Found a foldback wedge(on verge of house ready for council pick up) with two Australian made Etone 246 drivers in them. They are in perfect working condition.From memory, they sold for around $250 each and are 93-95db efficient.
They have very large magnets and massive cast aluminium frames. Voice coil apperas to be around 2 inches and the surround is pleated cloth.
It took quite a while to dust them off and remove cobwebs etc. Looks like they were kept in someone's garage for quite some time as these speakers have not been made for at least 15 years.
Anyhow, I have just placed them standing(supported) upright in front of open cardboard boxes to kill the rear wave cancellation somewhat.
Sound?..............incredible to say the least. There is plenty of top end information which has surprised the heck out of me!
Naturally they sound big and cohesive - what you'd expect from a full range (?) driver.
After a while, connected to my low power 845SE valve amplifier, you just forget about the speakers and get lost in the sound.
