Hi Danny, appears we are waiting on flatpack pricing. It occurred to me that it might be cool to get a price (for the baffle only) from the aluminati guys, they do incredible work from what I have seen and I wouldn't think a small baffle would be too expensive. Of course they would have to have a means to connect it to the rest of the speaker, this could likely be accomplished with threads for 4 bolts at the bottom of the baffle, for the wings they may be able to cut an angled groove. An anodized baffle could look cool.
Just a thought.
Best,
Ed
