A walk-in wardrobe finished in high-gloss, mirror-lacquered walnut is one of the least forgiving surfaces in a house to mount anything on — any visible bracket, grille lip or seam shows up doubled in the reflection. That's exactly the brief XSCACE was given for this dressing room install: sound while getting ready, with zero visual interruption to the lacquer.
Case Study at a Glance
- Room: walk-in wardrobe / dressing room
- Product: Bonsai (12mm slim-array)
- Mounting surface: high-gloss lacquered walnut doors
- Finish: champagne aluminium
- Goal: zero visible hardware on a mirror-finish surface
Sizing the amplifier for a single-zone dressing room
A dressing room zone is typically one or two Bonsai units on a single amplifier channel pair, well within an Air Amp's 80W RMS per channel — so headroom was never the constraint here. The harder engineering problem was mechanical, not electrical: a lacquered door is a moving part (it opens), so the speaker cable run has to account for door swing and hinge clearance, routed through the door's own cavity rather than surface-run, which is part of why the shallow 12mm depth mattered as much for the cable channel as for the visible face.
Why Bonsai
At 12mm deep, Bonsai is the thinnest speaker XSCACE makes — thin enough to sit nearly flush against a lacquered panel door rather than requiring a cavity cut into it, which would have meant compromising the door's structure and finish. The champagne-toned aluminium chassis was chosen to read as an intentional design accent against the walnut rather than trying to hide, which paradoxically makes it less noticeable than a grille forced to match the wood tone.
The engineering trade-off
Bonsai's 300Hz–18kHz range is a deliberate compromise: at 12mm depth, there isn't enclosure volume for real bass extension, so the driver is tuned to do the mid-range and top end extremely well and hand off everything below 300Hz to a separate subwoofer. In a dressing room this is close to ideal — most of what's audible while getting ready is voice, streamed music's vocal and instrumental range, not sub-bass — so the compromise costs almost nothing in daily use.
The system
Bonsai is paired with an Air Amp for wireless streaming directly into the passive driver, and an Acacia 6 Powered subwoofer handles the 35Hz–300Hz band the Bonsai hands off — placed outside the wardrobe itself, in an adjacent cavity, so no low-frequency enclosure has to compete for space with hanging rails and drawers.
Planned, controlled and calibrated for low-level listening
Every XSCACE installation follows the same three stages: planned in the simulator, controlled from the app that matches the hardware, and calibrated with measurement. A bedroom is used quietly, and quiet listening is unforgiving — at low level, timing and tonal balance are all that is left.
Planned
XSCACE Floorplan Sound Simulation takes a plan from trace to bill of quantities in the browser. For a room like this the outputs that matter are:
Coverage at the bed, the one position that matters
Placement checked against soft furnishing, which absorbs unevenly across frequency
Quantities and finishes agreed before joinery is cut
Controlled
Day-to-day control is XSCACE Controller on iOS and Android. It handles volume, EQ and grouping, and the streaming amplifiers also appear natively as AirPlay 2 and Spotify Connect targets, so the app is for control rather than for getting audio into the room.
Calibrated
The calibration toolkit inside XSCACE Studio measures what the room actually does — eleven instruments covering SPL, delay, levels, polarity, frequency response, THD, sub alignment, transfer function, RT60, RTA and export, free on macOS. Here the ones that earn their place are:
Levels matched channel to channel, so the image sits where it should
RT60 to ISO 3382 — soft rooms measure very differently from the rest of a house
Frequency response, because tonal balance is what carries at low volume
Bonsai runs down to 300Hz and Acacia 6 Powered reaches 35Hz, meeting at the 300Hz crossover both records specify — a number to verify by measurement rather than assume.
