Hello Guys,

I ordered Joel's waveguids ages ago but never got around to actually building the speakers. I've gone through the build thread with renewed interest and, with respect to the waveguide, I conclude that I should mount the tweeters to the waveguides before mounting the waveguides to the cabinets. There is a photo by JkdJake where a gasket is shown to seal the tweeter faceplate to the back of the waveguide. I believe that is good practice in any case.
Apparently there is also is a small gap, between the tweeter and waveguide, around the dome of the tweeter. If I understand correctly, this was not an audio design objective, but an intentional tolerance to make sure that the tweeter will always fit securely. There has been some debate whether this gap should be sealed or not.

I wonder if there is consensus now on this issue?

I can have more made..The machinist has raised his price so I would need $180 per pair.. I have to get min 5 pairs at a time and would need money in advance as I cant justify holding stock because I'm adding very little for time and fuel... If 5 people are interested, no problem...

ABO, as for the gap you should just try it both ways and then you will know which one is for you.. Each way is different good.. One way is gap without putty and the other is tight with putty.. I'm guessing that some energy at the large diameter of the dome is getting trapped in the gap so there is a loss of richness and detail but its smoother and more laid back than the tight fit... Take your pick but I chose no gap..

I built my own wave guides out of mdf,that I like the sound of a little better than the metal. I have a pair of Joel's aluminum wave guides I am not using, I will sell for $150 US plus shipping. I don't know how much international shipping would be. Not trying to get in your business Joel but I would like to see someone get some use out of them.

Out of pure curiosity. Why did you prefer the sound of the MDF waveguides? What difference did you notice? I built my Elsinore's in 2011 using Joe's MDF waveguides but if I was building them now I would probably use Joel's round alloy ones (if obtainable) as I think they are aesthetically more pleasing but I've often wondered if there would be an audible and or measurable difference between them and Joe's MDF ones. I have observed that a machined piece of alloy rings somewhat when struck whereas a piece of MDF is quite dead. Food for thought.

I have an extra set of high quality coils and capacitors from Erse Audio to sell. These are the same parts I used to build the filters of my Elsinores. This is an almost complete kit, only the resistors and C1 capacitors are not included. All parts are new and never been soldered. I paid over $300 for these parts and I'm selling them $200. pm me for details if you are interested

I found that the mdf wave guides were not quite as bright or edgy as the aluminum guides. I was also able to control the gap better with the mdf. In my system the gap made the presentation much more 3d with nuances that I didn't hear with the gap closed. Also, I could listen to the speakers for hours without any fatigue. At first listen the closed gap sound jumps out at you more and is more "impressive".

That's very interesting as I find mine a very easy unfatiguing listen. Others have agreed (love showing them off). The gap between the tweeter and the waveguide is as per the original design dictated by mounting the tweeter facia flush with 25mm baffle and the MDF waveguide flush with the two 18mm front baffle pieces which does introduce a small gap. A collegue of mine has access to a 3D printer and if possible I would love to print a waveguide and compare.However I will have to model it first in a CAD program (SolidWorks). Learning that will be the hard part.
