FFL’s Tannoy K3809 adventure (revitalization ………. again !?! )

My friend , known around as FFL ( younger  of two wakoo brothers from Nagybecskerek ) , brought a pair of , well , pretty beaten up K3809 Tannoys ; They’re having new HF diaphragms, but surround is long ago in rock solid form …….. well above 60Hz .

There were also few more problems – suspicious bass VC centering on one at least , sorta tired cones and ugly gaskets …….

I didn’t took any pic prior to dismantling magnet assemblies from baskets , but there will be few pics of drivers from above , prior to finishing steps , so you’ll have some insight in their condition , as they arrived on my bench ……..

 

Read picture captions for detailed info .

Another Tannoy K3809 adventure (read – revitalization , again ) – 3 previous episodes cumulative , with finish

It started due to adventurous spirit of Ninja ( as known on Baby DiyA ) – he found them somewhere on web adds , I believe in Denmark .

As he said – “I don’t know do I need them , but somebody will “ ; due to fact that one is reported as having de-centred bass cone , they were pretty decent price-wise .

Pretty benign pictures , sent to Ninja from seller ; half-luck – just one is having K3809 type sticker , but both are no-back-ribs …… we were hoping in that moment that no-name one is not K3805 (higher Fs , used in Puma cabs) :

Another Tannoy K3809 adventure (read – revitalization , again ) ….. Part 3.

Continuo from previous post .

Up to removing old hardened surround impregnation . Entire procedure is already explained here, but I’ll try to illustrate it and explain more thoroughly .

What you need is :

– Alcohol (Etanol) 96%

– cotton rug

– small container for Alcohol

– small brush ; that sort which is bad for any painting , but perfect for purpose – around 10mm wide , plastic threads – so it is semi-hard ….. perfect for applying some force , which we really need here .

Big Tannoy Open Baffle fun …… playing with test xover

Continuo from here ;

Still without measurements , just playing with data from various web sources , LTSpice and bunch of parts

 

Tannoy Open Baffle fun …… brute force approach

K3809 as main driver , K3833(K3836) as bass helper

K3809 are mine , while K3833(K3836) , stars of previous blog entries  are prepared for SuperFi’s Westminster project .

Just having fun with some old OB “wood” , gift from Chakija ( he’s not feeling young enough to continue playing with them 😉 )

Disclaimer – I really wasn’t expecting real bass ……. that’s max width I can squeeze in living room , where spks must be situated ; also , MJK OB software didn’t predicted it (bass)

But !! – there is bass , at least in my smallish living room ; sound is remarkable , even with crude and quick xover , without any efforts put in measurements and polishing of same ; OB is far from optimal in almost every area , but it is so fun …..
