My first Tannoy Autograph

maxlorenz · 18th February 2006, 03:15 AM

It was love at first sight

When I first saw the Autograph's enclosure at http://users.bigpond.com/tunnelgap/T...autograph.html

it really made my juices flow. Then, when I began to understand the principle behind (and before) them, I simply was captivated. I had to make them mine!

And now I built my first Autograph:

And another...

And another, showing internal labyrinth...

And finally, a view of my main system:

Do you see them???

Sorry, I couldn't resist!

Now seriously, I made these 35 cm tall Autograph's with a 8 cm AIWA driver that I had here, to practice the building and verifie if dimensions on plans were good.
They are.

In fact, I'm waiting for a pair of Beyma 15'' coaxials that I bought for the real sized enclosures. I couldn't afford true Tannoy Dual-concentric's

The good news is that the tinny 1:4 Autograph sounds unbelievable good for its size! I'm not joking now.

Obviously, with that enclosure and driver size and the low quality of the later it cannot do extreme HF and bass and it's not too clean sounding.
But what they can do is more interesting:

1) the soundstage is amazing (they totally disapear

) with excellent performer's placement and tall, wide and deep image.
2) the rythmic quality of the front and rear loaded enclosure is alarming (no boxed sound).
3) midrange is warm and detailed (considering driver quality)

4) midbass is full, fast and articulated.

Voices are charming, round, colorful and ample. I just listened to Wagner's Parsifal (Knapperstbush; live) and Hans Hotter's voice was rendered without any complaint in all his glorious beauty.

It doesn't matter that it lacks extreme LF because what it does it does with great coherence. All frequencies are created equal

The bad news is that I spent 7 days making these dwarfs. Imagine for the real ones

But it was all fun, I must say.

For the future:
A.- Building of the real Autograph's with Beyma 15'' coaxials and puting them on my "active" system. I think they will be around 100db/W/m sensitive

I will need a better active crossover.

another project.

B.- Building of a 1:2 down-scaled, filterless replica with a Fostex 206E or a Audio Nirvana "super 8". A little "full-range".

Both with chilean oak plywood (very hard and heavy)

Well, I hope these projects interest some DIYers. I feel once more that we were cheated (can I say that?) with conventional speakers.

I love this forum

Interesting excercise.... Untill I realised that that Driver is Headphone Size!
May be a Xerox reduction of a Tannoy Autograph Plan drawing,
but that ..Ain't No Tannoy..
by any stretch of an overactive imagination :-)
The Autograph uses a 15" driver that crosses over at 1000hz then at 300hz on the Horn.. Wonder if that thing even makes the 1000hz range.

LOL !!!

Very interesting job,

for the "real" ones.

pinkmouse · 18th February 2006, 01:07 PM

From first glance at the thumbnails I was totally convinced!

Which plans were you using? I have seen several conflicting versions.

soongsc · 18th February 2006, 01:28 PM

It certainly looks like a nice little speaker. Might be an interesting project for other full range drivers.

Sorry for the delay, I was at the lake

I'm glad my little excercise received some attention.

Actually, 8 cm if we count the surround!

Not at all

Herr Hotter's voice must reach easilly 80hz, I guess. If you prolong lateral wall by mounting on the corner or putting some books, as I did, the sound becomes even fuller.

Dear Moderator:
And they still lack appropriate finish...
The plans are from the exact link that I gave above

I cleaned and edited some, if someone wants a copy...

I'm glad you liked them.

As I said, making an inference from these speakers' behaviour I bet a pair of 1;2 Autograph's with Fostex' FE206E will make the delices of a chamber music lover, like yours trully...
Any comment about Audio Nirvana' "super 8"?

Best regards
Mauricio
