Well I have had the combo of Fosters meets DX25 for a while now and must say I'm just not impressed with the tweeters low end distortion. I used the ART array crossover and found them quite fatiguing. I was however able to not biamp.which was easier. Do the DX25's take quite a while to break in ? I used my behringer active crossover too but I just can't get anything I can enjoy. Maybe it's time for smaller woofers in my array of ND tweets.
