Multi-Room Audio — zone graph
- Lounge: Coaxial in-ceiling pair (KEF). Stereo + spoken word. Tweeter on the woofer axis, so the image holds off-centre across an open plan. Product class only — no model is named for this zone.
- Home Theatre: Glass-cabinet floorstanders + in-ceiling height layer (Waterfall Audio). 7.1.4 Atmos cinema. A cabinet meant to be seen, with the height channels hidden in the slab. Product class only — no model is named for this zone.
- Kitchen + Dining: Sonance Visual Performance VP66R (Sonance). BGM during prep + service. Flush low-bezel ceiling grille that stays even off-axis at low volume. Secondary source — Sonance VP Medium Round & Square spec table, retrieved 2026-07-07 (https://dmg-mg.com/sonance/visual-performance/vp-medium-round-square-speakers/).
- Study: Compact bookshelf pair on a streaming pre-amplifier (Polk Audio). Calls + focused listening. Near-field listening at low volume, with the source on the network rather than the desk. Product class only — no model is named for this zone.

What four-zone audio actually asks of the building.
The explorer shows the room-by-room decision 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 flush low-bezel grille — a Sonance Visual Performance VP66R is the worked example in the explorer, cited from the speaker catalogue — is a different specification from a lounge ceiling carrying a coaxial in-ceiling pair: 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, and that asymmetry is the reason we separate the speaker decision from the head-end decision. A passive in-ceiling or bookshelf speaker is a mechanical device on a fixed cable, so a later replacement is a mechanical fit question — backbox, cut-out, impedance — not a firmware question. Streaming endpoints and control ecosystems turn over far faster and carry the compatibility risk. We do not publish a compatibility claim between a specific model and a future one; that is a question for the manufacturer at the time of replacement.

How to read this tool’s output
Stage 1 (brief) or stage 3 (design). Use to align owner expectations on per-room speaker matching before committing to a head-end ecosystem.
What an engineer should know
The assumptions behind the numbers this tool produces.
- Reference four-zone home — Lounge, Home Theatre, Kitchen, Study — each matched to the loudspeaker class the room calls for: a flush low-bezel ceiling grille in the kitchen, a coaxial in-ceiling pair in the lounge, glass-cabinet floorstanders plus an in-ceiling height layer in the cinema, a compact bookshelf pair on a streaming pre-amplifier in the study.
When this tool is the right one
The project moments and room types this is built for.
- Residential whole-home audio briefing conversation.
- Boutique hospitality multi-zone audio scoping.
What changes the answer in practice
Field conditions that move the result away from the planning figure.
- In-ceiling speakers are a structural decision. Backbox depth, joist alignment, AC ducting and recessed lighting all coordinate at false-ceiling planning, not after gypsum closure.
- Network architecture (multicast, VLAN segmentation, AP density) is part of the audio brief — whole-home audio shares the building's data layer.
Defensible starting architectures
Vendor-neutral reference points, not a recommendation to buy — the right answer is the one that survives your site survey.
- Per-room speaker selection led by room use — invisible-grille ceilings for kitchens, coaxial in-ceilings for lounges, glass-cabinet floorstanders for cinemas, compact bookshelves for studies.
Common mistakes
Failure patterns we see on real projects.
- Specifying the same speaker across every room — a kitchen and a lounge ask for different off-axis behaviour, different bass extension and different grille discipline.
- Deciding the head-end (Roon, Sonos, Crestron, Yamaha MusicCast) after the speakers — the ecosystem choice constrains the matrix and the network plan, so it leads.
What this tool does not do
Deliberate limits — where the estimate stops and design begins.
- Streaming-source resilience matters — specify a redundancy chain (NAS + AirPlay + Bluetooth fallback) on contract.
Where this tool fits
The building types this output is calibrated for — and, where we have said so, the ones it is not.
Best suited for
· Why it matters
A whole-home audio plan is not a speaker list — it is a per-room engineering decision. The kitchen needs a flush low-bezel ceiling grille that plays at 35% volume during prep and stays even off-axis across the open plan. The lounge ceiling needs a coaxial in-ceiling pair, because the room is the social heart and the image has to hold off-centre. The cinema needs glass-cabinet floorstanders plus an in-ceiling height layer, because the cabinet is part of the room as well as the soundtrack. The study needs a compact bookshelf pair on a streaming pre-amplifier, because focused near-field listening calls for a different speaker grammar entirely. The class comes from the room; the model comes from the catalogue, with its source, once the room survey is done.
· Frequently asked
Whole-home audio —
what people ask first.
Is this a real installation?
No — the four-room reference is a synthesis of plans the studio specifies regularly across residences and boutique hospitality, not a photograph of one house. Each zone states the loudspeaker CLASS the room's job calls for. Only one zone names a specific model, and it names it because the speaker catalogue carries that record with a source and a retrieval date; the other three name a class and stop there, because no catalogue record stands behind a specific model for them yet.
Why a different speaker in each room?
Because the rooms are doing different jobs. A kitchen at 35% volume during a dinner party rewards a flush low-bezel ceiling grille with even off-axis behaviour and bass that does not boom into the open plan. A lounge ceiling rewards a coaxial in-ceiling pair, where the tweeter sits on the woofer axis so the image holds off-centre. A cinema rewards floorstanders that participate visually as well as acoustically, with the height layer hidden in the slab. A study rewards a compact bookshelf pair on a streaming pre-amplifier. Same-speaker-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.
How is a whole-home audio system specified per room?
In two passes. The first pass fixes the CLASS per room from the job the room does — ceiling-flush for the lounge, flush low-bezel ceiling for the kitchen, visible floorstander plus an in-ceiling height layer for the cinema, compact bookshelf on a streaming pre-amplifier for the study. The second pass fixes the MODEL, and only from records we can cite: the explorer names a Sonance Visual Performance VP66R for the kitchen because the speaker catalogue carries that record with its source, and deliberately names no model for the other three. Exact specification follows a written estimate after review, because it depends on cable runs, in-ceiling backbox availability and the chosen head-end.
