WHY IT EXISTS
The middle ground between compact cinema speakers and full-range giants.
P28 Mk3 is intended for large rooms where the screen channel needs significantly more headroom than compact models but the project cannot accommodate a much larger full-range cabinet.
That makes room depth, listening distance and reference-level target the right way to decide whether it belongs in the project.
SYSTEM ROLE
Where it fits in a cinema.
Large rooms
Designed around long listening distances and high peak SPL.
Baffle-wall mounting

ROOM DESIGN
Choose the room conditions before choosing the quantity.
MountingProcella recommends vertical orientation and wall/baffle integration.
Bass managementDecide how the front stage will hand over to the dedicated low-frequency system.
Amplifier headroomHigh-output speakers only deliver their potential when the electronics can sustain the peaks.
