Thank you all for your advice! After thinking it over a bit more I decided against crossovers under the speakers; now I am planing to mount them on the back-wall as others have done in the past. This approach will provide more room for better crossover layout. I am considering a 2-1/2" high plywood frame with a 1/4" acrylic plexiglass sheet for the crossover mounting board/see-trough cover (should be an interesting visual "feature"). ;-)
Joe, I sent you a payment for wave guides to build a second pair of Elsinores for my business partner. PM sent to verify. Excited to build another pair. He has no idea what's in store for him. He's heard mine, but it's never the same thing to pop in what you like to listen too, in your own listening room! Gonna be awesome!
Sounds exactly what others and my self have done! With my X over layout there was zero cross talk between my inductors. If I has the chance to build them again, I would have gone all out on the cap's joe mentions are important, and dug a little harder finding the huge choke (I had to use 2). Joes recent post for parts would have helped greatly!
That is right, AudioFanMan, "Only Fools Rush In", as a great man once said! ;-)
I know the subject of the speaker grills is a contested one, but I do like to keep dust out of the drivers and tweeters, so what is the judgement on the best way to accomplish this without too much of a diffraction hit? I saw these 6x6mm Square Carbon Fiber Rods that might work well for a lightweight and strong grill frame ( 6mm x 6mm x 1000mm -PULTRUDED - Square Carbon Fiber Rod - SOLID Square Rod | eBay), just need to find good plugs or magnets to go along with them. Did anyone else build some small profile large speaker grills that work well?

Yes, leave there for background music, playing music while having dinner parties and so on... then when serious listening comes around, pop'm off.
You two Scott's remind me of something I deal with in my business.
"you cannot learn anything because you already know everything." I coined this phrase, and everyday it's proven.
There's a guy who's my "competitor". The dealership he was TRYING to do business with, not only kept asking me to fix what this idiot had screwed up, told me he made a customer CRY, when she got her car back from him!
The only people you've convinced you're right are all the other half witted, "professionals"! Meanwhile, your customers are CRYING! If you even made it to that level. Which we all know with an IQ under 50, you didn't! Which is a relief to all your potential customers!
Joe has made countless people cry out in ecstasy from his creation. He's made you cry out in envy! One of the 7 deadly sins! Oh wait, you check them off like you thought they were virtues... Greed, wrath and pride, even lust. You lust after his recognition, and try to despoil it. And those of us with half a brain see right through you! 5 out of 7 "deadly sins"...nice!
Hi Scott, you make some good points. The Hamlets are not far off and it is basically the design details of the crossover that needs to be determined, we are oh so close.
Yes, the Waveguides are the same.
As I just said to Scott, we are very close. Indeed now to get if finished and get some orders from Waveguides there will be very helpful. It now means added impetus for me to finish the Hamlets.
Please note: The Hamlet's Mk6 will be based on the SB17MFC35-08 driver. This is the driver that is currently available and so that is what the design has to use. Is this a problem for anyone?
Cheers, Joe
I spoke to my own Scan-Speak supplier and because of the COVID winter peak they shut down, as far as I was able to ascertain, for the month of Jamuary. The situation is improving there and hopefully with the uptake of vaccines, things will continue to get better. I am hoping that I might go to Europe in October/November, but that is entirely down to COVID.
er can be replaced by SBA line up like RDC series
As I have mentioned before, the Scan-Speak D2608/913000 has near-unique properties. Even if they cost 3-4 times as much, I would still recommend them. My off-sider in Auckland, Brian Gurr, rebuilds electrostatic speakers and also has a pair of Elsinores. When I say 'rebuild' he does that with mylar membranes 1/3rd the thick that manufacturers do (they cannot because they need robust construction so that they can be shipped around the world). Brian says the tweeter implementation in the Elsinores, which is designed for extremely low distortion, is up there with top electrostatics. Besides, with the added cost of Waveguides they are not cheap, but for what they do, they are worth every dollar.
But yes, I now must get the Hamlets Mk6 going. As for tweeter supply, I am sure it will improve.
Cheers, Joe
PS: CNN just showed a graphic of cases in Denmark, and it has halved since mid-December. So hopefully by now, Scan-Speak is open and able to ship the tweeters, maybe for the first time in a number of months.
I don't have an exact number. Based on the number of waveguides being sold, I know it is well above one hundred and probably 150 pairs or more. It could be near 200.
Edit: It must definitely be 200 since there are a number of Elsninores that did not get updated with the modern waveguide we are using now. My brother-in-law is one of them (must whisper into his ear), so I think 200 pairs can't be too far off and maybe a tad more. There are those that could have made their own waveguides (the design is published) and hence have gone completely under the radar. I have seen pics of some of them.

That is so awesome. I enjoy mine so much, I was just thinking if more people knew what these sound like, a lot more people would build them, and it's a shame more people don't because they have no idea about them. I can only imagine what they would sound like with really hi-end equipment, my stuff is pretty middle of the road, but they still sound incredible. I just thought of this, it's almost like hearing them for the first time each time I listen to them, because I am still amazed how fantastic each time I listen.
This is inside my head every time I listen, "man I cannot believe how good these sound. Good lord theses sound good. I am so happy. God these sound good. OH MY GOD. This is awesome. I can't believe it"
I have a pretty decent UHD player and I like to watch concert DVDs/Blurays if they are good recordings, and every time I think, "no way this concert sounded this good if I was there in person."
On a side note, I have a large CD collection but my last decent cd player stopped working and a friend of mine mentioned audio streaming, and I saw something about music servers, if anyone has any suggestions on that, I have been converting all my new cd purchases to FLAC, since I have a real nice Alpine in my truck that plays them. Not to hi-jack the thread, just post links if you have any, and I'll research it.

Looks like I was lucky to receive one of the last waveguides... I’m in the US and it looks like there has been some chatter here in port sizing (for whatever reason we hate metric here). Anyone have a workable solution?
I’ve checked out McMaster Carr and they sell poly carb tube in either 3 1/4” or 3 3/4”; eBay has this tube that’s has a 90mm OD. Doesn’t seem like PE has the correct diameter tubes at the moment.
I’ve been estimating box volume at 15L and the tuning at 20Hz - wondering if this is way off base or not? I’m curious to hear solutions that other’s have figured out.

I'm about to build another pair myself, and I'd like to know this also, since I don't remember exactly what I did. I bought flared ports from Parts Express and adjusted the length with a port calculator, but if someone else can make it easier that would be awesome. I can look at my purchase history if you need to know what ports I used.
Ignore this. I looked last night but did not see the "PC section" with a subheading "music servers" I see it now!
Looks like the estimates should have been closer to 100-120L and somewhere between 30-40Hz. It’s looking like this 3” port from PE could just be cut to the appropriate size.
I can calculate the box volume more accurately given the construction drawings, but would be useful to know the ideal frequency for the port tuning.

IIRC the volume was about 81L before bracing. In the end it seems 75L is where most people end up after bracing.
Pretty sure 32-33Hz was the goal, but on Joe's page
Elsinore Data Gathering his example was at 35Hz.
I believe he has mentioned somewhere even 38Hz was kinda ok...
But, my memory sometimes makes stuff up lol...
