19mm Fabric Dome Treble
D2010/852100 is a coated textile domed tweeter with a very smooth response and wide dispersion. It's superb sound reproduction is detailed and very dynamic. The optimised double chamber design provides perfect tuning and damping, whilst the acoustic damping of the diaphragm surround, reduces distortion and stabilises the acoustic centre.
The D2010/852100 also features a multi-layer faceplate, with a diffraction damping cell rubber front, which is designed to reduce mechanical resonance and the concave back plate ensures rigidity.
The D2010/852100 is one of Scanspeak's Classic treble units and is an ideal replacement for use in many commerical speakers, such as Naim, ProAc and Spendor.
