Utah 18" driversw/ alnico magnets

Anyone have any info on Utah 18" drivers? I think they were manufactured in the mid seventies and had Alnico magnets. I think they were also used in Trusonic speakers from the mid 70's. I found a pair of custom project speakers that have the Utah 18' drivers with a 4" mid range and a high frq. horn. Would theses speaker be worth looking into?
Thanks

Gregm...You say "Commendably they insisted on using alnico for the magnets". I don't understand the "Commendably", because as I remember the 50's all decent drivers used Alnico. Why is it such a big deal today. I believe that various other magnetic materials are stronger.

I hope that someone is not goint to tell us that Alnico Gauss are different from ceramic Gauss (like tube watts and ss watts).

Utah was big in the PA system business.
