SC 13 - 8 Ohm

Art. No. 8013

Magnetically shielded 13 cm (5") HiFi fullrange driver with cellulose cone and rubber surround. Can be used as a low-midrange driver too. Due to the very balanced frequency response especially suitable for magnetically shielded 2-way speakers for multi-media and surround systems in conjunction with the shielded tweeter SC 10 N - 8 Ohm.

Typical applications

  • Surround centre speakers
  • Multimedia systems
  • Video monitoring screens
  • TVs
  • Computer terminals
