Stereo and Home Theater Systems questions, answered by experts

Installing a new home theater or upgrading your current one will likely add value to your home, as many prospective buyers will consider it an exciting bonus feature. However, the value of a home theater is subjective and depends on the buyer, so there’s no guarantee that it’ll increase your home sale value. Keep in mind that home theaters typically have a return on investment rate of about 65%.

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.

Common problems include poor audio quality, connectivity issues, and malfunctioning components. Regular maintenance prevents many issues.

Costs range from $1,000 to $5,000, depending on system complexity and components.

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.
