WHY IT EXISTS
A reference front channel that disappears into a four-inch wall depth.
S7i-LR adapts the S7t architecture to an in-wall format using an integral aluminium rear enclosure and PERLISTEN’s DPC array.
For a cinema, the interesting combination is output plus directivity control: the product can be hidden while still being designed around a predictable radiation pattern.
SYSTEM ROLE
Where it fits in a cinema.
Media rooms
Can also serve as architectural L/R outside a dedicated cinema.
Large rooms
THX Dominus certification positions it for substantial room volumes.
ROOM DESIGN
Choose the room conditions before choosing the quantity.
Wall depthThe shallow enclosure still needs a precisely coordinated cut-out and framing zone.
AmplificationThe 4-ohm nominal load and high output capability deserve serious amplification.
CoverageUse the DPC radiation pattern to determine height and toe orientation.
