Utah 18" driversw/ alnico magnets

Utah used to oem relatively inexpensive raw drivers for trusonic (among others). Commendably they insisted on using alnico for the magnets (an excellent thing to do, and nowadays very expensive). They also offered speakers I think...
SO,
The answer to your question is, it depends on price, the CONDITION of the drivers, and yr needs.
If the woofs especially are in good condition (check surrounds, noises, etc), you have use for these drivers, and are interested in tinkering with the speakers, then go for them. After that it's a matter of price.
18" alnico are expensive nowadays, if that's anything to go by... and some trusonics (possibly manufactured by Utah) fetch quite good prices on e-bay.

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.

Eldartford: "Why is (alnico) such a big deal today" Mostly because it's expensive now and not very commonly found in drivers.

Gregm...Dirty little audiophile secret!! If it costs a lot it must be good.
