Unlock full midrange tone in compact pillars.

VX Aentra™ Aperiodic Vent lets small enclosures behave like larger, well-damped volumes—reducing resonance, smoothing response, and improving vocal body without sacrificing staging.

How the Aperiodic Vent Works

A sealed pod stores pressure. With limited volume, resonance rises (high Qtc). VX Aentra™ adds a resistive vent—not a bass reflex port. Acoustic resistance converts pressure to heat in the media, adding damping so the system behaves like a larger, better-damped enclosure.

Why VX Aentra ≠ Simple Free-Air Holes

Free-Air Holes

  • Uncontrolled leak—air moves freely in/out.
  • No acoustic resistance → high, unpredictable Q.
  • Acts like a tiny reflex port: uneven midrange & phase issues.

VX Aentra Vent

  • Engineered resistive vent converts pressure to heat for controlled damping.
  • CLIO-verified Qeff ≈ 0.6–0.7—behaves like a larger, well-damped sealed box.
  • Individually matched pairs for stable stereo imaging.
  • Serviceable media lets you fine-tune resistance without altering the pod.
