Wisdom In Wall Line Source SAGE SERIES L100i
£0.00
The larger in-wall line-source loudspeaker in Wisdom Audio’s Sage Series — a dual planar-magnetic array over eight high-output woofers, engineered to disappear into the wall while filling a large room with even, low-reflection sound.
Description
Description
Overview
The Sage Series L100i is an in-wall line-source loudspeaker from Wisdom Audio, built for listeners who want full-range, reference-grade sound without a visible cabinet. It pairs a tall thin-film planar-magnetic array with a separate high-output woofer section, so the speaker itself effectively vanishes into the wall while still delivering scale and authority across a large room. It is offered as the in-wall L100i, with a matching on-wall L100m for rooms where an in-wall fit is not possible.
Design & build
Both the planar and bass columns are slim architectural sections designed to sit flush in the wall behind a paintable grille, which can be colour-matched to the décor or specified as a custom-length grille to suit the room. Because it is a true line source rather than a boxed speaker, the L100i avoids the bulky enclosure that a conventional full-range design of this capability would demand, and lends itself to open-plan living spaces and dedicated media rooms alike.
Sound & performance
The line-source geometry is central to how the L100i performs: it distributes sound uniformly across the width of a room and substantially reduces floor and ceiling reflections, which keeps clarity and imaging consistent over distance and across a wide seating area. The result is an open, detailed presentation with genuine dynamic headroom, well suited to large modern rooms where a point-source speaker would struggle to stay even from seat to seat.
Key features
The planar array uses two 24-inch thin-film planar-magnetic drivers — a 48-inch driving surface in total — covering six octaves for wide, coherent midrange and treble. Beneath it, eight proprietary high-output woofers handle bass and mid-bass, giving substantial low-end from a slim in-wall footprint. The planar film is a lightweight PEEK material chosen for fast, low-mass acceleration and low distortion.
Technology
Like all Sage Series line sources, the L100i is an actively driven system rather than a passive box. It requires an outboard active crossover with DSP, and three channels of amplification, so the planar and woofer sections are each driven and equalised precisely for the room. This active approach is how Wisdom Audio extracts consistent full-range performance from an enclosure this thin, and it is why professional calibration is part of the install.
Specifications
Type: in-wall line-source loudspeaker (planar-magnetic array plus woofer section). Planar drivers: two 24-inch thin-film planar-magnetic (48-inch total), covering six octaves. Woofers: eight high-output. Frequency response: 40Hz–20kHz ±3dB. Planar impedance: 4.5 ohms resistive; woofer impedance: 4 ohms nominal, 2.5 ohms minimum. Peak power handling: greater than 1000W. Requires outboard active crossover, DSP and three channels of amplification. Finishes: paintable grille, custom colours and custom-length grilles available.
Who it’s for
The L100i suits a large, high-performance two-channel or home-cinema room where the client wants uncompromised, full-range sound but no visible loudspeaker. It is an installer’s speaker in the best sense — specified, positioned and calibrated as part of a considered system rather than bought off the shelf.
Why buy from Hidden Home Technology
Wisdom Audio is sold and installed, not simply shipped: the L100i only performs to its potential when the array, amplification and DSP are matched to the room. We design, fit and calibrate Wisdom systems across the South, and can demonstrate what planar line-source loudspeakers sound like in a properly assembled system.
