Receiving fantastic sound from your setup entails that the needs of your speakers are matched up with the capabilities of your receiver. Now that you’re an expert at recognizing the performance of the best AV receiver with respect to processing and power, it’s time to think about what your speakers require to be at their best. The best approach for this is to check out some speaker specs;

Impedance – the impedance of your speakers is the amount of resistance that is accorded to the signal of your receiver. The typical impedance rating at which speakers can play fantastic with a wide range of receivers is 8-ohm. However, the moment that figure starts to drop, an increasing amount of stable power will be required.

SPL/Sensitivity – The sensitivity on your speakers denotes how loud they play at every watt of power. The resultant Sound Pressure Level (SPL) is identified in dB (Decibels). A speaker that has low sensitivity will require more power for it to play as loudly as one with high sensitivity. Normally, a majority of speakers stay between the ranges of 85dB to 95dB per watt, although there are some exceptions at both ends of the scale. If your speakers are on the low end, get a higher-powered receiver to have them perform optimally. Be aware that sensitivity does not suggest sound quality, it just means that your speakers can play louder at less power.

Bandwidth – Basically, the more bass you want your speakers to supply, the more power they’d require. Throwing the self-powered subwoofer into the mix has taken a lot of that responsibility off the best AV receiver. Systems that utilize satellite speakers while leaving the earth-shaking job to the subwoofer, don’t need as much power from the receiver. Those who use full-range speakers that give off a lot of bass will most likely require more power.
