A year ago I purchased the drivers for the N90. I was disappointed with the lack of bass and lack of high frequencies. In the midrange they were pretty good. Not worth the money I paid. They then were twice the price they are now. Also one of the drivers has failed for an unknown reason two weeks ago.
