North America wave guide GB
Joe,
Thanks for the wave guide information and pictures and also the future dimensions and drawings.
If everybody that responded earlier is still with us, including BHD and mantraxl, we have 7 in our group, assuming the final cost is acceptable to everybody. We shall appreciate it if you and Steve would let us know how to proceed the negotiations.
Thanks,
Francois

My first post so be gentle with me.
First batch of waveguides will be sent to Joe next Monday.
Long time follower of this thread.
Elsinores has been my first effort in the DIY audio world and I am blown away with the results.
A couple of photos of my pair attached (I hope)

Hello
Just wondering if it matters if the drivers are installed, rotated by 90 degrees?
So the flats of the speaker sides are vertical with the side of the cabinet instead of horizontal.
Just for a different look thats all.
Well done greenpea looks great,the picture reminds me i still goto make the grille frame.Thanks for the waveguides.
Currently trying to set out the coils on a4 paper for best orientation any suggestion appreciated.
I was looking at humbles website and he packs the stuff really close together, couldn't find one with five coils though.I did see his write up on coil placement but the five on one board got me.
Cheers Paul

Hi Paul,
Changing the driver orientation should make no difference, as long as you manage your wire connections.
My layout is most like your Pic 1.
Apparently lab measurements indicate that any crosstalk is very low after about 50 mm between coils I usually go or the greatest separation allowed by the dimensions of the mounting area (or box). Another rule of thumb says that when you look straight through the whole of a coil you should not see another coil behind it, especially not one with the same coil orientation. Pic 1 looks the best in this regard also.
My 2 cents. Good luck.
Francois
Good news about the waveguides and congrats with your superb looking Elsinores. They speak volumes about your craftsmanship.
As you know from earlier posts we have 7 people in the US that expressed interest in group buying 7 pairs of waveguides, pending the final cost. Would you and/or Joe prefer to proceed by private mail in our discussions?
Then please send PM to me.
Thanks,
Francois

Don G contacted me and might join in the waveguide GB if he could find someone to build the crossover for him at reasonable cost. Anyone?
Joe and Steve, we are now looking at a GB of 7 or 8 from North America.

Hello BHD
I do not recall if I entered my name as part of you GB but count me in if not. I know a Machinist who makes the molds for such pressings for the automotive industry and he may be willing to mill from aluminum, the mold shape you will need for a plastic pressing/mold! Should I contact him in this regard? We/ Group will have to buy a slab of aluminum and he can mill per our spec's. He is also willing to Mill other things like baffle plates or anything imaginable really! Get back to me if this avenue is of interest!

Hi Guys,
Would anyone in the states be willing to build the MK-5 crossover for me?
Preferably someone who has yet to build theirs.
I would send the funds to cover the cost of the parts, labor, and shipping.
My expertise is cabinet building, and the knowledge of knowing that if I screw up the crossover, just a little, I've ruined a perfectly good loudspeaker. Anyone interested?

Following a cross over wiring diagram isn't very difficult, worse case someone should be able to post a picture of an assembled cross over.
Can't be much more complex/difficult than soldering a couple of wires together. Even a inexpensive radio shack iron should do.
Just practice on a few wires and you should "get the hang of it".
If you are really worried about mucking it up, you could use jumper wires to assemble it and try it with your speakers. Once your satisfied that it works you can then solder it together.
If you can master the skills needed to assemble a set of cabinets a cross over really is simple (in my opinion).
I've been watching this thread since it first started, this new version has piqued my interest.
I've been looking for speakers to run with a set of Dynaco MK3s.
Has anyone recently priced out the total parts prices? (drivers and cross overs) I understand that the waveguide is TBD.

Hello Joe, in regards to the wave guide and respectful of your friend & assoc. Steve and his hard work, I like the way the problem to solve the flare of the tweeter's FLANGE has been approached. (Post #698 illustration) However may I suggest another maybe simpler approach? Remove the flange and model it's shape as part of the Wave Guide substrate (MDF) and mount the dome and motor section direct to the guide eliminating the flange but incorporating the flare at the mouth (inlet) into the MDF as part of the initial shape. In this way you may have better control of the thickness and proximity to the dome you can be. Your views?

I think I know what you mean- mount the driver sans flatplate directly to the back of the MDF panel-? We did contemplate this method but Joe was reluctant to have the driver mounted to the WG, as he would rather have the driver mounted directly to the front panel structure of the Elisnores to ensure it is very "solid", and then just have the WG mounted seperately "in-front", forming no structural purpose. Joe might want to confirm the theory/reasoning.
Below is a photo of the prototype WG in my pair- I had the luxury of fitting the WG panel very neatly into the "cavity" (where the felt used to be), but it took a bit of fiddling around trimming the edges to match "my" cavity exactly. It all depends on how accuratley (centered) your tweeter is mounted in the cavity, and the size of the cavity itself. That it is why we suggest having a small gap around the perimeter of the WG and to your cavity, trimmed to have it even, to make up for the differences in tolerance between each and every Elsinore fabrication

Hi Guys
Steve has taken my rough drawings and come up with more detailed drawings, so I have decided to post them here:
OVERALL:
CLOSEUP:
For those inclined to make their own, go for it. But for the rest of us, we can appreciate Steve's efforts and the take advantage of his efforts.
Cheers, Joe

Hi Guys
Received the first batch of waveguides from Steve "greenpea" today.
I've got to say that he has done a beautiful job and after talking today with him on the phone, may I simply say that the hours he spends making these... well, he is not making much for the time he puts in.
If these could be made with a CNC machine and cut down the time... ? But these are hand-made.
The first pair was posted to "spoonted" this arvo (that's Oz for afternoon - mustn't forget the international audience).
The MDF is completely sealed from effects to moisture. The Front of the Waveguide is grey undercoat and very smooth. The Rear is also an undercoated, but this is a kinda rusty yellow.
Cheers, Joe
