hi, my name is Hannes.

i found this site when i was searching for diy plans for some speaker boxes.

i have some wierd speakers in my posession. they come from a school pa system and they look old. i have 10 of the same.

Welcome to the forum,

Those are Philips alnico FRs . The attached transformer is an impedance matching transformer (today it would be 70V). The trafos are likely not much use, but the speakers are worth playing with. They are likely hi Q, so an open baffle would be the 1st suggestion for loading, with 10 you could do a 1.5-way or a 2-way system with 1 as FR (or midtweeter) and the over 4 to help down low,

Hello Hannes and welcome to the forums

thx for the help. I dusted them all off today and it seems that only 4 looks to be in somewhat good condition. The other 6 don't look so much for this world anymore (i suspect that my cats has been playing with them)
