CoActual technology

  • Combines DSP time-correction and point-source design for symmetrical soundstage and micro-definition imaging 
  • Unique coaxial transducer integrates 8-inch (Sceptre S8) or 6.5-inch (Sceptre S6) midrange driver and 1-inch (25 mm), horn-loaded HF transducer with Coaxial Speaker Coherence Alignment 
  • Powerful DSP provides critical Temporal Equalization™ with multiple FIR filters 

Acoustic-tuning controls

  • HF Driver Adjust (0 dB, +1 dB, -1.5 dB, -4 dB) 
  • Acoustic Space settings (0 dB, -1.5 dB, -3 dB, -6 dB) 
  • High-pass filter (Off, 60 Hz, 80 Hz, and 100 Hz, -24 dB/octave slope) 
  • Sensitivity (+4 dBu to -10 dBV) 

Power and safety

  • 180W RMS, Class D biamplification with internal heat sink 
  • 102 dB maximum continuous SPL
  • RF shielding, current-output limiting, and over-temperature protection 
  • Amplifier “soft start” feature eliminates popping on power-up 
  • Internal power supply with IEC connector 
  • Power switch with on/off LED


Inputs and outputs

  • Balanced XLR and ¼-inch TRS line-level inputs with A-taper level control
