Hi!
I have a pair of Scanspeak 25/W7564 woofers, but the specifications are long lost! 🙁
Does anybody have the specs on these or any good idea where to find them?
Been trying to browse around on the web, but no luck so far.
These are special subwoofer units with an extra spider in place of a dust cap, think they only went up to 500 Hz or so..
Any help is most welcome! 🙂

By chance, I stumbled across some data :
ScanSpeak 25W7564 driver parameters
Fs: 27 Hz
Qe: 0.32
Qm: 3.78
Qt; 0.29
Sensitivity: about 89,5 dB
Re: 6.8 ohms
Vas: 97.3 l
Sd: 298 sq. cm
Apparently, these drivers were from a batch of surplus custom OEM drivers, hence the difficulty in finding the data! 🙂
Anyway, I found (most)of what I was after, just thought I'd post it here to conclude the thread and in case someone else need the data some day.
