My first Tannoy Autograph

[Zen Mod]

if possible - try to choose drivers which don't need any zobel ;

when you mount that drek on any driver and compar them - both with drivers which don't need that , and with same driver previously to zobel - magic is gone .

this sport is brutal and gentle in same time , so don't spoil it with bad choices - just take your time and spend your money wisest you can , even if that means tthat you must wait for best drivers time can bring in your direction

best - meaning - better ......

Actually, the zobel--a simple R/C network--sounded fantastic on this particular driver. It didn't spoil the magic, and I do know what you mean by magic. The driver just became smoother sounding, with the same crisp highs and forward vocal region. I ran these 10s in a T/L, if that makes a hill of beens to anyone.

Unfortunately, the Audio Nirvana series above the Cast 10 has high Qts, much too high for my future horn.

Rest assured, I'll be looking hard for the right driver.

Thanks for the suggestion, all the same.

For a full size Autograph, if I had the money, I would go for the very attractive P Audio BM15CX38, which are also offered at commonsenseaudio.
It has also a 2inch HF unit, like the Tannoy (and my humble second hand Beyma).

An AN15 would need the help of a superTweeter, I guess...

When this nightmare period/year ends, I will build my dreamed corner enclosures: modified Autograph for a full-range fullranger ANsuper10. The project is in suspense...

My first front and rear horn loaded fullrange design: help needed from The Wise.

It would be modular in the development phase and asymetric in shape, to point to my sitting position, tailored to my other living-room which is 3,3m in width.

I've considered the P Audio unit, but can't locate the T/S parameters. Without those, I'm not going anywhere near that driver.

The AN15's Qts is too high, and the coaxial unit is higher still.

The AN Cast 10 is a good choice Qt wise but is a bit shy on bottom end. What to do, what to do? I've thought about creating a front horn with a 20 inch vertical slot and using two different 10 inch drivers--one with bass and a full ranger stacked above. I don't know if that's ever been done. I've seen a unity horn with one bass driver facing the throat and four smaller high frequency units bolted on the four sides of the throat. They load the throat of the horn through small holes. At the time, it seemed an interesting experiment that one day I might try--perhaps the time is now?

For some reason, I can't expand your drawings, Max. It's rather frustrating to read a thread and not be able to see the graphics--and I'm sure you put a lot of thought into those drawings.

I have here the chart of the Beyma 15KX but can't find the complete one for the P Audio. I found this:

Speaker City sells speakers, drivers, audiophile loud: 15 in. Coaxial 700 watts 8 ohms

...that can help. Maybe if you email Mr. Dicks from commonsenseaudio; he can have the complete ones with response curves. I've seen those and the HF can do lower than 1000Hz.

About the project speaker: it will be made by "ear and intuition"

Good luck.

Excellent link, Max! P Audio looks pretty good from here. I like the P Audio CXA series as well, and for much less cash. I wonder if there's a performance graph out there, somewhere.

Google is your friend (for now)

P.Audio Coaxial Speakers - P.Audio BM15CX38 coaxial 15" speaker - P.Audio BM15CX38 500 watt 15" coaxial speaker for all full range applications. P.Audio BM15CX38 15" coaxial and other P.Audio coaxial speakers here.

This auzzie has a pair on sale (Australian dollar)

I'll search my database when I get home.

maxlorenz,

Once you mentioned Westminsters... Any idea how to build them? A friend of mine is finishing GRFs (not the first one) and he's capable to make Westminsters but their plans are missing.
Can you help somehow? I have Tannoy Golds 12" and I do want to make Westminsters.

Thanks
