AlNiCo Gold
That's the question...is there, and what is it?
IME there is not a high watt or low watt equivalent to anything. AlNiCo Blues sound the way they do because of how they are constructed. If you add something to increase its power capacity then the speaker also changes. Try finding a speaker with a 30 ounce magnet that sounds like a EVM 12L. Or a 75 watt speaker that sounds like the old Celestion "green backs" etc. etc. etc. My opinion of course.
