Whole-Home Audio Installation in Katy & Houston, TX

Whole-home audio, designed to disappear into your home

Whole-home audio is music that follows you through the house — the same playlist in the kitchen and on the patio, a podcast in the primary bath, the game in the living room and something quieter in the office, each space at its own volume and each controllable from a wall keypad or your phone. EVOTECH IT LLC designs, wires and configures these systems for homes and businesses across the Katy and Houston area, from a two-zone kitchen-and-patio setup to a fifteen-zone new build with speakers in every room.

We are a licensed and insured low-voltage contractor with more than 20 years of hands-on experience and a 5.0-star rating. That experience matters here because whole-home audio is not a product you buy — it is a system you design: the right speakers in the right ceilings, the correct number of amplifier channels, speaker wire run cleanly back to one location, and control that a guest can use without an instruction manual. Get any of those wrong and you end up with rooms that are too loud or too quiet, an app nobody can log into, or a boomy speaker bleeding into the bedroom next door.

The four building blocks

Every whole-home system, whatever the brand, is built from the same four parts: sources — the streaming services, TV and devices the music comes from; zones — the areas you control independently; amplification — what drives the passive in-ceiling and in-wall speakers from a central rack; and control — the app, wall keypads and voice you run it all with. A reliable home network ties them together, which is why we treat your Wi-Fi and cabling as part of the job. The sections below take each part in turn.

This page is a straight, no-jargon guide to how these systems actually work — the two ways to build one, how speakers and zones and amplifiers fit together, the wiring behind the walls, what our installation includes, and the honest choices that drive both sound quality and cost. It is different on purpose from a single-room job like soundbar mounting or a dedicated home theater: whole-home audio is about many rooms working as one system, not one room done well.

Two ways to build it: streaming nodes vs. a central matrix

There are two proven architectures for whole-home audio, and choosing the right one for your house is the biggest decision we help you make. Both can sound excellent; they differ in flexibility, wiring and cost.

Streaming-node systems (Sonos and similar)

Here each zone gets its own small streaming amplifier — a Sonos Amp or an equivalent — that pulls music from the network and drives that room’s in-ceiling speakers. Zones talk to each other wirelessly and stay perfectly in sync, so you can group the whole downstairs with a tap. It is the easiest system to expand one room at a time, and the app is polished. The trade-off is a powered device per zone and reliance on a single company’s ecosystem.

Centralized matrix systems

Here every speaker pair is home-run back to one rack that holds a multi-zone amplifier or an audio matrix switcher. Any source can be routed to any zone, in-wall keypads give physical control in every room, and there is no powered box hidden above each ceiling. This is the classic choice for large or new-construction homes where you want everything centralized, serviceable and controlled from the wall as easily as from a phone. It takes more wire and more up-front planning.

Hybrid systems

In practice we often blend the two — a matrix or multi-zone amp for the bulk of the house with a streaming node feeding it, so you get centralized wiring and keypads plus the convenience of app-based streaming and grouping. The right mix depends on your home and how you listen.

Neither is universally better. We recommend based on your house, whether you are pre-wiring or retrofitting, and how much you value wall control versus app-first simplicity.

In-ceiling, in-wall and outdoor speakers — which goes where

The speaker is where the system meets the room, and picking the right type for each space is most of what makes a house sound good rather than merely loud. Here is what we install and where each earns its place.

In-ceiling speakers

The workhorse of whole-home audio. A round grille sits flush with the ceiling and all but disappears, spreading sound evenly downward — ideal for kitchens, hallways, bathrooms, offices and open-plan living where you want music present but the source invisible. A pivoting tweeter lets us aim the high frequencies toward the seating rather than straight at the floor. For true stereo we install a pair; for a large open space we install several to keep volume even from corner to corner.

In-wall speakers

Rectangular speakers that mount in the wall, better suited to rooms where you sit facing one direction and want proper left-right stereo imaging — a media wall, a bonus room, or a family room where the audio should come from ear level rather than overhead. They are also the natural front speakers when whole-home audio meets a TV in the same room.

Outdoor and moisture-rated speakers

The patio, pool deck and outdoor kitchen are just another zone — but they need weatherproof speakers built for Gulf-coast humidity, sun and rain, whether flush-mounted under a soffit or hidden as landscape and rock speakers in the beds. Bathrooms and covered patios likewise call for moisture-rated in-ceiling models. We cover the yard and patio in depth on our outdoor speaker installation page, and we tie those zones into the same whole-home system.

Subwoofers

In-ceiling and in-wall speakers are easy to hide but light on bass. Where you want fuller sound — a great room, a home gym, an entertaining space — we add an in-wall or hidden powered subwoofer so the low end is felt, not missing.

We also fit the right back-box or baffle behind flush speakers where it matters — it controls the sound, meets fire-rating requirements in some ceilings, and keeps audio from bleeding into the room above or the bedroom next door.

Audio zones: designing around how you actually live

A zone is an independently controlled area, and thoughtful zoning is what makes a whole-home system feel effortless instead of fiddly. The goal is that every part of the house you use differently can be controlled differently — without over-building rooms you would always run together.

How we plan zones

We walk the house and ask how you live in it. The kitchen and open living area are often one zone because you use them together; the primary suite and its bath are usually their own zone so late nights and early mornings do not wake anyone; the patio and pool are a zone that runs when the family is outside; the office, gym and guest room each tend to want independent control. A typical home lands between four and eight zones, though large or new-construction homes can justify more.

Stereo pairs vs. single speakers per zone

Small rooms — a bath, a laundry, a walk-in closet — are fine with a single speaker playing both channels. Living spaces deserve a proper stereo pair so the sound has width and does not collapse into one point. Big open areas need several speakers wired so the whole zone stays at an even volume rather than being loud under one speaker and faint across the room. We size each zone to the space.

Grouping and following you

Zones are not just separate — they can be linked. Group the whole downstairs and the patio for a party so everything plays in sync, then split them back apart afterward. On streaming-node systems this grouping is a single tap; on a matrix we set it up on your keypads and app so it is just as easy.

Streaming platforms: Sonos, AirPlay and the services you’ll use

The platform is the software brain of the system — how music gets from the internet to your speakers and how you pick and sync it across rooms. Getting this right is what makes the whole thing pleasant to use every day.

Sonos and similar ecosystems

Sonos is the best-known whole-home streaming platform, and for good reason: one app searches your services, plays to any room or group of rooms, keeps everything in sync, and adds rooms cleanly over time. It is our common recommendation, but it is not the only good option — several comparable platforms do the same job, and we match the platform to your speakers, your budget and the ecosystem you already use.

The services that play through it

Whatever platform you choose, your existing subscriptions play through it — Spotify, Apple Music, Amazon Music, Pandora, Tidal, internet radio, podcasts and audiobooks. You are not locked into one music service; the platform is the plumbing, and you keep listening to whatever you already pay for.

AirPlay 2 — the platform-agnostic path

Apple’s AirPlay 2 lets an iPhone, iPad or Mac stream to compatible speakers and amplifiers in multiple rooms at once, independent of any single brand’s app. For Apple households it is a flexible, familiar way to run the house, and we frequently combine it with a streaming platform so you have both.

Why the network matters

All of this rides on your Wi-Fi and wiring. Multiple rooms streaming lossless audio at once will expose a weak network fast — dropouts, rooms falling out of sync, a spinning app. We wire streaming devices to the network where we can and make sure your Wi-Fi coverage and network cabling can carry the load before we ever hang a speaker.

Amplifiers, matrix switchers and the equipment rack

Passive in-ceiling and in-wall speakers need something to drive them, and how that amplification is organized is what separates a tidy, serviceable system from a closet full of mystery boxes.

Multi-zone amplifiers

A multi-zone amplifier drives several zones from one chassis — commonly six, eight or more — with enough clean power per channel to match your speakers so nothing distorts at volume. Matching amplifier power to speaker sensitivity and impedance is a real engineering step, not a guess; under-power a good speaker and it sounds thin, over-drive a small one and you damage it.

Audio matrix switchers

A matrix is a switchboard for sound: it lets any input reach any zone, so the turntable can play in the office while streaming fills the rest of the house. Matrix systems are the backbone of larger installs and any job where you want true any-source-to-any-room routing from a central rack.

The equipment rack or structured-media enclosure

Everything central lives in one place — a rack in a closet, garage or utility room, or a structured-media enclosure. We power it cleanly, protect it with surge protection, keep it cool and ventilated, and label every cable so the system can be serviced or expanded years later without guesswork. A tidy rack is not vanity; it is what makes the difference the first time something needs attention.

Constant-voltage (70V) systems

When a space needs many speakers on a single run — a large patio, a shop, a restaurant — we may use a 70-volt constant-voltage design instead of standard low-impedance wiring. It lets one amplifier drive a long chain of speakers at even volume, which is why it dominates commercial audio. We cover where it fits below.

Control: app, in-wall keypads and voice

The best-sounding system in the world is worthless if it is annoying to operate. We set up control so every member of the household — and every guest — can run the house without a lesson.

Phone and tablet apps

The app is command central: browse services, pick a room or a group, set volume, save favorites. We install it on your devices, log into your services, name every zone in plain language, and test it before we leave so “Kitchen” really is the kitchen.

In-wall keypads

A phone is not always in hand, and guests do not have your app. A simple keypad by the door lets anyone turn a room on, change the source and set the volume with a button press. For many families the keypad is the control they actually use day to day, and we place one in every zone that benefits.

Voice control

Where you want it, we tie the system to Alexa, Google Assistant or Siri so you can start music hands-free while cooking or getting ready. Voice is a convenience layer on top of the app and keypads, not a replacement for them.

Smart-home integration

Audio rarely lives alone. We can fold it into a broader smart home so a single scene dims the lights and starts the patio music for an evening outside, or so the house goes quiet when you arm the alarm and leave.

The wiring behind it: speaker cable, home-runs and pre-wire

Whole-home audio is, at heart, a wiring job — and the wire is the part you can never see but always live with. This is where cutting corners quietly ruins a system, and where doing it right pays off for decades.

Speaker wire, gauge and rating

We run properly rated in-wall speaker cable — CL2 or CL3 rated for safe in-wall use — and size the gauge to the run: heavier wire for long pulls to the far patio so the signal does not weaken, standard gauge for short runs. Bargain cable and undersized gauge are a common reason distant zones sound weak or dull, and it is invisible until the walls are closed.

Home-runs to one location

Wherever practical we home-run each zone — a dedicated cable from the rack to that room — rather than daisy-chaining. Home-runs give every zone independent control, make faults easy to isolate, and let the system grow. Keypads get their own control cable, usually Cat5e or Cat6, back to the same rack.

Pre-wire during construction vs. retrofit

If your home is being built or remodeled, this is the moment to pre-wire: with open walls we can put a speaker anywhere and run cable invisibly for a fraction of the later cost. In a finished home we retrofit — fishing wire through attics, walls and soffits, which single-story homes with attic access make far easier than two-story runs down a wall. Either way we conceal cable, patch cleanly, and leave no wire stapled across your brick or trim.

Structured wiring the whole house benefits from

Because we are already in the walls, whole-home audio pairs naturally with structured Cat6 cabling for the network the streaming rides on. Doing both at once is far cheaper than opening the same walls twice.

What an EVOTECH whole-home audio installation includes

“Installation” should mean a complete, tuned, documented system you can use the minute we leave — not speakers dropped in a ceiling. Every EVOTECH whole-home audio project includes:

• On-site design. We walk your home, learn how you live in it, and lay out zones, speaker positions, wiring paths and the equipment location before we quote — so nothing is a surprise.
• Right-sized speakers and amplification. We match speaker type to each room and amplifier power to those speakers, so every zone is even, clean and undistorted at real listening levels.
• Clean, concealed wiring. Rated in-wall speaker cable and control cable, home-run where it counts, fished and hidden through walls, attics and soffits, patched and left tidy.
• Central rack setup. Amplifier or matrix, streaming devices, surge protection and ventilation installed and labeled in one serviceable location.
• Platform and account setup. We configure Sonos or your chosen platform, connect your music services, name every zone clearly, and set up app, keypad and voice control on your devices.
• Tuning and walkthrough. We balance volume across zones, set sensible limits, verify every room and group, then show the whole household how to run it — and leave you labeled documentation.

Our installation process, step by step

1. Free on-site estimate. We visit, listen to how you want to use music, walk the house, and give you a clear written scope and itemized quote — no pressure, no invented numbers.
2. System design. We finalize zones, speaker types and counts, the streaming platform, the amplifier or matrix, and where the rack lives.
3. Wiring and rough-in. On new builds we pre-wire with the walls open; on finished homes we fish and conceal cable, working around your schedule and, for businesses, your hours.
4. Install and configure. Speakers go in, the rack is built, the platform is set up, and keypads and apps are programmed and named.
5. Tune, test and train. We balance every zone, verify grouping and control, and walk the whole household through the system.
6. Local support. We are here in the Katy and Houston area — if you want to add a zone or adjust something later, we are a call away at (832) 359-2425.

Homes vs. businesses: 8-ohm stereo vs. 70-volt distributed

Homes and businesses use the same building blocks but solve different problems, and designing one like the other is a classic mistake.

Homes

Residential whole-home audio is about lifestyle: even, pleasant sound in the spaces you live in, invisible hardware, true stereo in the rooms that deserve it, and control the whole family finds easy. These systems use standard low-impedance (8-ohm) stereo pairs, four to eight zones is typical, and the priorities are fidelity, discretion and simplicity.

Businesses

Restaurants, retail, offices, gyms and clinics have different needs: consistent background music across a large floor, volume that staff can set but customers cannot crank, zoning by area, and often paging mixed in. These usually call for a 70-volt constant-voltage design, where many speakers share one amplified line at even volume — the opposite of a home’s stereo pairs. We frequently integrate audio with paging and PA systems so a manager can make an announcement over the music, and we keep commercial installs clean, code-aware and easy for staff to run.

What affects the cost of a whole-home audio system

Every home and every business is different, so we give real, itemized quotes after a free on-site look rather than a fake “starting at” number. The honest drivers of cost are:

• Number of zones and rooms. More independently controlled areas mean more amplifier channels, more wire and more control — this is the biggest single factor.
• Speakers per zone. A stereo pair costs more than a single speaker, and a large open area may need several speakers to stay even.
• New construction vs. retrofit. Pre-wiring open walls is dramatically cheaper than fishing cable through a finished two-story home, where labor and access drive the price.
• Architecture. Single-story with attic access is easiest; two-story runs, concrete or plaster ceilings, long patio pulls and detached structures add labor.
• Streaming-node vs. matrix. A central matrix with keypads in every room is a different scope than a phased streaming-node build, and we price both honestly.
• Speaker and equipment grade. Better speakers, subwoofers, outdoor and moisture-rated models, and larger racks add capability and cost.

Our estimate is itemized so you can see what each part costs and adjust the scope to your budget — a great two-zone system today, pre-wired to grow later, is a completely valid plan. The on-site estimate fee, when one applies, is credited toward your project. For real numbers, request a free on-site estimate or call (832) 359-2425.

Common mistakes that ruin multi-room audio

Almost every disappointing whole-home audio system fails for one of these reasons. Knowing them helps you judge any installer — including us.

1. Too few speakers for the space. One speaker in a big open room is loud in one spot and faint everywhere else, and a single speaker where a stereo pair belongs sounds flat. We size speaker count to the room.
2. Mismatched amplifier and speakers. Under-powered zones sound thin and strain; over-driven small speakers distort and fail. Matching power to impedance and sensitivity is a design step we do not skip.
3. No back-box where it is needed. Flush speakers without a proper baffle or back-box sound boomy and leak audio into the next room or the floor above. We fit them where the ceiling and layout call for it.
4. Skipping the pre-wire. Not running cable while the walls are open on a build or remodel turns a simple pull into an expensive retrofit later. If walls are ever open, wire for audio.
5. Ignoring the network. Streaming to many rooms over weak Wi-Fi causes dropouts and rooms falling out of sync. We make sure the network can carry the audio before we install it.
6. Mixing incompatible gear. Bolting together devices that were never meant to talk leaves you with zones that will not group or an app that only half-works. We design one coherent system.

Avoid these six and a whole-home audio system is a joy for decades. That is the standard we hold every install to.
