Absorb bass energy in the room
C225 responds to low-frequency pressure and absorbs acoustic energy in its operating band. It works independently of your playback signal path, with no audio connection to the system.

PSI Audio AVAA C225
When powerful cinema bass lingers too long.
AVAA C225 provides active bass absorption from 12 to 130 Hz for home cinemas and high sound-pressure environments. It works in the room without an audio connection to your playback system. Measurements help establish whether it suits the problem you hear.

ACTIVE BASS ABSORPTION
How C225 handles bass in the room
Capacity for powerful bass playback
Two 10-inch drivers and active control provide absorption headroom for home cinemas and other high sound-pressure environments. That capacity is a reason to compare models, rather than a prediction of the improvement in your room.
When to consider C225
Consider C225 when lingering bass is a concern in a powerful home cinema, or when a high sound-pressure studio or small club needs more absorption headroom. The listening problem and available space help guide the choice.
MODEL CHOICE
Choosing between C214 and C225
Compare your usual playback level, the measured problem and the space available. Room size alone does not determine the model, quantity or position, and the larger model is not always necessary.

ASSESSING THE BENEFIT
How to judge its value in your room
Describe what you hear before choosing equipment. Measurements and a controlled comparison can help distinguish a useful change from a change in level or listening position.
What to assess
- Start with the bass notes or film passages that linger, your usual listening level and the seats that matter to you.
- Measurements can examine frequency response and decay. Where a C225 comparison can be arranged, compare the same material, level and positions with absorption on and off.
What needs confirmation
- The useful change in response and decay depends on the room. An absorber does not extend your system's bass response or resolve every cancellation dip.
- This describes how to assess suitability. C225 demonstration or trial availability requires separate confirmation.
ROOM MEASUREMENT
Discuss the right scope for your system
For home cinema or systems with multiple subwoofers, confirm the measurement scope and quote before booking. The listed two-channel service packages do not automatically cover these systems. Product purchase is not required.

FAQ
Before you choose C225
Do I need C225 if I already use room correction or EQ?+
EQ changes the playback signal; C225 absorbs acoustic energy in the room. Having room correction does not establish whether you need C225. First assess any remaining bass problem, then use measurements and a comparison where available to judge whether active absorption adds useful value.
How many units will I need, and what is the total budget?+
The listed price is per unit. Floor area alone cannot determine quantity or placement. The measured problem, listening area, playback level and practical positions guide the assessment. Confirm the model and number of units before calculating the total equipment cost.
What improvement should I look for, and how can it be checked?+
Assess whether the bass that lingers becomes less intrusive, alongside measured changes in frequency response and decay. A useful comparison keeps material, level and measurement positions consistent. No fixed improvement is promised, and active absorption cannot resolve every cancellation dip.
Does it need an audio connection or tuning to individual frequencies?+
C225 works acoustically in the room without an audio connection to the playback system. It operates across its specified band without tuning to individual room modes and supports App control. It absorbs bass energy rather than reproducing a soundtrack's bass channel.
How do I order, and can I arrange a C225 demonstration?+
A$11,999 per unit including GST. Send an enquiry and we will confirm current stock and delivery timing before payment. C225 demonstration arrangements need separate confirmation.
What warranty applies?+
PSI Audio states a five-year warranty for component and manufacturing defects, with one additional year after product registration. The manufacturer's warranty terms and Australian Consumer Law rights apply.
