[QUOTE="Don J Davis, post: 139045, member: 248"] Re: New DIY Mid High Sorry for the delayed response, been out of town doing a large Easter event. Mark, ask away, I’m learning lots as we go too. There is no need to have Part D if you don’t want it. Peter confirmed that before the drawings where released. I thought it might make the assembly easier and add a flat spot to mount the Speakon connectors in. Yes, on the angles, you can use whatever you want, I just drew what the cad system suggested. Yes, the ports need to be all the way to the edges per Peter. The adjacency to the horn wall adds length to the port depth. Also, Peter uses those as access to tighten some of the bolts on the 12s. I plan to use blind inserts in that triangular piece of wood you spotted below the baffle. I didn’t detail it since I’m not sure how many people will build it that way. I do have an ulterior motive for the removable baffle too. I hope to be able to change out horns from the 90x50 to the 60x40 depending on the deployment. This would be done in conjunction with Peter’s design of the splayable version of the box. That way with a horn change the box can be used stand a lone or two aside. I haven’t gone much past the idea stage with this so far. I haven’t chosen a gasket material yet. Something reusable and not to thick attached to bottom of the baffle. Some small pieces of wood will need to be installed like a ledge on the sides for it seal to as well. I’m a little concerned that the top edge of the HF950 may be very close to the front edge of the cabinet making it difficult to recess a grill if used. Per the plans there is 15mm offset but the HF950 flange is 13mm thick. [/QUOTE]
