Despite all the fair warnings online we resorted to polyshades (poly with stain) to cover it up. Turned out okay. The other big mistake was rolling on the gloss black enamel. We thought the ultra smooth roller would be okay, it wasn’t. The speaker mounting screws are one of the more demanding aspects of the job..very little room for error as the recessed cavity is super tight.
Parts express had the plans Online. This is the ‘tall boy’ transmission line with the port in front (Seems like everyone builds the rear port version). These things are crazy heavy. 1 sheet of .75inch mdf, half a sheet of plywood, plus several more pounds in components, feet etc. We opted to mount the crossover in the open part of the back…semi exsposed one a piece of lexan. i like how that turned out. The grills are also homemade. Neomydium magnets embeded in the front baffel. Pine frame that was wrapped with a thin black cotton fabric. played around with available material and this seemed to impede air flow the least.
They sound great! even though they are still in the break in period. probably have $250 to $270 in it, with half of that being the electronics. Still need to wax and polish everything. About half way through we were really getting impatient with wanting to hear and play with these. Thank you experienced speaker builders here who answered questions and provided support on the project’s blog.
