The Magnum Opus of Time-Domain Accuracy | Available at Trimira Audio
The Wilson Audio WAMM Master Chronosonic represents one of the most ambitious loudspeaker designs in high-end audio, developed around the principle that exceptionally precise time-domain alignment is fundamental to realistic spatial reproduction.
Created as the culmination of Dave Wilson's loudspeaker-development work, the WAMM Master Chronosonic uses an open modular architecture with independently adjustable driver modules. This allows the acoustic arrival time of individual transducers to be precisely configured for the listening position.
At Trimira Audio, we recommend the WAMM Master Chronosonic for uncompromising reference systems where spatial precision, dynamic realism, and extreme low-level resolution are the primary objectives.
Key Features & Technological Innovations
Micrometric Time-Domain Alignment
The defining feature of the WAMM Master Chronosonic is its precision mechanical adjustment system.
Individual driver modules can be positioned independently, allowing their acoustic arrival times to be carefully aligned for the listening position.
This architecture is designed to provide exceptionally precise temporal integration between the multiple transducers.
Full-Range Dual-Woofer Architecture
The low-frequency section incorporates:
- 10.5-inch upper woofer
- 12.5-inch lower woofer
The drivers operate within a cross-load flow-ported enclosure designed to provide extended bass response while maintaining controlled transient behaviour.
QuadraMag / MTM Midrange Array
The midrange architecture uses a symmetrical arrangement around the tweeter:
- 2 × 5-inch upper midrange drivers
- 2 × 7-inch lower midrange drivers
The MTM configuration is designed to provide controlled vertical dispersion and smooth integration through the critical vocal and instrumental frequency range.
Dual Convergent Synergy Tweeter Array
The WAMM incorporates both a forward- and rear-firing tweeter.
The rear-firing ambient tweeter can be adjusted to help tailor the amount of reflected high-frequency energy to the room's acoustic characteristics.
Advanced Composite-Material Construction
The modular enclosure and gantry employ Wilson Audio's proprietary material technologies, including:
- X-Material
- S-Material
- V-Material
These materials are used to control cabinet vibration, mechanical energy, and unwanted resonance throughout the loudspeaker structure.

Amplifier & Room Matching
The WAMM Master Chronosonic presents a demanding electrical load, with a specified 3-ohm nominal impedance and 1.77-ohm minimum.
Consequently, amplifier selection should prioritise:
- High current capability
- Stability into low impedances
- Substantial power reserves
- Excellent transient response
- Appropriate system gain structure
The loudspeaker's extensive mechanical adjustment capability also makes professional installation particularly valuable.
Time-Domain Setup
The WAMM's performance depends heavily on correct physical alignment.
Trimira Audio can assist with:
- Listening-position measurement
- Driver-module alignment
- Vertical and horizontal positioning
- Rear-tweeter adjustment
- Room-acoustic assessment
- Amplifier matching
- System gain calibration
The objective is to configure the loudspeaker around the actual listening position, rather than relying solely on generic factory positioning.
