Krix KX4010.S Cinema Stage Subwoofer


Cinema shallow stage subwoofer loudspeaker featuring a single 18" bass driver enclosure with large vent areas, which are a feature of Krix subwoofers and are vital for efficient low frequency radiation at high power.

The KX-4010.S is a high performance, single 18" subwoofer. It has been designed to give maximum SPL down to 28Hz and in such a way to reduce cone excursion in the pass band (above 27Hz).

Large peak to peak linear cone excursion and large vent areas, together with the correct enclosure volume and tuning, have all been optimised to give large linear power response at all frequencies. That is, little compression occurs at high levels at very low frequencies

  • Linear power response
  • 15mm peak to peak linear cone excursion
  • High efficiency
  • Large vent areas
  • Enclosure depth standardised to 380mm same as KX-2610.S
