Compression drivers only. An excellent 2 inch exit driver with the right horn has a spec. from 400hz to 10000 hz. Neo magnets with a five inch composite unique diaphragm. Some in the "horn" business say it is one of the best. Clear, detailed, dynamic. Used for less than 1/2 hour. Decided to not pursue home audio project. Excellent like new. Bought as new about two months ago by self. Remainder of 1 year warranty. Asking $600 for pair. New cost is $756 per pair. Thanks.
