Ken is printing waveguides for the tweeters, and I just bought 0.34 cubic foot flatpacks from Cinergy since it is too cold to spend too much time out in the garage. I can glue them up indoors, and then maybe cut one driver hole at a time as weather permits.
I will flush mount the tweeter, but surface mount the woofer.
I have noticed on many smaller drivers provided Q is > 0.5 and they are relatively low compliance you can expect excellent cone control below tuning - at the cost of a somewhat large (relatively speaking) enclosure.
Anyways, will be my last budget banger for awhile, need to focus on some of the nicer designs I have in the queue.
I might machine the baffles for these this coming Monday. I am using a flat pack from Cinergy.
Speaking of, PE could learn how to pack flatpacks from Erich. He actually uses expanding foam in the corners to keep the flatpack stack from sliding around. At first it pissed me off trying to get the product out of the box, but when I finally saw why I was genuinely impressed.
I have my SLA printer set up and running if you want some REALY nice looking prints let me know I can bring them to InDIYana. I would like to get the screw height corrected if possible.
I lied, but I do plan on gluing these up tomorrow and having a big sawdust day on Sunday as I machine two pair of baffles. I was really hoping to have these farther along by now.
This is as detailed as I plan on getting with the CAD work. If someone wanted to build these, and who would, they use 1/2” material. I would likely point people in Erich’s direction if they actually wanted to build these.
Simple construction, single shelf brace mounted at the midway point. Note, I front mount the port on these strictly because there is too much baffle left over after mounting drivers, due to the tall and skinny nature of the cabinet. If I had it to do over again, I would have ordered a different flatpack. I would have ordered these, instead:
Anyways. I like a populated baffle and my external dimensions to be more or less close to the golden ratio. The ancients knew what they were doing when it comes to aesthetics.
Slight change of plans. The waveguide has some mounting concerns (Ill message you, Ken) but in the meantime I will be using the venerable BC25TG15 in its place. Should work pretty well, still fits the budget.
