Description

The SC 10 N has a coated fabric dome for a linear response and a ferrofluid-cooled voice coil for high power handling, with a shielded magnet system for use close to a screen. Visaton's suggested partner is the shielded SC 13 low-midrange driver. This 8 Ω version takes 100 W with a 12 dB/oct. high-pass from 4000 Hz and resonates at 1700 Hz.

Typical applications

  • Tweeter for two-way hi-fi speakers
  • Magnetically shielded centre speakers
  • Multimedia and computer speakers

Installation and cabinet guidance

Allow an 85 mm panel opening. The round faceplate is 104 mm in diameter, with 3.9 mm fixing holes on a 93 mm circle; mark them from the unit itself rather than assuming the spacing. Behind the panel allow about 33.5 mm for the 84 mm rear housing, plus room for the terminals and the wiring.

Mount it on a rigid baffle with a continuous seal between the faceplate and the panel, tighten the fixings evenly and only enough to seal so the faceplate is not distorted, and keep the dome clear of any grille. It is heavy for a dome tweeter, so make sure the baffle and the fixings can carry it. Connect to the 4.8 x 0.8 mm (+)/2.8 x 0.8 mm (-) blade terminals with matching push-on connectors and observe polarity; the two blade widths identify it. The power ratings apply only with a 12 dB/oct. high-pass filter from 4000 Hz, so feed it through the system crossover or a high-pass filter that gives at least that protection; never connect it directly to a full-range signal. Use an amplifier suitable for the 8 Ω load. The driver is magnetically shielded, so it can be used in centre, multimedia and near-screen speakers.
