Five Mistakes That Kill Home Theaters Before They're Born
Why Professional Design Is the Difference Between “Pretty Good” and “Wow”
You’ve got the space. You’ve got the budget. You’ve dreamed of immersive movie nights with your favorite people texting, “When can I come over again?”
But here’s what often happens instead:
You mount the biggest screen you can afford. You hook up speakers, and maybe even splurge on a subwoofer. Six months later, you’re adjusting the volume every ten minutes because dialogue sounds like mumbling, the bass shakes your walls, and that pricey projector overheats during the climax of nearly every action movie.
Unfortunately, this is the reality of DIY: finding good deals and some time on the weekends, then creating a piecemeal home theater setup that simply doesn’t cut it.
At Launch Systems, we’ve designed and installed hundreds of high-performance home theaters across Southern California. We’ve seen the pitfalls of DIY and subpar AV system design, and we’ve often fixed the aftermath of big, bold do-it-yourself ideas that simply don’t make it to the finish line.
We know what elevates a theater from basic to brilliant, and we’ve compiled a list of the top five most common mistakes we help clients avoid.

1. Speaker Placement Based on Aesthetics, Not Acoustics
Here’s a $10,000 mistake: putting your speakers where they look good instead of where they sound good.
Most DIY setups place speakers wherever the furniture or architecture allows, sometimes above a doorway, tucked behind a couch, or awkwardly angled in a corner. One viewer may experience great sound, while everyone else gets echoes, muddled dialogue, or boomy bass.
Instead, take a comprehensive look at your room dimensions, seating layout, and acoustics, then calibrate the system so every seat sounds like the sweet spot.
2. Forgetting That Walls Reflect Sound
You can invest in stunning equipment, but if your theater has bare walls, hard floors, or too much glass, it will sound harsh and echoey.
What you’re hearing in those instances is the sound bouncing around the room. Your brain tries to process the direct and reflected sound simultaneously, and the result is auditory fatigue.
That’s why acoustic treatment is essential. Use professional-grade absorption and diffusion—no, not foam tacked up in every corner—to refine the sound without killing the immersive movie vibes. The goal should be clarity, not silence, so the room practically disappears so you can focus on the film.
3. Overheating Your Equipment (or Your Guests)
High-end AV gear generates heat. If you stick a receiver or gaming console inside a cabinet with no ventilation, it’s only a matter of time before performance degrades or something shuts down.
Instead, design airflow into every install. That means intake and exhaust systems, whisper-quiet fans, and intuitive temperature control that kicks in before anything gets too hot to handle.
Even your guests benefit: a well-designed theater includes HVAC planning. Pack eight people into a sealed room, and suddenly you’ve got a sauna, so be sure to integrate climate systems to keep everyone comfortable without noise disruption.
4. Choosing Equipment Without Thinking About the Room
Buying the biggest screen or loudest speakers your budget allows is tempting, but that approach rarely delivers the best results.
Why? Because your equipment selection and placement must be as unique as your genre favorites and fit the room’s layout. A projector designed for a light-controlled space won’t perform well in a bright, multipurpose living area, and speakers sized for a large home theater might overwhelm a media room.
Assess your space, goals, and lifestyle, then build a solution that suits it. That’s how to turn good investments into great home theater experiences.
5. Ignoring the Future
Most gear works great, but what happens when you want to add voice control, connect to streaming sources, or integrate smart lighting?
Many DIY theaters are built without expansion in mind. Wires are buried, components are locked in, and adding or upgrading at a later date becomes messy or impossible.
Design the space with the future in mind. Use scalable wiring infrastructure, modular components, and system designs that can grow with your content preferences and device advancements. Whether you add outdoor audio or sync lights to your movie scenes, you’ll be ready for whatever’s next!
