Default Dynaudio kit plans

Dear friends.
I'm in urgent need of the old Dynaudio speaker kit plans....All
models if thats possible.
I used to be the Sole agent (oem) for Dynaudio here in Adelaide South Australia,and had the plans for .....everything dynaudio.
sadly they have walked and i cannot replace them.
If anyone can help me i will be more than willing to share my expertize with you.
Myself and a good friend of mine designed world class Loudspeakers using Dynaudio and Morel drivers for Duntech Audio some 7 years ago.
My knowlage in complex first order filter design should be help to many here in the forum.
Kindest regards.
racoon.

Your Welcome ! , and Yes I'm way down south from you - Woodcroft.
Could I draw on your vast experience and ask if you know what the value for Rs should be in the Sirius crossover ?
see here : http://www.gattiweb.com/images/dynaudio/sirius4.pdf

Cheers'
Andrew

No worries mate.
The values your looking for are as follows......High frequencey roll of..2.2 ohms 5watt/15 ohms10watt.

Normal 1.2 ohms 5watt15ohms10watt

high frequencey emphasis 1.2 ohms 10watt...omit 15 ohm resistor.

extreme high frequencey emphasis omit both resistors.

Andy these are the values recomended by Dynaudio.
hope this helps mate.
Rod.

There's some of the kits here too......
http://www.geocities.com/CapeCanaver...091/dyna2.html

raccoon : Do you have any suggestions on a way to replicate the variovents in the Sirius ? Given that its nigh on impossible to get them from Dynaudio and they're only described as "white" and "yellow" versions .
I can make the vent physically but not sure on what foam to stuff them with..........

Andrew

Default help with Foccus resistor values

I am experimenting with some old Dynaudio drivers and different crossovers. The Foccus crossover is working pretty good, but I am only guessing at the Rs and Rp values. Does anyone have the factory recommendations? Thanks
