Dave,
I really haven't looked into the printing material yet. All I know is what I've seen at a local UPS store that prints small objects - not big enough for what I want. (I'm thinking of a large bookshelf design maybe 14" wide by 16" tall, with the driver up maybe 2/3 of the vertical dimension). They have 3 materials at the store that I've seen: a softer, more porous material; a medium-density material; and then a rigid resin product, which is what I think would be best for a speaker baffle. I need something that will hold a screw, if possible. If not, it will need to be drilled out for an anchor. I'd also like to integrate the base of the baffle with the face during the printing process, with an integrated cradle at the back of the base, which would come up to support the back of the driver. I'm thinking that I would need some sort of rubberized material (like Steve puts between his DM945 and the Companion Cabinet to make his Monoliths) lining the cradle to cut out vibrations between the driver and the cradle. This is all just rolling around in my mind at this point - I haven't set pencil to drafting paper yet. And, as I said, I need to make a couple of different-sized mockups out of wood before settling on a final design, as I think the 3D printing process is still a little spendy, and I'd like to get it right the first time.
As for using the AMT in conjunction with the FRX2, I'm not planning on doing that, as I'm trying to keep my system as simple as possible. I know that overtones can add to the realism of music, but at my age, I'm not sure how much (if any) tones above the 25KHz that the FRX2 puts out are making it through to me. Sad, I know. I wish that I had gotten into this hobby years ago, but I'm enjoying it now, so what the hell.
Anyway, I think that if enough of us express an interest in the FRX2, maybe Steve will be motivated to make another batch. If I'm reading the webpage right, he builds these in blocks of 10. I'm not sure if that means that he waits until he has orders/deposits from 10 buyers before he starts a batch, or...? I guess I wouldn't blame him if that's the case. I need to sell a couple of sets of speakers and an amp or two before I get serious about this project, but when I do, I'll call Steve and get some answers to my questions. I'll post what I find out for others who might be interested.
