About This Quiz

While buying an all-in-one home theater (also known as home theater-in-a-box, or HTIAB) simplifies a lot of your decisions about components, there's still a lot to learn about home entertainment technology. Think you know the ins and outs of home theater systems?

When reading up on speaker systems, what does the number after the decimal point mean?

A subwoofer is a speaker that specifically transmits bass frequencies. The number after the decimal point in a speaker configuration -- in, for example, a 5.1 or 7.2 system -- describes the number of subwoofers it has.


The subwoofer channel transmits bass sounds. What's the frequency range for those signals, in hertz?

Bass frequencies fall within the 20 to 200 Hz range.


What color is the laser used in a Blu-ray player?

As the name suggests, Blu-ray uses a blue laser to read its high-def discs.

Most remote controls use infrared signals to communicate using an LED (light-emitting diode) in the handset, although Bluetooth is an increasingly popular wireless choice.


To what connection system in your home does the 802.11 standard refer?

Wireless internet (WiFi) devices use the 802.11 standard to communicate with each other.

What does "HDMI" actually stand for?

HDMI stands for High Definition Media Interface, and connects HD video and audio to your device without compressing the signal.
