Default Speaker specs

Recently I was asked to enhance an electronic "Heyligers" organ. The amplifiers (10) need replacement but there seems not to be any technical information so I have to browse the net for the spec of the speakers first. I mailed Philips but they are not able to help.
I found the specs of AD 12100/M8 (2422 257 51003) here on the forum, so maybe someone knows the others aswell.

AD 1265/W8 (2422 257 31202)
AD 1265/M8 (2422 257 41102)
AD 9710/M8 (2422 257 48101) (Specs I found are different on power)

Please help me out!

Thank You Martin!

So now I have an AD 12100 midrange at 25(45) Watt,
the AD 9710 midrange at 15 Watt,
and the AD 1265 M8/W8 midrange/woofer still unknown.

The AD 1265 M8 is mostly used with the AD 9710 in paralel with a spacing of about 2 meters. This gives a nice impression of "pipes" placed in the organ.
So now max power is limited to 15 Watt for eight pairs.
And the AD 1265 W8 (with Praestant 8" and Gedeckt 8") and the AD 12100 (with Fagot 16" and Subbas 16") at a max of 45 Watt.

I have to start a new thread in the amps now.

Thanks again, Jan.
