PSI AUDIO · AVAA C214 ONLY
AVAA C214 is a pressure-based active bass absorber operating from 15 to 160 Hz. It is particularly relevant where deep-bass passive treatment would require substantial depth or surface area, and where measured evidence shows excess resonance or slow decay. It is not a phase-cancellation device and it is not a universal remedy for missing bass or a deep null.
Frequency-response and decay measurements help establish whether AVAA addresses the problem you actually have.
A page cannot determine the number of units, their placement or the treatment outcome in a particular room.
MSN Audio currently focuses on AVAA C214. If you are looking for a PSI studio monitor, contact us so we can confirm whether we can assist.
ACTIVE BASS CONTROL
The page explains the product facts and the room evidence worth measuring. Your room, placement and quantity still need to be assessed rather than predicted from a product page.
PSI AUDIO · ACTIVE BASS CONTROL
AVAA C214 is built for the bass that keeps ringing after the note should have stopped. It actively absorbs low-frequency room pressure from 15–160Hz without being inserted into your music signal path.

A Melbourne Room & Bass Measurement can identify the bands and decay behaviour that deserve attention without presuming AVAA is the answer.
The AVAA C214 page separates manufacturer facts, room-dependent implications and what still requires measurement.

At low frequencies, a room may continue storing energy after the musical event has stopped. The audible result can be one-note bass, overlapping notes, reduced clarity and congestion as playback level rises.
AVAA C214 is a pressure-based active absorber operating from 15 to 160 Hz. It works in the room rather than in the main music signal path and is particularly relevant where passive low-frequency treatment would require substantial depth or surface area.
02
A deep cancellation, missing bass at one seat, poor source/listener geometry or incorrect subwoofer integration may require placement or additional low-frequency sources rather than more absorption. AVAA C214 is not a phase-cancellation device and does not fill every null.
For that reason, MSN Audio does not recommend C214 from symptoms alone. If the problem has not yet been measured, a microphone-based assessment is the clearest place to start.
03
The paid Room & Bass Measurement identifies major peaks, cancellations and decay behaviour. If the result and room are suitable, a C214 demonstration may be arranged as part of the assessment or follow-up process. Demonstration availability is confirmed before the appointment.

Clients outside Melbourne may enquire about current Australian pricing and availability. Tell us about the room and the problem you want to solve. We use that information, and local measurement where needed, to discuss quantity and placement without asking you to guess.
