They don't look "run of the mill" to me, but Gordon would know for sure. I'm just not familiar with Utahs....Sorry zilch, thats the add on i was talking about, someone sawed out for the speaker wire clip ons. I will get another pic of the back. Another question, i read that when utah made the drivers for altec, they were custom built just for this particular model. Is there any truth to that? Or are these just the run of the mill utah drivers? I can pull one out and take a pic if you wanna see them.
