Can someone help me understand how external speakers can be connected to a Bolex SP-80? Is an amplifier mandatory for external speakers? What specifications should I look for on a speaker?

Any information will be very very helpful.

Too many recent posts and this post of mine was perhaps. Am still looking for guidance on this issue.

This projector can use ANY external speaker with an impedance of 4 ohms (or greater) and capable of handling 10 watts RMS power.
The projector should have a 2-pin DIN socket which switches off the internal speaker when the plug is inserted.
If a speaker that you have is not fitted with a 2 pin DIN plug, they van be obtained from places such as Maplin in the UK, extensively in Europe, and, I understand, from Steve Osborne of Reel Image in the US.
