WHY IT EXISTS
A smaller architectural speaker can still be engineered around directivity and headroom.
The P4i sits between the P2i and P6i in the Insight point-source family. Wisdom combines a planar magnetic driver with four 3×5-inch woofers and allows vertical or horizontal installation.
For cinema design, the useful question is whether its output and 60° × 30° nominal coverage suit the actual listening distance and channel role — not simply whether it fits the wall cavity.
SYSTEM ROLE
Where it fits in a cinema.
Surround / wide
A useful architectural channel when more output is required than a compact speaker can comfortably provide.
Height channels
Its in-wall / in-ceiling flexibility can help when the room geometry favours a flush architectural solution.
ROOM DESIGN
The radiation pattern must suit the seats and the architecture.
CoverageUse the nominal 60° × 30° pattern as part of the seat-coverage calculation.
CavityCoordinate wall depth, air volume, structure and grille details before construction.
Bass hand-offTreat the low-frequency system as a separate design layer; this site focuses on the loudspeaker channels.
