Growing up, I was captivated by the magic of movies and entertainment. They weren’t just about watching a screen—they were about creating moments that brought my family together, filled with laughter, excitement, and connection. Those memories stay with me, and they inspire everything I do. When you work with me, you’re not getting a dispatcher or a customer service representative. It’s just me—someone who truly cares about helping you recreate those special experiences for your own family and loved ones. My goal is to ensure every event and service feels personal, memorable, and filled with the same joy I experienced as a child.

"I have nothing but praise for Peterson’s low voltage systems. I was a little overwhelmed and Mike guided me on the best system and set up for our needs. His professionalism, value and customer service all unmatched. "

Stereo and Home Theater Systems questions, answered by experts

Professionals calibrate the system for immersive audio, eliminating sound delays and improving acoustics.

The biggest and best home theaters are 24 by 15 feet, but in smaller spaces you can make do with 15 by 20 feet, 10 by 12 feet or even smaller. You should aim for a ceiling height of about 9 feet. Remember, the size of your theater will affect layout, projector placement, screen size and other factors.

Yes, professionals can mount in-wall or ceiling speakers for a clean, seamless look.

The length of coax cable can affect the signal. Coax cables and their connectors all have a small amount of electrical resistance, which means that the longer the cable and more connectors in the system, the weaker the signal strength. In most homes, the signal loss is tiny, but systems with coax cable lengths over 100 feet will likely experience signal troubles.

DIY is possible, but professional installation ensures optimal speaker placement and wiring.
