Chris - you mentioned being able to make both speakers from a single sheet or offcuts. I've approximated the area for the all the pieces required and it looks like a 2' x 4' sheet would be more than enough. Does that sound correct?

Thanks,

Rick

yup, these are not huge boxes - I'm so often cutting for multiple pairs of kits for the smaller designs or using offcuts that I can't remember the breakout for a single pair

FF85WK uFonken vs. Bass Reflex
When we were making the 1st batch of uFonken, i seem to recall Chris said he could get 5 pair out of a 5x5 sheet of 12mm BB.

I went ahead and did the drawing. With no trim allowance, & a 5mm kerf you can get 1 pair out of a 251mm sreip 1314mm long. So with care you should be able to get 2 pair out of a 24" x 48" panel of 12mm.

So you might be able to get 6 pair out of a 5x5 sheet with careful optimization. Close enuff that less trim allowance, and a smaller kerf might make the difference.

when cutting this quantity of parts on the big beam saw, we need to allow 5mm kerf for the main blade, and 10mm trim cuts, but I'm sure there was still a little left over from the 5 pair

uFonken gets to about 70Hz F10, the new slighly larger uFonkenPlus goes 5 Hz lower.

Yes. The existing design is for the original FF85k.
