Your speakers and build looks perfect
I want to build the exact same speakers, but with the center, with the walnut veneer and all. It'll be a great match to my set of solid walnut Ohm Walsh speakers, which I'll use for surrounds. If not, I'll build different surrounds and put the Ohms in my office. I digress....
It looks like you have your own cut sheet, was this on purpose? Although no longer listed on DIYSG website, I did notice
used to have the following dimensions for the 1299:
14.75" W x 40" H x 13" D sealed
14.75" W x 52" H x 14" D ported
Does that mean it was possible to get the flat-packs which are 52" high vs. cutting your own MDF? Is there a reason you went the cut route?
I don't have a table saw, nor the ability to make perfectly cut MDF pieces, thus my curiosity. I'd rather go the "flat-pack" route, but I definitely want the L/R speakers to stand a little taller.
Thanks for your write-up... very concise, but answers all the important questions about the build/materials... and the speakers are beauties!
