Home Theater Installation in Katy & Houston, TX

Professional home theater installation, engineered for your room

A great home theater is not a pile of components — it is a system tuned to one specific room. EVOTECH IT LLC designs, wires, installs and calibrates complete home theaters across the Katy and Houston area: from a clean 5.1 setup in a living room to a fully treated, tiered Dolby Atmos cinema in a dedicated room with a 130-inch projection screen. The parts matter less than the placement, the wiring and the calibration — and that is exactly the part most people cannot do from a box store.

We are a licensed and insured low-voltage contractor with more than 20 years of hands-on experience and a 5.0-star rating. We run the in-wall speaker cable and HDMI to code, place every speaker at the correct angle and height for your seating, set up the AV receiver and run room correction, and hand you a system where one button dims the lights, drops the screen and starts the movie. Then we teach you how to use it.

Below is a straight, no-hype guide to how home theater actually works — surround formats, the receiver, projector versus TV, speaker placement and acoustics, in-wall wiring, seating and lighting, honest cost drivers and the mistakes that quietly ruin most rooms — so you can make a confident decision whether you hire us or not. If you only want the TV wall and a soundbar, that is a different, simpler job — see our soundbar mounting page. If you want music in every room, that is whole-home audio. This page is about a true immersive theater.

5.1 vs 7.1 vs Dolby Atmos: what the numbers actually mean

Every surround format is written as a set of numbers, and once you can read them the whole system makes sense. The format is bed speakers . subwoofers . height speakers. So 5.1 is five ear-level speakers and one subwoofer; 7.1 adds two more surround speakers behind you; and 5.1.2 or 7.1.4 add overhead height channels for Dolby Atmos and DTS:X. That third number is the whole point of modern immersive sound — it puts a helicopter, rain or a flyover above you, not just around you.

5.1 surround

The foundation: front left, center and right across the screen, two surround speakers beside or just behind the seats, and a subwoofer for bass and effects. For a normal living room this is still a genuinely cinematic step up from a TV or soundbar, and it is the format nearly all streaming and Blu-ray content is mixed for.

7.1 surround

Adds a pair of surround back speakers behind the seating, so sounds pan smoothly from front to rear. It pays off most in a dedicated room or a deep living room where seats sit well in front of the back wall — you need physical space behind you for the extra pair to do anything.

Dolby Atmos and DTS:X (object-based audio)

Atmos and DTS:X stop thinking in fixed channels and instead treat sounds as objects the receiver places in three dimensions, including overhead. In practice that means adding height speakers — ideally in-ceiling, or up-firing modules that bounce sound off a flat ceiling. A 5.1.2 (two heights) is the entry point; 5.1.4 or 7.1.4 (four heights) is the enthusiast sweet spot and what we recommend for most dedicated rooms. The result is a dome of sound rather than a ring.

You do not have to build the biggest layout — you have to build the right one for your room shape, seating and ceiling. We design the layout around where you actually sit, not around a marketing number on a box.

The AV receiver: the brain of the whole theater

The AV receiver (AVR) is the single most important box in the system. It decodes the surround formats, switches your HDMI sources, amplifies the speakers, manages bass between the speakers and the subwoofer, and runs the room correction that makes the whole thing sound right. Get the receiver and its setup wrong and it does not matter how good the speakers are.

Channels must match your layout

A receiver rated for 9.2 channels can drive a 7.1.2 or 5.1.4 system; an 11-channel unit handles 7.1.4. Buy the channel count for the layout you are building plus a little headroom so you can add height speakers later without replacing the receiver.

HDMI 2.1, 4K/8K and eARC

For a system you keep for years, the receiver should pass 4K120 and 8K video, support VRR and ALLM for gaming consoles, and have eARC so a smart TV can send lossless Atmos back to the receiver over one cable. We confirm the exact HDMI spec against your TV, projector and game consoles before anything is purchased.

Room correction is not optional

Every modern AVR ships with automatic room correction — Audyssey (Denon/Marantz), YPAO (Yamaha), MCACC (Pioneer) or premium Dirac Live. It uses a measurement microphone at your seats to measure distances, levels and how your room colors the sound, then applies correction so dialogue is clear and bass is even across the seating. Running this correctly — from the right mic positions, with sensible crossovers — is a big part of what separates a professional install from a DIY one.

When to step up to separates

For large dedicated rooms, demanding tower speakers or the last measure of clean output, we move from an all-in-one receiver to a processor (pre/pro) plus a multichannel power amplifier. It costs more and takes more rack space, but it delivers effortless dynamics and an easy upgrade path. For the majority of homes, a good AVR is the right, honest call — we will tell you which camp your room is in.

Projector or big-screen TV? The honest decision

This is the choice that shapes the whole room, and the honest answer is: it depends on light. A projector gives you a true movie-sized image; a TV gives you brightness and simplicity. We help you pick based on the room you actually have, not the one in the showroom.

Projector + screen

Nothing matches a 100-to-150-inch image for immersion, and a modern laser projector removes the old bulb-replacement headache. The catch is light: projectors look their best in a dark or light-controlled room. In a room with some ambient light, an ambient-light-rejecting (ALR) screen or an ultra-short-throw (UST) laser that sits just below the screen can still look excellent. Throw distance, screen gain, mounting and screen size all have to be planned together — we cover the deep detail on our projector installation page.

Large-format TV (85–98 inch)

If the theater doubles as a bright living room, a big OLED or mini-LED/QLED TV is often the smarter choice. OLED gives perfect blacks and is unbeatable in a darkened room; mini-LED QLED goes far brighter and fights daylight better and, with HDR, makes highlights pop. TVs need no screen, no throw distance and no bulb, and they are simpler to live with.

Our rule of thumb: dedicated or darkenable room, go projector; bright multi-use room, go big TV. We size the image to your seating distance so it fills your field of view without straining your eyes.

Speakers and their jobs: LCR, surrounds, heights and subs

In a surround system every speaker has a specific role, and matching them correctly is what makes sound move seamlessly around the room instead of jumping from box to box.

Left, center, right (the front stage)

The three front speakers do most of the work. The center channel carries the majority of dialogue and is the single most important speaker for intelligibility — never skip or undersize it. The left and right handle music, effects and the width of the front stage. These three should be timbre-matched (same brand and line) so a sound panning across the screen keeps the same tone.

Surrounds

Side and rear surrounds create envelopment and place effects around and behind you. For Atmos, direct-radiating monopole surrounds generally beat the older bipole/dipole style because object audio wants precise placement, not diffuse fill.

Height / Atmos speakers

The overhead layer. In-ceiling speakers aimed at the seats are the best-sounding option and the cleanest visually. Where you cannot cut the ceiling, up-firing modules that reflect sound off a flat 8–10 ft ceiling are a legitimate second choice. We match the approach to your ceiling and budget.

Subwoofer(s)

The subwoofer reproduces the .1 low-frequency effects channel and the bottom octaves of everything else. Sealed subs are tight and accurate; ported subs play louder and deeper. The single biggest upgrade most rooms can make is going from one sub to two — dual subs smooth out the bass so it is even across all the seats instead of booming in one chair and disappearing in the next.

Speaker form factors

• Floorstanding towers — the most output and deepest bass, best for larger dedicated rooms.
• Bookshelf — excellent sound on stands or shelves; pair with a sub for low end.
• In-wall / in-ceiling — nearly invisible, spouse-approved, ideal for living rooms; slightly less bass, so we lean on the subwoofer.
• On-wall — slim boxes that flank a wall-mounted TV where in-wall is not possible.

There is no single best speaker — there is a best mix for your room, your walls and how visible you want them.

Speaker placement and acoustics: where the magic really happens

You can buy world-class speakers and make them sound mediocre by putting them in the wrong place, and you can make modest speakers sound superb by placing and treating them correctly. This is the part DIY installs almost always get wrong, and it is where we spend the most care.

The listening position comes first

We design the whole layout around your main listening position. Left and right form roughly an equilateral triangle with the seats; the center sits directly under or over the screen aimed at ear height; the surrounds go slightly above ear level to the sides and rear at the correct Dolby angles. Seats should not be jammed against the back wall, where bass piles up and the surround field collapses.

Taming room modes (the bass problem)

Every room has room modes — standing waves set by the room dimensions that make bass boom at one spot and vanish at another. We place the subwoofer(s) to minimize this (dual subs in the right spots are the most effective fix), and add bass traps in the corners where low-frequency energy collects.

First reflections

Sound bouncing off the side walls and ceiling between the speaker and your ears smears clarity and imaging. Using the classic mirror trick we find those first-reflection points and treat them with absorption or diffusion so what you hear is the speaker, not the room.

Absorption vs diffusion

The goal is a balanced room, not a dead one. Absorption panels kill harsh reflections; diffusers scatter sound to keep the room lively and spacious. Over-treating makes a room sound unnaturally dead, so we aim for the balance that keeps dialogue crisp and effects enveloping. In a living room we get most of the benefit tastefully — rugs, drapes, upholstered furniture and a few discreet panels — without turning your den into a recording studio.

In-wall wiring and pre-wire done to code

Clean, concealed, correctly rated wiring is the backbone of a home theater and the part you should never see. Running it right the first time is far cheaper than fishing it back through finished walls later.

Speaker cable: rating and gauge

Anything run inside a wall or ceiling must be CL2/CL3 in-wall rated — this is a fire-code requirement, not a preference. We size the gauge to the run: 16 AWG for short runs and 14 or 12 AWG for long runs and low-impedance speakers, so you do not lose power and damping down a long cable.

HDMI over distance

Long HDMI runs to a projector are where cheap cable fails. Past roughly 25 feet we use active fiber-optic HDMI rated for the full 4K/8K bandwidth, and wherever possible we pull it through conduit so the cable can be upgraded when HDMI standards change again — which they will.

Pre-wire vs retrofit

If your room is being built or remodeled, pre-wiring before the drywall goes up is the ideal, lowest-cost path: we place back boxes, run every speaker, HDMI, network and control cable, and leave clean wall plates. In a finished room we retrofit — fishing walls and attics and concealing cable — which takes more labor but still ends up invisible. Either way we coordinate the low-voltage runs with your structured cabling; see our Cat6 cabling and network cabling pages, because streaming 4K HDR and running the control system depend on solid network drops, not just Wi-Fi.

Seating, sightlines, lighting and the room itself

The picture and sound live inside a room, and the room decides how good the experience feels. A few decisions here separate a real theater from a TV with nice speakers.

Seating and sightlines

We plan the screen height and seating distance so the image fills a comfortable field of view and the bottom of the screen is visible from every seat. For a second row we design a riser tall enough that the back row sees over the front row — the classic mistake is a second row staring at the backs of heads. Seat distance is set from the screen size, not from where the outlet happens to be.

Lighting

Light is the enemy of contrast. In a dedicated room we plan blackout shades, dimmable scene lighting, and bias lighting behind the screen that reduces eye strain and makes blacks look deeper. Wall sconces and step lights let people move safely without washing out the picture. This is where a home theater meets home automation — one ‘Watch Movie’ scene can dim the lights, close the shades, drop the screen, power the projector and switch the receiver to the right input. We wire that through our smart home installation service.

The room shell

In a dedicated build we can add acoustic treatment, solid-core doors and even a raised floor for a tactile bass. In a living room we work with what you have and get most of the benefit through smart placement, an ALR screen or bright TV, and tasteful treatment — no demolition required.

What a professional EVOTECH home theater install includes

‘Installation’ should mean a complete, calibrated, documented theater — not speakers leaned against a wall. Every EVOTECH home theater project includes:

• On-site design & acoustic assessment. We measure the room, study your seating, ceiling and light, and lay out speaker positions, the screen or TV size, and cable paths before we quote.
• In-wall / in-ceiling wiring to code. CL-rated speaker cable, fiber HDMI for long runs, network and control cabling, concealed and terminated to clean wall plates.
• Precise mounting and aiming. Screen or TV, projector, and every speaker mounted solidly and aimed at the seats — including in-ceiling Atmos speakers angled correctly.
• Receiver & source setup. We install and configure the AVR or processor, connect and label every source, and set HDMI, eARC and bass management properly.
• Microphone calibration. We run room correction from multiple seat positions and verify levels, distances, crossovers and subwoofer integration by measurement, not by guessing.
• Simple control. One-touch scenes on a universal remote or app so the family can actually use the system without a stack of remotes.
• Walkthrough & support. We show you how everything works, leave it labeled, and are a local phone call away at (832) 359-2425 if anything needs a tweak.

Our home theater installation process, step by step

1. Free on-site estimate. We visit, learn how you want to use the room, measure it, and give you a clear written scope and itemized quote. No pressure and no invented numbers.
2. System design. We finalize the surround layout (5.1, 7.1, Atmos), projector-vs-TV, speaker selection, receiver and control, and confirm seating and screen size with you.
3. Pre-wire / rough-in. We run and conceal all speaker, HDMI, network and control cable and set back boxes and mounts — coordinated with your builder if the room is under construction.
4. Install & connect. Screen or TV, projector, speakers, subwoofer(s), receiver and sources go in, get mounted, aimed and connected.
5. Calibrate & tune. We run measurement-based room correction, set levels and crossovers, align the picture, and dial in the whole system by ear and by meter.
6. Train & support. We program simple scenes, walk you through it, and stay local for adjustments down the road.

Dedicated theater vs living-room media room

A dedicated theater and a living-room system use the same technology to solve different problems, and pretending they are the same is a common and expensive mistake.

Dedicated theater room

A dedicated room gives you total control: full blackout for a big projector, freedom to place surround and Atmos speakers exactly where the layout wants them, acoustic treatment on the walls, tiered seating on a riser, and a single-purpose design nobody has to compromise. It is the path to the best possible result and to a true 7.1.4 or larger Atmos system.

Living-room / media room

Most families want cinema sound and picture in a room that is also for daily life, and that is completely doable — it just changes the choices. Ambient light pushes you toward a bright TV or an ALR/UST projector; aesthetics push toward in-wall and in-ceiling speakers and a hidden subwoofer; and the layout has to respect the furniture and the people who live there. The honest trade is a little ultimate performance for a room you use every day.

We are glad to build either, and we will tell you honestly what your room can and cannot deliver before you spend a dollar.

Designed for Katy & Houston homes

We install throughout Katy, Houston, Sugar Land, Richmond, Fulshear, Cypress and the surrounding communities, and we design for how homes here are actually built. Many local great-rooms have lots of glass and hard afternoon sun — rooms where a projector on a bare wall would disappoint, so we steer those toward a large bright TV or an ambient-light-rejecting screen. New construction and remodels across Katy and Fulshear are the perfect chance to pre-wire for Atmos before the drywall closes, and we coordinate with builders to place back boxes and conduit early. Being local also means service is a short drive away — not a support ticket to another state.

What affects the cost of a home theater installation

Every room and every goal 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:

• Surround layout & channel count. A 5.1 system is far simpler than a 7.1.4 Atmos build with in-ceiling speakers and a bigger receiver.
• Display choice. A projector, screen and their mounting differ in cost from a large TV, and an ALR or UST setup differs again.
• Speaker type & count. In-wall and in-ceiling speakers add labor for cutting and finishing; towers, dual subwoofers and premium lines cost more than a basic package.
• Wiring: pre-wire vs retrofit. Running cable before drywall is cheaper than fishing finished walls; long projector HDMI runs and conduit add materials.
• Room work. Acoustic treatment, blackout shades, tiered seating, a riser and scene lighting are optional layers that add both experience and cost.
• Control & automation. A single universal remote is modest; full lighting, shade and one-touch scene integration adds capability and cost.

Our estimate is itemized so you can see exactly what each part costs and stage the project to your budget — for example, pre-wiring for Atmos now and adding the height speakers later. The on-site estimate fee, when one applies, is credited toward your project. To get real numbers for your room, request a free on-site estimate or call (832) 359-2425.

Six mistakes that ruin a home theater (and how we avoid them)

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

1. Skipping calibration. Speakers left on factory defaults with no room correction sound harsh and uneven. We calibrate every system by measurement, from your actual seats.
2. An undersized or single subwoofer. One weak sub booms in one chair and disappears in the next. We size the sub to the room and use dual subs to even out the bass.
3. Wrong speaker height and angle. Surrounds too low, a center firing at knees, Atmos speakers pointed at a wall — all destroy the effect. We set every angle to the seats.
4. A projector in a bright room. A great projector on a white wall in daylight looks washed out. We match display to light: TV or ALR screen for bright rooms, projection for controlled ones.
5. Mismatched speakers across the front. A center from one brand and towers from another make sound lurch as it pans. We timbre-match the front stage.
6. Cheap or unrated in-wall cable and no plan for HDMI. Non-rated cable is a code problem, and a cheap 40-foot HDMI to the projector fails at 4K. We use rated cable, fiber HDMI and conduit for the future.
