I just bought a pair of these:
http://cgi.ebay.co.uk/ws/eBayISAPI.d...m=160952299983
Full range 8 ohm 8" 10 watt drivers with 94db sensitivity selling at £6.25 a pair.
They actually measure around 7.9 ohms DC, which means they are nearer 10 ohm drivers really. I can see two pairs in cheap home built reflex cabinets making rather useful party speakers. Gives you 5 ohm, 20 watt rating per pair @ 97db efficiency producing over 110db at max. That's loud! And nobody's going to notice the lack of proper deep bass.
The magnets are tiny, they are a little coloured, but definitely a bargain!
