You might like to know that you’re buying the right equipment and getting it at a fair price. **WE SPECIALIZE IN HOME STEREO AND THEATRE SYSTEMS**There's a proven way to do that - good planning. With 20 years professional experience I know what to ask you whether you’re an avid enthusiast or a novice. I know what to look for in your home (i.e. infrastructure). And, we talk. After we're done planning, you've got one very solid solution. (And, this is what I love doing!) A manufacturer-authorized dealer, you pay no more for product bought through me than you would from a brick-and-mortar store. You benefit from my lack of overhead expense - mine is a home-office - by paying less for installation. You get my support after the sale so you don’t have to deal with frustrating tech-support lines. DH Audio and Home Theater offers wired and wireless speakers, TVs, home theaters, acoustic room treatments, equipment cabinets, and Wifi-Network systems.

"Dennis was very professional and comprehensive. He was prompt and paid attention to our individual needs. He made sure that everything was working properly and that we were comfortable using all the equipment. I would strongly recommend his services."

Welcome to Ultimate Computer! My name is Joe. I've been a computer professional for over 24 years in major service companies like BancTec Service Corp and Integrated Designs as Senior Field Service Engineer. I managed small business client accounts in the late 1980s and the 1990s in New York City and New Jersey. I moved on in the late 1990s to work in major bank "BNY Mellon" firm in the Information Technology sector handling server/networking infrastructure. I had a major role in data recovery after 911 for the firm. I have established good relationships with my clients over the years through my values of respect, integrity, professionalism, and getting things done. Then word got around, so individuals contacted me to set-up desktop/window server infrastructure for their offices and homes. Ever since then, I have been running Ultimate Computer. Call now for an estimate!

"Quick response and great service at a reasonable price. Would highly recommend"

Stereo and Home Theater Systems questions, answered by experts

For optimal sound distribution, position the front speakers equidistant from the TV, the center speaker below or above the screen, and the rear/satellite speakers behind or to the side of the listener. The subwoofer can be placed anywhere but may sound best in corner areas.

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.

Yes, upgrading single components like the receiver or speakers is possible, often leading to improved audio quality. Ensure compatible specifications with existing equipment for a seamless integration.

Consider the room size, speaker wattage/output, personal sound preferences, and budget. High-quality speakers with appropriate power ratings for your room will deliver a better audio experience.

Your home theater cost will vary depending on the components you choose, from brand to features. For example:

  • 4K 50-inch to 60-inch TV: $800–$1,500

  • 60-inch TV and bracket: $900

  • Amplifier: $250

  • Five box speakers and subwoofer: $500

  • High-end front projector: $10,000–$60,000

  • Home theater screen: $250–$1,500

  • Low-end front projector: $1,500

  • Surge protection: $25 and up

  • Three HDMI cables: $30

  • Universal remote: $20–$200

  • Wiring and circuit board: $400–$2,700
