Thot some people might be interetsed in how this project is progressing.
Bernie dropped off the 1st prototype so that Chris could build and provide feedback.
I took the opportunity to do a dry fit and take pictures.
Hopefully i can get them in sequence.

Western Red Cedar is quite plentiful here, and speculation about using it as a speaker building material go back over 10 years.
Bernie recently rekindled that interest, and finding that an Italian hi-end tone arm maker had tested a huge swath of materials for arm wands and ended up choosing cedar really goosed us to get going on it.
Bernie has a set of proto Mar-Kel70mT in cedar -- they are making the rounds, but initial testing was very promising.
The vision for these flat-paks is to provide something very hard to screw up in assembly - being solid some care with finishing will be needed. Alot of pre-assembly will be done here.

Nice! I see biscuits.
Bernie has already decided that the biscuits do not meet his standards (they are too sloppy). There will be experiments with other devices to ensure that there is no thot required alignment

Dovetail joints would look amazing in those boxes, but probably a royal pita. Dowels would be easier.

If it will survive for 20+ years on your roof, I don't think there's too much to worry about.😉

We'll see. They will come with no guarantees.
They will need some care with the finish.. Do not remove from the shrink wrap until you ar egoing to build them.
dave
hmm, clean machining of dovetails in material as soft a red cedar could be very problematic indeed
I think a small box consisting of 13 pieces glued together (some edge glued and 3 layers in the side walls) no matter how careful the grain alignment' is quite different from a shake roof

Yes, shingles/shakes on a roof can crack and still perform.
Interesting to see how they'll hold up.
Great work, btw.
-offering those packs will allow many more people to hear just what a great design these cabs are!

I bet they smell nice too.
But the driver recess isn't round, the EL-70 is round - looks more like a Fostex driver was planned for these boxes ?

joinery solution???
I am certainly not a cabinet-maker or anything like that but offer some food for thought regarding the cabinet joinery dilemma. Would lock-mitered joints be at all feasible for a design such as this?

wow, those polka dot drivers do look good - the gold/bronze finish especially well suited to the cabs.
neither am I a journeyman jointer, but in a few words - I don't think so
stepped dadoes maybe, but keep in mind these are pretty tiny, tapered boxes not subject to a lot of stress, and with quite a bit of glue surface area - I'd imagine that with any wood glue better than library paste the simple butt joints would be quite sufficient
Fonkens always have a Fostex in them...
dave
as Country Joe might have said
"give me an F, dude "
for Fostex
well, OK , he didn't say the last part - that was me
John,
You might be behind Ced, but consider it done.... now we just need to work thru all the testing & detail.
