Curiously enough, this sounds like the mechanical version of the Magneplanar speaker. The Magneplanar had similar timbres in it's reproduction capabilities and it was always considered to be a symphonic reproducer as opposed to be a rock reproduction system. Inherent in it's reproduction capabilities, it was noted for its pristine reproduction of the higher frequencies, while it was always lacking in producing substantial lower frequencies.

It's going to be Real Interesting to hear them.  A real roll of the dice.

Well then Luke, get cranking on these bad boyz...I'm very interested in your opinion of these speakers. I like what Bob has to say:
"So you have been warned. If you are into polite genre and moderate levels, my speakers are for you. If you are into heavy, loud music, you need to look elsewhere."

Just curious, have you had a frequency hearing test performed on yourself and if so what were the upper & lower limits?

They are getting there.  Should be ready when the veneer arrives late Friday.
My hearing.  I estimate in the 2Khz to 12Khz. range. Power Tools n R&R don't cha know.

Just wondering, because about 40 years ago my upper limit was 17,500 to 18,000 Hz. After 40 years of exposure to cars, motorcycles, fuel dragsters, power tools, guns, loud music and small, shrill barking dogs...it's down to around 12,000 to 13,000 Hz. I think this a great reason why hearing protection is mandatory if you still want to enjoy music and quiet conversations later on in your life.
 
It's in the bag.  We will see if I got incredibly lucky and not have the burl shatter around the edges of the holes.
The holes should have been plugged/supported.  The sound when the burl was sucked down was sickening. [eek]

Do the drivers have a bezel or surround that would hide any possible imperfections in the immediate area of the holes?

They do. 
It's going to work out
 
This is an interesting thread, as I have thought about building speakers.

So, thank you for sharing.

Regards John
 
even tho I have read everything in this thread, i got really lost there for a while.  I knew nothing about what was being talked about.  I did begin to realize that there are hundreds of ways to build/manufacture speakers and sound systems.  I told a while back about the cabinet my dad had built to hold a "Victrola" hand cranker with the cow horn megaphone to put out sound.  Thru the years, that cabinet has received many changes in the sound methods used and the qualities of the sound.  Once Mom. my brother and I moved back together, we added radio to the cabinet along with better quality phonograph.  Each time we upgraded, Mom had a different person (Xpurt) work on it.  Sometimes for better, sometimes, not so much.  Now, even tho i understand nothing about what has been said about sound systems, i do understand that with each "upgrade",  a different audio Xpurt might have been aiming for a different result.  As i remember some of our complaints thru those years, i have a little better understanding of why many results seemed to have gone in different directions.

Luke, you continue to hit very educational and enlightening directions to your posts.  i can not tell you enough how much i enjoy learning from your subjective contributions.  You just seem to suck in so much wisdom from all of the responders who are curious enough to enter into your lair.

Oh, BTW: Even tho i have not tried the vac bag method for veneering, i have learned one more thing I had not read about it the past.  That little number about supporting the edges of the veneer around open holes, as another has mentioned, I,also, would not have thought about that. That was a small note, but will be well cataloged in my dim brain.

Yup.  Those were the days.
This one is in our dining room.  Haven't cranked it up in 20 years.  The needle looks like something you would use to sew leather.

Not a good day in the woodshed.

Where to begin?
I really should use a top caul. One would think after 3-4 veneer projects I would learn that the excess material on the edges will bend down and crack.  This is especially troublesome with burl. 

I routed the edges and it’s not too awful.  There are a couple of checks that need to be filled with repair wax.

It get worse.
There’s always a lot of drama for me during veneer glue up.  Mixing the darn powder so there aren’t any lumps.  Rolling on the right amount of glue.  I was thin on the last couple projects….. So I went too heavy on this one.  I ended up with quite a few squeeze outs.  It was tough to get them off and Sure Enough, yes, I sanded through in ca couple spots.  I have a patch drying on one area.  The other won’t be noticeable because of the patter in the burl.

It gets worse.

Before gluing I taped up the book match for the pair.  Only it wasn’t a book match, it was the identical orientation.  No problem I had two panels for the top.  Taped them up in the correct orientation so the left speaker and the right speaker are book matched.  Then I proceeded to trim material from the bottom and not the top.  No problem it’s another seam.  Checked everything three times went to glue up (above).  When I pulled them out I noticed that the seam between the two panels was very visible.  Why?  Because the pattern was flipped.  On Both Speakers.
Note pattern and seam three inches below the speaker hole.

That seam should be near invisible

Some of these mistakes/mishaps might be circumvented by a better method of annotation. Last week I watched a lot of Japanese cabinetmakers (on YouTube, not IRL, sadly) and one of them made extensive use of chalk in different colors. He would mark pieces of board etcetera after deciding where each had to go.

That might also work with veneer, if you used numbers and a mark for top/bottom/R/L and whatnot. Or the classic woodworking triangle…

(I guess that chalk won’t impede glue ups and is removed easily.)
 
Personally I still think it looks great and if it was my project I would be quite please with it.  Will you try it again on the reverse side?
 
Last night I put a coat of Deft on the burl to see how the mistakes pop and determine if a glaze could hide them.  Not a chance.
Then I dry fit the sides and realized that that burl is butt ugly.

Off to the hardwood store to see what they have that I can re-saw thin.

If Ikea sold Leopards?

Or fuzzy like Billy Gibbons guitar.
The camphor burl actually looks worse in person.  It didn't even look good against the white maple.  What was I thinking???
I just now, picked up a nice piece of quilted maple from Austin's Hardwood.  I will re saw it down to a couple mm.  I can book match it and I don't have to bag it. [smile]

Can you get a photo of the re-saw with your third hand please? I'm curious. Not about the third hand, that's a given, but about the re-saw.
