Four rooms, four speakers, one decision.
Sonance disappears behind plaster in the kitchen. KEF Reference lives flush in the lounge ceiling. Waterfall's glass cabinets sit in the theatre. Polk Reserve handles the study.

What four-zone audio actually asks of the building.
The explorer shows brand-per-room as the headline; the engineering layers underneath are network architecture, speaker placement against the structural slab, source-of-truth control and a service path for the next decade.
Deployment observations
- Speaker selection is room-led, not catalogue-led. A kitchen ceiling carrying a Sonance Visual Performance VP66R is a different specification from a lounge ceiling carrying a KEF Ci-R Reference: bass extension expectations, off-axis behaviour, grille discipline and intelligibility at 35% volume all differ. Specifying both rooms with the same speaker is a budget decision, not an engineering decision.
- Whole-home audio is a network-architecture problem before it is a speaker problem. Roon, Sonos, Yamaha MusicCast, Crestron-distributed audio and KNX-tied audio matrices each commit the house to a different long-term ecosystem. Decide the head-end first; pick the per-room speakers second; ratify the network plan (multicast handling, VLAN segmentation, AP density) third.
- Ceiling-flush in-ceiling speakers are a structural decision, not a finishing decision. Backbox depth, joist alignment, AC ducting and recessed lighting all need to be coordinated at the false-ceiling planning stage — retrofitting in-ceilings after gypsum closure means cutting and re-skimming around finished joinery. The earlier in the project the speaker selection is locked, the cleaner the install.
Operational notes
- Family-led tuning is the first 90 days. The owner discovers what the rooms actually do — dinner-party kitchen at 40% volume, study calls at 18%, theatre nights at reference SPL — and the EQ presets evolve. Budget one tuning visit in the first quarter; this is operational discipline, not warranty work.
- Streaming-source resilience matters. Tidal, Spotify, Apple Music and Roon each go down occasionally; a redundancy plan (local NAS + AirPlay 2 + Bluetooth fallback) means the kitchen still has music when the Tidal CDN has a bad afternoon. Specify the fallback chain on contract.
Lifecycle implications
- Speaker refresh cycles are long — quality in-ceilings and bookshelves run 15-20 years if the room is climate-controlled. The audio matrix (Crestron / Yamaha / NAD) sits at 8-12 years; the streaming endpoints (Roon Nucleus, AirPlay receivers) refresh on a 4-6 year cadence. Plan the cabling for the longest-lived layer — speaker runs to in-ceiling boxes — first.
- Brand longevity is asymmetric. KEF, Sonance, Polk and Waterfall have been making the same product families for 15-25 years; a 2025 KEF Ci-R Reference is firmware-compatible with a 2040 KEF in-ceiling refresh because the architecture is mechanical. Streaming-ecosystem brands turn over faster; this is why we separate the speaker decision from the head-end decision.
· Why it matters
A whole-home audio plan is not a speaker list — it is a per-room engineering decision. The kitchen needs invisible Sonance ceilings that play at 35% volume during prep without a single grille visible across the open plan. The lounge ceiling needs KEF Reference because the room is the social heart. The cinema needs Waterfall Niagara III glass-cabinet floorstanders because the visual is part of the listening experience. The study needs Polk Reserve on a Yamaha streaming pre because focused listening calls for a different speaker grammar entirely.

· Frequently asked
Whole-home audio —
what people ask first.
Is this a real installation?
The four-room reference is a synthesis of plans the studio specifies regularly across residences and boutique hospitality. The speaker pairings (Sonance kitchen, KEF lounge, Waterfall theatre, Polk study) are the practice's defaults for a reference whole-home audio brief.
Why a different speaker brand in each room?
Because the rooms are doing different jobs. A kitchen at 35% volume during a dinner party rewards an invisible-grille Sonance with even off-axis behaviour. A lounge ceiling rewards a Uni-Q coaxial Reference that images well off the slab. A cinema rewards Waterfall's glass-cabinet floorstanders that participate visually as well as acoustically. A study rewards Polk Reserve compactness on a Yamaha streaming pre. Same-brand-everywhere is a budget decision, not a design decision.
Sonos vs Roon vs Crestron vs Yamaha MusicCast — what should we use?
Different ecosystems for different operations. Sonos is the easiest path if the family wants a phone-driven simple multi-room. Roon is the audiophile choice and the head-end we recommend for serious listeners. Crestron-distributed audio is the right call if the house is already on a Crestron control backbone. Yamaha MusicCast slots in if the cinema receiver and audio matrix come from the same brand. The decision is operational, not technical.
Can we add rooms later?
Yes, if the cabling backbone was provisioned at first-fix. The expensive cost of adding a zone after handover is the structural cost — running speaker cable through a finished ceiling. The audio matrix and speaker cost are modest in comparison. We routinely provision four zones at first-fix even when only two are activated at handover.
What is the realistic per-room cost band?
Cost bands sit in three tiers per room. Lounge KEF Ci-R Reference: premium ceiling-flush. Kitchen Sonance VP66R: premium invisible ceiling. Cinema Waterfall Niagara III plus subs: reference-grade visible floorstander. Study Polk Reserve R200 on Yamaha streaming pre: compact reference. Exact figures live in a written quote because they depend on cable runs, in-ceiling backbox availability and the chosen head-end.
