Tectonic TEAX25C10-8/SP 25mm High Power 8 Ohm Frog Exciter

I needed a 16 ohm load for a paging system. Used two in series on a ceiling tile and used a T725 transformer for 70v setting, currently on this paging system. Works well. Thank you

Giving this a five star rating because it performs as as advertised - a invisible speaker system!I don't know if these could be considered a great sounding speaker but they do work. We were pleasantly surprised how efficient a pair is (for the small size).
