Loudspeakers are probably one of the most expensive components of any audio system. Therefore, it makes sense to think twice when purchasing a specific model. Prices of loudspeakers range from tens of dollars to tens of thousands of dollars. There’s a huge span and thus the quality of each model differs a great amount. Aside from the quality, you also need to consider certain factors in order to determine whether a particular loudspeaker is a good choice for your system.
First of all, you need to figure out whether you want to purchase a full-frequency speakers or smaller speakers along with the subwoofer. Second of all, you will need to determine whether you want regular speakers or wireless speakers such as wireless subwoofers. Most home theater systems nowadays utilize fairly small speakers instead of full-frequency speakers. Therefore, these systems usually incorporate a subwoofer. The subwoofer will be able to reproduce the low-frequency sound components which the satellite speakers are missing.
However, for audio playback I typically recommend to purchase instead full-frequency speakers. The speakers have been well-designed and the sound is more balanced versus working with satellite speakers and a subwoofer. The audio fidelity would typically be superior to working with the subwoofer. As always, do a test and you will be able to figure out which type of speaker works best for you.
Also, keep in mind that different speakers have different types of impedance. The impedance determines what type of amplifier you will need to drive the speakers sufficiently. In addition to impedance, you should also note the speaker wattage. The speaker wattage will also determine how strong the amplifier that you will require has to be. Obviously, you don’t really want to drive the speakers to maximum wattage. That can cause irreparable damage. But then again, the power amplifier usually would never be driven fully because distortion will go up very quickly as you reach the maximum specified amplifier wattage.
Therefore, you have to keep the speaker wattage should balance with the amplifier wattage. Another important factor when purchasing loudspeakers is the speaker sensitivity. The sensitivity determines how loud a speaker will be relative to the wattage that is being supplied. Higher-sensitivity speakers have the advantage that they don’t require very strong amplifiers. However, one drawback is that often you will hear background noise which is generated by the amplifier more than with other types of loudspeakers.
