19mm Fabric Dome Treble
D2010/8511 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 also features a multi-layer faceplate, which is designed to reduce mechanical resonance and the concave back plate ensures rigidity.
The D2010/8513 is one of Scanspeak's Classic treble units and has been used in the past, by many commerical manufacturers such as Naim, ProAcand Spendor.
