actually, I have a low watt Tunsten T15Q, 20 watt, 8 ohm speaker. Its Weber made to Tungsten specs. Its alnico, sounds like exactly what your looking for. I got rid of my 15" combo (like a schmuck) http://www.tungstenamp.com/speakers.htm
I'm looking for $80 plus shipping. It goes for $140 new.
Let me know if your interested. firstname.lastname@example.org
