- Installations with the space and handling plan for two 74 kg chassis
Consider it when

ARCHITECTURE
Understand what each feature means in a complete system.

SYSTEM / ROOM MATCHING
Will it fit the system you already own?
We consider connections, room context, installation and your listening priorities together before suggesting a configuration.
What to check for your system
- A stereo installation requires two chassis, dedicated support, ventilation and cable planning
- We check gain, input impedance and loudspeaker load before recommending this model
What to keep in mind
- One M500 powers one channel, so a stereo system requires a pair
- Australian availability and expected delivery timing require confirmation
