No problem

Drill a center hole "straight" through a board so the pin on router circle jig fits in snuggly.
Cut the waveguide opening first and clean out then flip and cut the tweeter
opening.

I made some lines with a square to line up the mounting holes.

The tweeter holes in subfront will need to be enlarged(shallow) to accept the back of screws.

Havent done this yet but thinking I should make the tweeter recess pocket in subfront a little deeper and use a foam gasket to seal behind mounting plate

Hope this makes sense
Joel

Finally finished crossovers and inserted inside cabinets. I used 22mm MDF cut to size and carved with router to insert passives. Once inside they covered by damping material over the top.

Now it is time for waveguides/horns, I find ready made ones which should serve the purpose in here:WG-300 - Monacor special horn front attachment - wave guide - Europe Audio they are intended for monacor, but size is the same: Any suggestions?

Wile it looks similar, the size of the Monacor waveguide is quite a big different from the recommended waveguide for the elsinores. Based upon the diagram they provide, the Monacor is quite a bit larger. Compare against:

Regarding your coil placements, you might want to reference:

My question is have you worked out the port length and diameter for the Hamlets yet ? and will the hamlets use the same waveguide arrangement with the tweeter that the Elsinores use ?

Many Thanks
Sorry for the delayed reply.

You would be best just to do the Hamlets without the Waveguides.

To do a Mk5 type Hamlet speaker I would need the boxes here with drivers mounted and Waveguide too.

Then there would be several days of work... and the result cannot be guaranteed (it would probably end up OK). And I would like to think the result would be better too. But it comes down to actually doing it. But there are no short-cuts.

I don't have Hamlet port dimensions here. I think Rob323 should have it. Or does somebody else reading this have it. I never did build the Hamlets myself.

You and Ian must be getting close to getting Mk5's ready?

Cheers, Joe R.

Been WAY too long since I have gotten time to advance this project. Unfortunately, life has a way of creeping up on you like that.

Anyway, it was 76F and partly cloudy this morning in Florida. A nice break from the heat and a perfect time to cut and straighten lumber!

Used a circular saw jig for the rough cuts and a set of guides for the router to fashion the end product. Man, I had no idea a router was quite this versatile! In three passes per board with a flush bit, I had perfect boards and each matched the next one exactly. This is enough for the front sub-panels, internal braces and half the back panel for what will be my "internal" box.

Next up is the side panels and then time to start assembling the pieces.

Will do.

This is a nice diversion into real woodworking for me. A heck of a lot different than the home improvement variety I typically get (have?) to do.

As for waveguides. I have bought mine from Joel. The quality of the guides Joel is having made is impressive to say the least. Highly recommended.

My wave guides came from Joel too - very nice!

Too busy at work to finish it in the next 10 days, but my Elsinores need only about 10 more hours to complete. Can't wait!
