Description

The ROSSO-12CX350 is a 12" professional coaxial loudspeaker from SB Audience's Rosso range, built for high-output applications. It combines a low-frequency woofer and a high-frequency compression driver in a single unit, for seamless integration and wide dispersion.

Features

  • Cast aluminium chassis and HF rear chamber
  • Integrated high precision machined HF horn
  • Common HF/LF ferrite magnet motor structure
  • Minimum damping fibre glass voice coil former
  • Ribbon voice coil wire for high efficiency of HF section
  • Additional support Neo slug magnet on pole piece for higher SPL
  • Weather-proof coated paper cone made in house with sisal and manila fibres
  • Requires crossover

  • Xmax is quoted one-way (peak), not peak-to-peak.
  • Sensitivity measured at 2.83V/1m.
  • On this coaxial, the Thiele/Small parameters are the woofer's; the tweeter's are listed separately.
  • Power handling (RMS) is the AES rating: 2 hours of pink noise (6 dB crest factor), Fs to 10 × Fs, in free air, on the minimum impedance. Program power is SB Audience's maximum power, 3 dB above the RMS rating.
  • Sensitivity is averaged over 150 Hz–2 kHz.
