Description

Special order. Confirm supplier availability and lead time before ordering; not represented as local shelf stock.

  • Pair of 165 mm high-end coaxial speakers with separate woofer/tweeter connections
  • 150 W RMS / 225 W maximum system handling
  • 3-ohm midbass drivers and 4-ohm silk-dome tweeters
  • 50 Hz–30 kHz published response
  • UHD paper midbass cones and 37 mm voice coils
  • 65.8 mm mounting depth; 142 mm cutout

This is not a conventional single-input coaxial speaker with a built-in crossover. Active operation requires two appropriately filtered amplified DSP channels per speaker, four for the stereo pair, with essential tweeter high-pass protection. Alternatively, use the separately sold compatible HELIX Ci7 FX-UNI.2 passive crossover pair. Never connect the tweeter directly to an unfiltered full-range output.
