The Infinity REF9620CX is a 6×9 2-way component speaker system that includes two woofers, two tweeters, and two passive crossovers. Woofers use Plus One+ polypropylene cones with hi-roll rubber surrounds for extended bass output and the system delivers 125 watts RMS and 375 watts peak with a frequency response of 46-21,000 Hz and 93 dB sensitivity.

Tweeters are 3/4 inch edge-driven textile domes and mount using Infinity I-Mount or Starfish brackets for surface, flush, or factory grille installations. Crossovers provide selectable tweeter output levels (0 or +3 dB) and use screw terminal connections; the 3 ohm nominal impedance is intended to extract more power from factory or aftermarket receivers with small-gauge wiring.
