3 Factors To Consider When Shopping For Home Theater Speakers

With so many specifications on home theater speakers, it can feel overwhelming deciding on which one is best for you. By understanding these 3 factors, you’ll know what you should be looking for.


The impedance is the amount of power that the speaker will pull from the amplifier, which is measured in ohms. It’s typical to see speakers in a range of 4-8 ohms when shopping for consumer speakers for a home theater.

What you want to make sure of is that the amplifier is not too powerful for your speakers. Look at the technical specifications for your amplifier, and verify that it will support the speakers that you are selecting in terms of its impedance. Selecting a cheap speaker that is not powerful enough could cause the amplifier to blow it out.

Frequency Response

The frequency response is the range of sound frequencies that the speaker can produce, which can range from around 10 Hz to 30,000 Hz. A speaker with this frequency range will allow you to hear the lowest bass sounds, as well as the sounds in the highest pitches.

Getting a speaker with the largest frequency response may be overkill though. The typical human ear can only hear between the frequency response range of 20-20,000 Hz, with each person having a different frequency response range. The only way to know if you can hear all the frequencies of a high-end speaker is to hear them yourself. If you cannot hear the difference between a speaker that tops out at 15,000 Hz or 30,000 Hz, purchasing one with the specs of the latter may be wasting money on a speaker you could never take advantage of.

Also, consider that your subwoofer is going to make up for surrounding speakers that do not go very low in frequency. Dialogue can have a very high frequency, so select a center speaker that has a big frequency response range to ensure vocal clarity.


The dispersion is communicated with a circular diagram that shows the range that a sound will fall off at difference frequencies. Low frequencies have a high dispersion, meaning that all people in the room will be able to hear them. High frequencies have a narrow dispersion, which causes the sound to be directional coming from a speaker.

You must consider the setup of your room when looking at the dispersion. Is your home theater set up for one person sitting in a single spot, or an entire room of people spread out around a room? If it is the latter, you’ll need speakers with a bigger dispersion in the higher ranges so that everyone can hear voices clearly.

Once you have your speakers selected, the next step is to have them professionally installed to ensure that they are set up properly. Contract a professional in your area to help you.
