I agree with the above. The Dunlavys excell with high quality amplification and sources, but will pretty accurately reproduce what they are fed. One other possibility is your room--is it untreated with reflective surfaces at the first reflection points? That might have something to do with the sound as well. And how big is your room?
My dunlavy scV sound harsh
I have a set of Dunlavy SCV, Proceed 250/channel and an Onkyo pre/pro. The sound is glaasy, harsh. Do I need to replace the tweeter?
