I know, I get that all the time.
It's a good Idea!
I might have to try my hand at it!
How thick is the Delrin you use for cases?
Plastic is relatively difficult stuff to work with.

I apologize if you were offended by my banana comment. I appreciate fine workmanship of which I am quite incapable.
However I sometimes have built amps in unusual containers and my first thought on seeing your photos was 'how could I build something' with a banana shape. I have been pondering the idea ever since.

They went very well with the same Goldwood 18" 1858 speakers that Roscoe uses in a similar JE Labs open baffle. The crossover is a PLLXO with bi-amping.

Chris, I'm not good enough to build those enclosures. I just use a slab, whatever I can get on eBay cheap, 1/2" to 2". I have a HUGE chunk of 2" right now. I think it's 4' square, for future projects.
Charlie has an awesome Passive line stage machined out of a solid chunk of Delrin, probably 4"-5" thick! We have listened to the identical P&G pots in three different enclosures, the Delrin one, one of Bubinga wood ( by David McGown) and one Guy Riffle made, I forget the material, chocolate maybe? But the one in Delrin was head and shoulders above the other two, which are both EXCELLENT.
My phono stage uses a 1" thick slab on the bottom of a cheap metal enclosure. I KNOW a better enclosure will improve the sound overall.

or something similar.
I'm thinking of getting a 2x4 piece and carving out a banana shape and painting it yellow. Apparently the transducer should be placed asymmetrically which should not be difficult with a banana shape. I presume having the banana vertical will be better than horizontal.
Perhaps this belongs in a separate thread (for the insane).
