Hi.
I have 2 24" drivers supposed to be the first driver in the Turbosound 124 (?) frontloaded horn. They are dated 1987.
It has a very thick white polypropylene cone.
I measured both the drivers and it ended up like this:
Re: 6,38 - 6,47 (D1 - D2)
Fs: 24,2 - 23,55
Qts: 1,015 - 0,94
Qes: 1,241 - 1,138
Qms: 5,581 - 5,401
Le: 2,436 - 2,376
Mmd: 401,5 - 448,8
Vas: 582,1 - 550,8
Sd: 1963
BL: 18.04
My guess is that X-max is ~6mm.
Does anyone have any info about this speaker ?
It seems to me that a frontloaded horn with this will have a huge peak.
I simulated it in HR and maybe it´s supposed to peak, a part of the idea ?
Best regards.
Figge.

🙂 Thanks jogi. Thats the one.
Now I´m wondering how much a long storage may affect the driver parameters.
I measured them with Dats. Maybe its not correct ?
Best regards.

I wouldn't expect any/hardly any change, if the suspension changes that drastically then it will likely be that it is from material deterioration and will subsequently tear itself apart when you apply a bit of power anyway.
