Yes ive just about given up and Ive told them (comet ) that there getting these things back.But Ive decided to stick with piezos and have changed to the 1165 since Ive discovered that its a wide dispersion job 45deg in both planes. In this situation where the speakers have to be hung on rods high up in the corners of the room there may be a distinct advantage to using them. after all frequency response off axis is a joke in most tweeters ,even expensive ones.Incidentely I can get these kn1165 sourced from Monacor I believe for 3.00 Pounds each locally. wish me luck.
