This room didn't used to feel like this. 🎬

One conversation with Corby changed everything.

Custom seating. Calibrated projection. Sound that wraps around you.

Tailored to the way this family actually watches.

Your space could feel like this too.

An AI tool can show you a nice rendering. We can show you the real thing.

We have been designing and installing custom home theaters in North Texas for nearly 30 years. Every detail is planned for how you actually live in the space — the acoustics, the lighting, the sightlines, even where every wire disappears to.

No guesswork. No surprises. Just a system that works exactly the way it should, every time.

Your backyard should sound as good as it looks. 🎶

We recently wrapped up an outdoor audio installation for a North Texas family who wanted music by the pool without sacrificing the look of their space.

The result? Weather-resistant speakers mounted discreetly on the fence, paired with string lights for ambiance, and a system they control right from their phone. No visible wires. No clutter. Just seamless sound that fills the whole backyard.

This is what "tailored to your lifestyle" looks like when it meets the outdoors.

Here's the truth most people get wrong about smart homes: it's not about how many devices you have. It's about how well they work together. 💡

We've walked into plenty of homes where someone bought great gear — a nice receiver, quality speakers, a smart thermostat, outdoor audio — but it's all running on separate apps, separate remotes, and separate logic. The result? A system that's supposed to make life easier but ends up being a daily frustration.

What's in this rack? A clean, organized system built around URC Total Control, Luxul network, Marantz receivers, Wattbox power management, and a JVC Projector— all integrated so the homeowner runs everything from one interface. No juggling five apps to watch a movie. No confusion about which remote does what.

That's what professional integration looks like. Every component chosen for a reason, every connection purposeful, and the whole thing tailored to how this family actually lives.

After 30+ years of doing this, I can tell you: the best technology is the kind you never have to think twice about. Seamless. Easy to use. Future-ready.

Another media room wrapped up today. Give us a call for your media room project. 972-757-4002

We’ve taken another media room to a new level. This project was wired by some one else(they mark their territory with stickers) but we changed it up a bit. First we moved the speakers that were misaligned on the flat ceiling and put them in more ideal listening positions. Then we retro fit 7 light strips including around the screen. All located in a rack in the closet with Savant Automation calling the shots. 7 Martin Logan speakers fed by a Denon receiver and one SVS Sub shaken things up quite a bit! Give us a call 972-757-4002.
