What Is A High-Efficiency Speaker?
High-efficiency speakers, also known as high-sensitivity speakers, are a type of loudspeaker that can produce high sound pressure levels (SPL) with only a few watts of amplifier power. The sensitivity rating of a speaker, measured in decibels (dB), indicates how loud a speaker will play with 1 watt of power input. While most conventional speakers have sensitivity ratings of around 86dB, high-efficiency speakers exceed this rating and require less amplification. This means these speakers can get incredibly loud even when powered by a low-wattage tube amp. Just a speaker rated at 88dB can result in a noticeable improvement in reaching loud volumes.
Some audio enthusiasts seek out high-efficiency speakers for several key reasons. First, they allow you to achieve room-filling volume without paying for an expensive, more powerful amp. Purchasing an amp and speakers can add up. That’s before considering other equipment, such as a DAC or subwoofer, which might be required for a high-end audio setup that covers a full range of frequencies. This makes it ideal for targeting a high-efficiency speaker since ideal it could save money for shoppers on a budget. Those in search of home theater speakers will also need to power many multiple speakers. If you want a larger home theater, speakers with higher sensitivity will also be desirable. A high-sensitivity speaker will help in reducing the strain on your AV receiver. A bad combination of amp and speaker with low sensitivity might only be suitable for small rooms.
A high-sensitivity speaker can make the difference in delivering enough volume needed for a larger listening area. We’ve compiled a list of the top speakers with high efficiency. These are the best speakers for low-powered amps or those who just want to ensure high volumes with moderate wattage.
