6L6 and Bob,
You guys are neck and neck. Who will be the first to FIRST SOUND? The race is on.... 🙂

😀😀😀 "What He Said" - Simply amazing sound from a tiny 3" driver. I haven't even put anything in the horn yet and just plain got a great big smile as I shook my head in surprise. Any doubts I may have had about the wisdom of investing in some top notch drivers for these have been completely erased.
As in the picture, these are up against my favorite speakers - The Sunflowers - and though they fall short in comparison in the definition and sparkle at first listening, there is no doubt the Cornus could and will provide exceptionally good sound to all who attempt the build.
I am now at about $40 in this project and the Sunflowers ~ $450. It's a no-brainier for anyone wanting great sound at an unbelievable bargain.
I'll be stuffing and tweaking for the rest of the day. Thanks Xrk and Cal for the support and enthusiasm, 6L6 for pointing me to the thread in the first place.
IMO, the Cornus have a very high potential for serious development and a high level of enjoyment for all.😎

I'm playing this album now and am just floored. The cello's full range from top to bottom is just about perfect. The instruments are placed in the stage accurately and all the resonances of all the strings are beautiful. The hollowness of the instruments can even be heard
SIMPLY AMAZING !!!

Congratulations!! They look wonderful. I've seen a vision of what I'm in store for.
By the way, I brought up this design with my audio engineering teacher and he pointed out a problem with the design that could possibly be fixed with little trouble. He noted that the shallowness of the speaker is going to lead to a cancellation around 2k from the bounce off the rear wall. His hunch appears to be backed up by a couple of passages in the 6 moons review:

The solution, if there is one, might be to simply place a sound-absorbent deflector behind the driver. I might experiment with this."When the Cornu CS was on display at the Triode Festival 2004, it was equipped with a plastic front horn. Daniel was not secretive at all to reveal that there is a frequency response dip below 2000Hz and that the front horn was meant to remedy the problem acoustically without electronic filtering....
...Said dip was clearly visible in all the measurements I made. Judging from the window of this depression, it could be explained by diffractions and internal cabinet radiation."
Wait till you hang it on the wall! Even more amazing. I am glad this wrked out for you. So it looks like little Vifa works in a 24 inch x 3.5 in thick cabinet beautifully.
Like I said earlier, the cornu's reignited my interest in listening to music again. You hear cd's in a whole new way you never thought possible.

The only other speaker box that has ignited so much fun for me with speakers is the Altec 825 known of course for the A7 VOTT. Both of them lend themselves to a wide variety of drivers. This one is a little more, how you say, portable?

This explains the nosecone placed behind driver in patent drawing. I made my left and right cornus slightly different: I have a sandwich of foam and plumbers' putty in the back of one. Maybe it will show up in a measurement?

I'm really looking forward to the wall mounting. The Vifas are super and I have used at least one in all the projects I have done over the years.
In addition to the pad suggestion, I've been thinking about a way to insure all the throat dimensions are accurately at spec. Maybe a brace of some kind. I know mine are not totally uniform.
Just waiting for 6L6. Maybe he got caught up in the listening part. I know I did. I think I diappeared for an hour or so just trying to wipe the **** eating grin off my face.
Depending on your tastes, you may find it a little boomy when it goes on the wall but you said you have a good supply of pillow stuffing to add if needed?
Almost a bushel left. PE just lost a stuffing customer. 🙂
As the mind wanders, can you imagine a 5.1 or 7.1 theater system with these. Might not even need the "1" 🙂

He, he, you are not gonna stop thinking about them, I can tell. 🙂
I never thought about HT but this is good from standpoint of not taking any floor space in your HT room. The micro 14 inchers may be sufficient for rear channels, the mini or full size for mains, center channel just standard sealed skinny box with single Vifa to fit under tv screen. Very cost effective.

HT was the first thing I thought when I saw this thread. Think about how speakers are mounted on the walls in movie theaters.
For those who have long been bitten by the bug (specially bass reflex), as soon as I got the first driver in place I did that
"thump the cone - OOO! that's gonna be good" thing. 😀
I did not get what I was looking for this morning - but boy was I wrong. 😉 These enclosures are really different.

Is thumping the cone like kicking the tires?
So it did not respond well to the thump test? But sounds good regardless?
