Well, you know me. There's no challenge in doing it the easy way is there!

Can anyone volunteer a couple of pictures of their x-overs? Not sure I can come to grips with 10 speaker cables a side!
There is only 6 cables per side (3 pairs) and to simplify things and to prevent me from doing something stupid (which happens often) like accidentally plugging the tweeter into the bass output from the crossover, I am using 8 pole Speakon plugs. I will take a pic tonight of what I have done so far with regards to the cabling to give you an idea.

Between the x-over and speaker plus 2 pair to go between the x-over and amp(s)! Purely based on my interpretation of the wiring diagrams, and I have been known to be wrong - very wrong! Those plugs sound interesting, thanks Rob.

Anyway thanks for the links rabbitz!

My apologies, I forgot about those.
I do not have mine bi-wired/ bi-amped at the moment, just single cables from the amp to the crossover box and jumpers to bridge the terminals at the crossover box together.

meataxe, pics of the Speakon plug/ crossover box setup as promised.
Click the image to open in full size.

It sure simplifies the back of the cabinet, and no speaker cables hanging down in front of the port.

The drivers ended up as flush as you can get them (yes they are dusty).

Extra chamfer around tweeter recess.

Thanks for the link. I will be interested in getting some MOX resistors and possible Jantzen caps.

Have you actually bought items from them before? The Website has no address, no telephone number, no "about us", basically nothing except part and price lists and possibly a payment system, ... I would not know who I would be paying to.

Yes, I've bought from Steve previously and he is the authorised Jantzen reseller in Australia (also listed on the Jantzen site).

Good service, good product, good value.

As with a large portion of resellers and myself included when I was running RZaudio, there was no phone or address included on the website as the business was web based only and mail order.

Hello,

I'm building too the Elsinore speaker, now I'm cutting the wood.

And I did a mistake in the hole for the tweeter, it isn't a circle

I didn't used the blade suitable for doing circular cuts and it was hard to get the blade in the direction I wanted. The hole diameter is 80-82mm. Is it still ok? os is going to effect the sound? in the worst I could always take another panel and do it again sigh

But the second hole I made is good

If you can flush mount them, then I won't object - the slight change in relative to Tweeter offset is such that they will focus at slightly greater than 1.6M I did the published the Step Response - so it is actually still with +/- 2.5mm acceptable range. There is also a very slight diffraction effect difference, but is so small as to be inconsequential.
Yes I could flush mount the other drivers, but sorry for my ingorance I didn't understand a lot. I'm, going to listen to them at 2,5-3m distance, so it's better to flushmound the mid and the bass driver? if it isn't worth I don't do it

Thank you very much

Peter, after going to the effort to flush mount the drivers, I wouldn't bother to do it again. It is not fun due to the shape of the drivers.

Also, are you building the Mark 2 versions or the Mark 3? Going from your picture, I say its the Mark 3, if so, don't forget that the tweeter should be recessed into that panel. Do you have a router?

Yes I'm building the MARK3.

Yes I have a router, with this tool is easier to flush mount. But it's always more work to do, and if it isn't worth doing it it's better to not do it....

Now I was thinking to glue some pieces of MDF to the bad hole to make it more a circle, is it a good idea?

I wouldn't be too worried about the hole for the tweeter but best to hear that from Joe himself.
