Bob just finished his build on the other thread! Check it out.
Foam Core Board Speaker Enclosures?

Congratulations Bob!

6L6 just finished his Cornu build. Congratulations 6L6!

Ok, that makes the list of folks with successful cornus:

Cal Weldon
Pano
Bcmbob
6L6

Am I missing anyone?

Cal Weldon · 21st December 2012, 08:30 PM

I thought Pano still has issues.

His speakers I mean, I know about the other ones.

Pano · 21st December 2012, 08:31 PM

Uh, thanks Cal.

I dunno if my Cornu has issues, or it's just the stuffing. Anyhow, I'd like to get the FR smoother.

To answer an earlier question:
When scaled to 20", the Planet10 PDF gives a mouth size of about 3.75". That's measured from parallel side to side on the section after the first corner. I.E. the first significant straight walls.

Were you answering my question? I think my question was actually, what was the width of the throat section next to the driver?

A true Canadian B.S. session! Do you remember who won, the home team or the visitor?

Not sure what part that is. The opening into the horns?

xrk971 · 21st December 2012, 09:32 PM

Yes, the gap of the horn inlet from the driver chamber. You and Cal look like you are in the jungles of Zimbabwe about to test out acoustic shock therapy for gorillas in the mist.

Yes, where the BS stands for Be Serious.

Pretty close, it's the wilds of Canada.

Actually that's a rocket powered speaker you see us attempting to hold down. Eventually we just had to let go. Serious thrust from that puppy.

I don't know if mine are successful, but they sounds quite good
