Pair of classic Scan speak D2905-9000. Good condition, not perfect as some mounting hole scuffs. One lead a little short but have wire leads safely soldered (dont overheat) with male 1/4 fast on connectors. Resonant Fs measured around 780 which is within spec (800). Also response matches near manufacturer with the mild inaudible dip at 4.5-5KHz ish. The rise at end likely diffraction/reflection from 9 inch baffle mounted on for measurement. Smooth, robust tweeter. Not knowledgeable of speaker driver lore to say what differences with current models are.

Excellent quality Pr Scanspeak D2905/970000 Dome Textile tweeters. They are nominal 6 ohms, both measure 5.5 ohms. See the impressive specs below. They are in nice working condition, a few of the screw holes show some wear, nothing serious. They were always in a non smoking climate controlled environment. The shipping cost includes safe packing, insurance, prompt shipping and tracking number. They were quality made and designed in Denmark, incomparable quality design, craftsmanship and performance. Buy with confidence, see my feedback. Good listening, SonnY :) ScanSpeak Classic D2905/970000 1? Tweeter Textile Dome1?

The Symmetric Drive technology eliminates almost all electrical phase shift. The carefully machined top plate minimize air noise and compression. Copper caps act as heat conductors. High power handling is achieved without ferrofluid and improves micro-dynamic linearity. The tweeter has excellent dynamic and detailing capability.
