3/4" critically treated textile dome, multiple tuned rear chambers, no ferrofluid, hermetically sealed enclosure, damped faceplate. Excellent detail resolution, imagery and smoothness. This tweeter is the non - ferrofluid version of D2010/851300, both have exceptional dispersion & are firm favourites with high end manufacturers.
This unit has been in production for more than 3 decades and is still a benchmark performer ~ testimony to the excellence of drive units associated with design supremo Oskar Wrønding.
