Multiroom Audio Perth

The most useful hour in a multiroom audio project is the one spent deciding what counts as a zone. A zone is anywhere someone wants independent control of volume and source. An open-plan kitchen-living-dining is usually one zone despite being three rooms, because nobody stands in the kitchen wanting different music to the person on the couch six metres away.

A typical four-bedroom Perth family home lands on four to six zones: the open-plan living area, the alfresco, the main bedroom, the master ensuite or bathroom, and often a study or gym. Adding kids' bedrooms sounds generous at quoting stage and is almost never used, so we'd rather run the cable and leave the ceiling positions capped for later than sell hardware that sits idle.

Zone count drives everything downstream: amplifier channels, rack size, switchboard capacity and cost. Going from four zones to eight roughly doubles the amplifier spend, so it's worth being honest early about which rooms will genuinely get used.

• 01Open-plan living, kitchen and dining - one zone, two to four ceiling speakers
• 02Alfresco or pool - its own zone on outdoor-rated speakers
• 03Main bedroom and ensuite - one zone, low-level background listening
• 04Study, gym or home office - one zone, often a stereo pair rather than ceiling
• 05Theatre - separate system, integrated for whole-of-house announcements only

Ceiling speaker placement is decided by where people sit, not by where the ceiling grid looks tidy. A pair placed symmetrically in the middle of a room looks neat on a plan and puts both speakers behind the couch in practice. We mark positions on site with the furniture layout in front of us.

Perth ceiling construction limits some of this. Standard timber-truss ceilings give us the roof space to run cable anywhere. Concrete slab ceilings in apartments and some second storeys mean speakers can only go where a bulkhead or ceiling drop exists. Insulation batts need a back-box over the speaker to stop them sitting against the driver.

Speaker choice matters as much as placement. A moisture-rated speaker in the bathroom, a wider-dispersion driver in the kitchen where people move around, and a proper stereo pair rather than two mono points anywhere people sit down to listen properly.

There are two ways to build multiroom audio and they suit different houses. A wired matrix amplifier lives in the rack, runs speaker cable to every zone, and switches sources internally. It doesn't care about WiFi, it's the cheapest way to do eight or more zones, and it pairs naturally with in-wall keypads for people who don't want to use a phone.

A networked system - Sonos, Bluesound, HEOS or a Crestron or Control4 audio system - puts a streaming endpoint at each zone and controls everything from an app. It's more flexible with sources, easier to add a zone to later, and depends entirely on the quality of the home network.

We install both and the recommendation follows the brief. Big house, lots of zones, keypad control, budget-conscious: matrix. Four to six zones, streaming-first household, want it working next week: networked. Mixed households often end up with a matrix backbone and a couple of streaming endpoints feeding into it.

Multiroom audio is a cabling job with speakers attached. We run 14 or 16 AWG oxygen-free speaker cable to every position, a Cat6 to each keypad and each streaming endpoint, and generous spare capacity to the rack because the second phase of an audio system is always more zones.

The rack location gets decided early. Amplifiers generate heat, so a sealed cupboard under the stairs is a slow way to kill hardware. We want ventilation, a dedicated circuit, and enough depth for the amp plus patching. In most homes that's the garage, the laundry, or a purpose-built comms cupboard.

Everything gets labelled at both ends and tested before sign-off, and the as-built pack records which cable feeds which ceiling position. Ten years later when someone wants to change a speaker, that document is the difference between a one-hour job and a day of guessing.
