Wisdom In Wall Point Source INSIGHT SERIES P4i
POA
A planar-magnetic point-source loudspeaker that installs flush into the wall, the Wisdom Insight Series P4i pairs a thin-film driver with four woofers for high-resolution, full-bandwidth sound from an invisible enclosure.

Description
Overview
The Insight Series P4i is an in-wall point-source loudspeaker from Wisdom Audio, a specialist in planar-magnetic architectural speakers. It combines Wisdom’s thin-film planar driver with multiple woofers to deliver high-resolution, full-bandwidth sound that disappears into the wall — suited to both serious two-channel music and home cinema.
Design & build
The P4i is designed to install flush into the wall (or ceiling) and be finished to disappear behind a grille, with the option of custom-length grilles to suit the room. It can be mounted vertically or horizontally, and measures 31.61 × 5.52 × 3.43 inches (H × W × D), keeping intrusion into the wall cavity to a minimum.
Sound & performance
The P4i combines a planar-magnetic thin-film driver with four 3 × 5-inch woofers for low distortion and wide dynamic range. Quoted frequency response is 80Hz–20kHz, with 6-ohm impedance, 86dB sensitivity (2.83V/1m) and a maximum output of 109dB at one metre — a clean, detailed and dynamic performance from a flush-mounted enclosure.
Key features
The thin-film planar driver is the heart of the design: an ultra-light membrane that responds instantly to fine detail and has far less inertia than a conventional cone or dome. Four woofers handle the lower registers, and the P4i uses an internal passive crossover (crossover frequency 650Hz), requiring one channel of amplification per speaker.
Technology
Planar-magnetic thin-film drivers move air with a large, light diaphragm rather than a small piston, which Wisdom cites for exceptional clarity and freedom from the blurring associated with heavier drivers. Their large radiating area also lends an effortless, open quality that suits both full-range music and the demands of a cinema soundtrack.

Who it’s for
The P4i suits the client who wants genuine high-end sound without visible loudspeakers — in a music room, media room or dedicated cinema where the speakers must be hidden in the wall but the performance must not be compromised.
Why buy from Hidden Home Technology
Architectural loudspeakers of this class are only as good as their installation and calibration. We design, install and tune Wisdom in-wall systems as part of the room, coordinating with construction and integrating amplification and control.

The Hidden Home view
We have fitted the P4i as the side and surround speaker in two of our cinemas. In an award-winning room in Bath it partners Wisdom’s Sage Line 2 front speakers, and in a north London living room the P4i surrounds were custom painted to match the walls because the client did not want to know the cinema was there.
It is a compact model in Wisdom’s Insight Series, with a planar magnetic driver and four small woofers in a slim frame that goes into a wall or a ceiling. Its response starts at 80 Hz, so in a cinema the subwoofers do the bass. So it suits a cinema or media room where the speakers have to disappear. Wisdom speakers are designed into a room and installed, so call us and we will design the system around yours.
