Hi Andrew
Long time no speak.
Here are the plans (and ACAD files at bottom) for the Autograph corner horn...

One Harvey "Gizmo" Rosenberg had a pair of the Westminster horns in his room. Albeit a giant huge, not very live room, fyi.
Not impressed.
It was run with a very wide range of tube amps and some solid state amps, iirc.
Imho, the little "horn" on the front doesn't buy you much of anything. The bass loading & output for that particular speaker was spectacularly poor.
Otoh, Martin's loading system does work - having heard his speakers. He gets rather impressive results from rather small and anemic looking drivers that in a sealed box or small ported box would likely not do much. So, if you build a speaker that has a folded horn of some sort that only mimics the Tannoy plan you might perhaps be on safe ground.
Just thinking out loud...

AndrewT - Tannoy have lots of 15" model numbers for different applications which are all pretty much identical. If I remember correctly from before Tannoy changed their website and still had the replacement part numbers listed, the Westminster used the 3833GG.
This is the same as the driver in the System 15 DMTII (3833) but with gold logo on cone, which appears to be same as 3836 used in CPA15 and 3860 in the CPA15FM (which just had a dust cap added - FM = Floor Monitor).
These are all Tulip Waveguide models, ferrite magnets. This was certainly true a year or so ago, don't know if anything has changed since.

Hi again 🙂
Yes, they are complicated, but only the first pair 😎
Like this gentleman:
http://www.hilberink.nl/codehans/tannoy47.htm
I've seen a rectangular "PRO Autograph" somewhere.
I do like better the triangular beauty 🙂
Yes, I read that too. It seems that not all 38XX's are created equal... I asked a local distributor about prices for DC...still waiting for the reply 😡
Bear, do you actually heard GIZMO's system?
I've read this gentleman's review about the Westminster and he became my heroe after he stated he modded the beasts even before he have listened to them!
Maybe an exageration but anyway it speaks about self confidence 😎
Now that he passed away it became my "DIY beginner protector spirit" to which I pray (after the Boss himself) before powering up new projects 😀
I believe, from what I've read and also heard from my tinny Autograph's replica, that the important thing about this kind of enclosure's bass output is its speed and the capacity to reproduce bass armonics well, not quite the depth of it. Any thoughts?
Again, maybe good quality SS gear will be better to achieve the above mentioned qualities.
Cheers.

Why don't you try to contact directly a DIY builder?

Thanks, I did that some time ago, but never heard back from Mr. Green
I listened to Westminster Royals driven by high-end gear at a ritzy audio shop in Manhatten, NY.
I was absolutely blown away.
I used to listen to Klipshorns at the MusicBox in Wellesley Ma when I was at school.
I much preffered the Tannoys -- lots more bottom end.
They say they are down 6db at 18hz in a corner.
I believe it (the Klipshorns barely got to 30hz).

Dear qi :
I envy you 😡 I've never listened to the big Tannoys.
I think in two weeks I will have mine completed.
They will be driven activelly biamped with Hypex' UCD180 😎
Thanks for the .pdf link. I have missed it before. It is OK and only differs +/-1cm here and there from my final dimensions. Most useful is the front horn diagram, wich is a pain to build 🙁
After I recover from the building I will make a 2:3 version 😀 to fit a 8'' fullrange or a 10'' Monitor Gold.
Best wishes.

Hi,
that spec reference to 18Hz was something I found difficult to believe knowing that the Westminster bass horn is truncated somewhat early.
But you just said -6db when corner loaded. That makes much more sense.
However Tannoy's figure implies 18Hz performance with just floor loading. The Westminster were never designed for corner loading, the Autograph was.

Well, according to a guy who sells them, they have to be in a corner to get that low.

There are actual AutoCad plans at that same link I posted.
That is -- the 1st link (at the bottom, and downloadable).
For future builds, you can have them CNCd with the AutoCad plans 😎
Good luck with the rest of it! We are all ears...

I heard a pair of the current (or fairly close) Westminsters a couple of years back, driven by Boarder Patrol valve amps. Sub 20Hz is not a problem. They were fairly near corners, but not rammed right back into them. They need a huge room though.
I love the GRF Autographs. I've a pair of 12in Golds in storage, waiting for the day when I own a room large enough to do them justice. I fancy a modified version of the GRF A cabinet for them. There was a company in the UK that build reproduction cabinets for them a while back -don't know if they're still in business now though.

Hi Scottmoose 🙂
http://www.octave-aw.co.uk/
"Website under revision" it says...I saw their photos.
Excellent work
They probably ask $$$ for them.
I am building Autograph's fronthorn wich is a nightmare
Not very satisfied...
I see Autograph's sex-appeal is not so uncommon 😀 Great!
Golds in storage appear like a sin for this third-world fanatic...sorry to say
That said, I also have to declare that anyone trying to build these enclosures or similar ones is risking his marriage! 😉
Not for the size but for the time and effort needed to do it.
Regards

Thanks for the link. Although the site's not functional, I recognise the name now. Good find!
Would it ease my sins if I told you that they did reside in my living room for a time in 8 foot tall TQWTs? I just don't have the physical floorspace, and the room is just too small to do them justice. That's why they are awaiting a bigger room, so they can be properly appreciated when the time comes. Golds are like a good wine from your fine country -they improve with maturity.

The best time in my experience is when you're living with your parents, they'll put up with it. They will finance too😀
Hi dears:
Oh! 😱 Don't know what TQWT could be but certainly sounds impressive 😀 ... and earns you redemption...
Auto-quote:
I was offered a pair of 10'' Golds for +/-180GBP
Here: http://profesional.beyma.com/producto.php
you can find my coaxial wich is in fact a used 15KX.
I wonder if I can get some serious SPL...woofer handles 300W and 2''tweeter handles 100W, sens. is around 98db/W/m
...and Autographs increases it around +6db
Ciao

Well, I may be wrong there. Yesterday she offered to varnish the inside 😉 for increased strenght and endurance.
I believe you. Thanks for your kind words about my beloved country 🙂 I can help you choose the wright chilean wine 😉 if you need. Here, for 2.5GBP you can have ambrosia

TQWT = Tapered Quarter Wave Tube. A varient form of quarter wave resonator (or TL if you prefer) that's narrow at the sealed end, and wide at the open end, as shown in the excellent render qi has done above of Terry Cain's Bigger Is Better cabinet. (I like the original line drawing incorporated into it BTW).
