Case Study: Cedar in a Marble, Hotel-Style Reception Lounge

How a hotel-grade reception lounge got higher-output sound on book-matched marble — XSCACE Cedar chosen for its 96dB sensitivity in a room built for a crowd, not a single seat.

XSCACE Cedar speaker mounted on book-matched grey marble in a formal reception lounge

A formal reception lounge with floor-to-ceiling glass, book-matched grey-veined marble, and hotel-lobby-grade furnishing needed a speaker built for a room that regularly holds more people than a private living room — sound that stays clean and controlled across a crowd, not just at one seat. Cedar was specified here instead of the thinner Cane or Bonsai, mounted on a dark grey marble panel beside ribbed bronze wood-slat cladding.

Case Study at a Glance

  • Room: formal reception lounge, hotel-lobby scale
  • Product: Cedar (74.9mm, 100W RMS, 96dB)
  • Mounting surface: dark grey book-matched marble + bronze wood-slat cladding
  • Finish: black aluminium
  • Goal: higher-output coverage for a larger, higher-traffic space

When a room outgrows the thinnest options

Not every room should default to the thinnest possible speaker — a large reception lounge with hard marble and glass surfaces benefits from the additional headroom a deeper enclosure like Cedar provides, because harder surfaces reflect more sound energy and a system pushed near its limit in that environment sounds strained well before a system with more reserve capacity does. The 62.9mm of extra depth over Cane bought meaningful acoustic capability that mattered more here than the last few millimetres of visual disappearance would have.

Why Cedar over a thinner speaker

Cedar trades depth for output: at 74.9mm, it's considerably deeper than Cane's 23mm or Bonsai's 12mm, but that extra enclosure volume delivers 100W RMS and 96dB sensitivity against Cane's 50W/92dB — meaningfully more headroom for a larger reception space with harder, more reflective marble and glass surfaces that can otherwise make a room sound bright and fatiguing at volume.

4Ω impedance and amplifier sizing

Cedar runs at 4Ω impedance rather than the 8Ω common across XSCACE's thinner models, which changes the amplifier math — a 4Ω load draws roughly double the current of an equivalent 8Ω load at the same voltage, so the amplifier driving it needs to be rated for 4Ω operation specifically, not just have spare wattage in reserve.

The system

A Lucifer 4 four-channel amplifier (250W RMS per channel into 8Ω, correspondingly higher into 4Ω) drives the Cedar array, with a Juniper subwoofer (350W RMS, 25Hz–200Hz) extending low-frequency response across the reception space.

How this room was planned, controlled and calibrated

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 commercial room is judged on consistency — the table by the window should hear what the table by the bar hears.

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 checked table by table, so no seat is the bad seat

Room modes located before the fit-out covers the structure

A bill of quantities the operator can price against

Trace, place, predict — before anything is ordered

Controlled

The amplifier is configured and controlled from XSCACE Studio on macOS — routing matrix, per-channel gain and delay, parametric EQ, crossovers and limiting, with network-wide discovery rather than one amplifier at a time.

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:

RTA noise rating, NC-15 to NC-65, setting the level the system must clear once the room is full

SPL measured at each zone against the design target

RT60 to ISO 3382, showing whether hard surfaces need treating as well as covering

Cedar runs down to 100Hz against Juniper's 25Hz, and the two records recommend different crossover points (100Hz and 200Hz). Which suits the room is a measurement, not a preference.

Frequently Asked Questions
Why choose Cedar over a thinner speaker like Cane or Bonsai?

Cedar trades additional depth (74.9mm) for significantly more output — 100W RMS and 96dB sensitivity — making it a better fit for larger or higher-traffic spaces like reception lounges than thinner, lower-power models.

What impedance does Cedar run at?

Cedar runs at 4Ω impedance, which requires an amplifier rated for 4Ω loads rather than 8Ω-only amplifiers.

Does a 4Ω speaker need a different amplifier than an 8Ω one?

Yes — a 4Ω load draws roughly double the current of an 8Ω load at the same voltage, so the driving amplifier needs to be specifically rated for 4Ω operation, not just have extra wattage headroom.

What subwoofer pairs with Cedar?

The Juniper (350W RMS, 25Hz–200Hz) is a common pairing for larger Cedar installations needing extended low-frequency reach.

Is Cedar suitable for commercial or hospitality-grade spaces?

Yes — Cedar's higher power handling and sensitivity make it well suited to larger, higher-traffic spaces like hotel lobbies, reception lounges, and other hospitality environments.

Is a thinner speaker always the better choice for a high-end room?

Not necessarily — larger or more acoustically demanding rooms, especially those with hard reflective surfaces like marble and glass, often benefit more from a higher-output, moderately deeper speaker like Cedar than from prioritising minimum depth alone.
