The house as instrument.
In-ceiling, in-wall, and invisible speakers disappear into the architecture. Streaming zones — from kitchen to pool deck — are always on, always in sync, and always at the right volume. No Bluetooth compromises.
Matrix Digital Systems designs high-resolution whole-home audio and dedicated hi-fi listening rooms across Southern California and Central Texas — invisible in-wall, architectural, and outdoor speakers from Sonance, Stealth Acoustics, James Loudspeaker, and Coastal Source, with Roon, Tidal, and Apple Music integration.
Speakers you don't see.
Our architectural audio work uses plaster-in and trim-less speakers from Sonance, Triad, and Monitor Audio — carefully positioned so that music feels as though it's coming from the room, not a box.
Every zone gets a dedicated high-current amplifier — Crestron Audio or Savant Audio at the rack — fed by a high-resolution streamer. The source — Apple Music, Tidal, your own library — is the only thing you think about.
From the kitchen to the pool deck.
We design audio zone by zone, room by room. The kitchen is bright and punchy. The primary suite is warm and quiet. Outside, landscape speakers hidden in planters throw clean sound over a large yard without disturbing neighbors.
Two-channel rooms — for serious listening — get dedicated stereo pairs, a real subwoofer, and a room tuned by ear and measurement.

Can speakers be hidden entirely inside the wall or ceiling?
Yes. Stealth Acoustics and Sonance Invisible Series speakers mount behind drywall and finish flush with the surface — invisible after paint. Sonic performance is competitive with quality in-ceiling speakers when properly specified and treated; not a substitute for a reference theater pair, but ideal for living spaces where the architecture must read first.
How many audio zones do most homes actually need?
More than you'd think. A typical project we install runs 8–14 zones: primary suite, primary bath, kitchen, dining, living, family, office, patio, pool, garage. Each zone gets its own source choice and volume. We size the system after walking the house with you — never from a floor plan alone.
Will outdoor speakers survive Southern California weather and salt air?
Yes, when specified correctly. We install marine-grade outdoor speakers from Sonance, James Loudspeaker, and Origin Acoustics with sealed enclosures and powder-coated grilles. For coastal homes within a few miles of the water, we step up to fully sealed bronze or stainless hardware and budget for a 5–7 year refurb cycle.
What is the difference between a streaming receiver and a proper distributed audio amplifier?
A streaming receiver drives one or two zones from one source. A distributed audio amplifier — Autonomic, Crestron Sonnex, or Savant — drives 8 to 32 zones with independent sources, independent volume, and a single control app. The latter is what makes whole-home audio actually feel like one system.
Can I use my existing music subscriptions — Apple Music, Tidal, Spotify, Qobuz?
All of them. The streaming layer we install supports every major service plus high-resolution playback from Tidal and Qobuz at native bit depth. AirPlay 2 and Roon are first-class citizens. Your existing library and subscriptions come with you.
Why does the same speaker sound different in different rooms?
Because the room is the speaker, eventually. Bass reinforcement, first reflections, ceiling height, and absorption all reshape what reaches your ears. We calibrate each zone with measurement microphones and room correction (Dirac or Sonance Sub Control) so two rooms running the same album actually sound like they're playing the same album.
Do you build dedicated hi-fi listening rooms?
Yes. For serious audiophiles we design two-channel listening rooms with acoustic treatment, dedicated power, isolation platforms, and high-end electronics from McIntosh, Naim, Meridian, Focal, Bowers & Wilkins, KEF, and Rotel. The room itself is engineered as carefully as the electronics.
Can outdoor audio survive Central Texas summers?
Yes. For Hill Country and Lake Austin installs we specify weather-tuned outdoor speakers rated for the temperature swings and UV, with cabinet-grade materials designed to hold up in triple-digit heat. Pool and dock installs get marine-grade hardware.
Do you calibrate the sound in every zone?
Yes. Every zone is measured and tuned. Listening rooms get full room-mode analysis and correction. Outdoor zones get weather-tuned crossovers so treble doesn't disappear on windy patios.
Do you build ranch-scale distributed audio?
Yes. Central Texas ranch installs commonly need audio distribution across a main house, guest house, barn, and outdoor entertaining areas — sometimes 20+ zones. We handle the fiber runs, distributed amplification, and RF-hardened control.
Do you work with Trinnov audio processors?
Yes. Trinnov Altitude processors and their measurement tools show up in most of our reference-tier theater and hi-fi listening rooms. Room-correction that actually respects the music.
Can I add a dedicated listening room to an existing house?
Yes. A dedicated two-channel room is one of the highest-value retrofits available. We can convert a den, office, or under-used bedroom into a real listening room in 30-45 days with acoustic treatment and dedicated power.
