A Guide to Choosing the Right Speakers for AV Receiver/Amplifier

When you want to install a music system, you will need to make the right choice of speakers to match with the specifications of the receiver/amplifier. Although there are different types of speakers in the market, it is necessary to understand the specifications of each before making a choice to buy. If checking to confirm on ones that are reliable proves too technical, you can involve an expert to help you match the right speaker with your amplifier. Here are things to consider when searching for the right speaker for an AV receiver/amplifier.


Impedance measures the level of demand a speaker places on the amplifier. It is measured in Ohms ranging from 2 to 8. Speakers with high impedance place more demand on the amplifier, so matching the two to avoid problems is necessary. This affects the quality of sound produced. For instance, speakers that are designed to offer 6 Ohms, when connected to an amplifier of 8 Ohms would lead to less than dynamic sound. This is attributed to the fact that the load placed on the amplifier is more than it can handle. Having the wrong set could lead to damage on the amplifier. One of the most common complaints of mismatching speakers to amplifiers is that they shut down at extreme sound waves. Normally, the amplifier gets imbalanced at such levels, thereby causing distortion of sound and in extreme cases the system shuts for some time.

Power handling

Measured in watts, power handling is among misunderstood specifications that matter. The figure reflects the amount of power the speaker can handle comfortably for a certain period. Depending on the type of waves being transmitted, the speaker may attain a certain maximum limit, beyond which it may have problems working. Although PMPO may be used to gauge the functionality of a speaker, it is often overrated by manufacturers and can mislead the buyer. So it’s more advisable to rely on the power handling value to know which speaker to buy for your AV receiver/ amplifier.


Sensitivity is measured in decibels (dB) and represents the ability of the speaker to convert the power transmitted from the amplifier into sound. Speakers with a higher rating are more stable and can handle waves of different magnitude comfortably. Most speakers come with a rating of 87 to 93, but anything above 90 is considered stable enough to handle all types of power from the amplifier.
