WHY IT EXISTS
Hide the cabinet, not the system intent.
IW300 brings the 300 Series into a fully architectural format, useful when the room finish demands invisible loudspeakers.
As with any in-wall reference speaker, framing, cavity construction and service access need to be treated as part of the acoustic design.
SYSTEM ROLE
Where it fits in a cinema.
Architectural surrounds
Useful for side and rear positions where projecting cabinets are undesirable.
System consistency
Keeps the main channels inside the same M&K family.
ROOM DESIGN
Choose the room conditions before choosing the quantity.
Wall constructionDo not assume every stud bay provides the same acoustic environment.
IsolationControl vibration transmission into adjacent rooms where possible.
PlacementThe wall fixes the speaker position permanently, so geometry must be right before plastering.
