This is my first post in this forum. I just picked up a pair of Fostex SP11 MK II PA speakers for $10.00. I figured I could do something with them. Even with the 2 drives per side they are not very efficient at 92db@1w/1m. Sill not bad for small drivers. It appears that Fostex does not even sell these in the US but I found the specs on the international Fostex site (see link).
The drives in them are model 10F07C and are 16ohm 10cm full ranges with stamped stell baskets and have big magnets for a driver of its size. The cone appears to be paper with a foam surround. The cabinets a molded plastic(?) that is comon for pro speakers. They have a switch on them for different equalization cuvers for voice and music.

It didn't sound bad with the old Sony receiver I used to test it and the switches set on music. A lot of base was kicking out the port. You could feel it pulse with you hand, but this is definately not a base heavy speaker. I was thinking of trying it with a 12" M&K subwoofer that I have. Im not sure about the idea of a pair of horozontally mouted woofers angled slightly out from each other per speaker but I'll give it a try.

I was wondering is: Are these divers 16ohm verisons of Fostex 107 drives?

Are there any suggestion of what to do with these that don't involve sensitive parts of my anatomy? (Ears are ok!) Any info would be helpful!

TIA
