Here are a few, simple points that you need to keep in mind whole you go subwoofer shopping.
The Size Factor
The size of the subwoofer is one major factor that tells the sound output from it. A larger size woofer typically shows that the product gives a greater amount of bass. The space that is available in the car is also one other important factor that plays into the subwoofer in the right way. So, it is advisable that you get the measurements right and check the dimensions, too before you settle on anything. The standard size for speakers is 8, 10, 12 m and 15 inches in diameters.
The power of the subwoofer is one other major factor that tells the output. The RMS power ratings of the subwoofer is an important feature that you should note, and the higher that it is, the louder the speaker will be. You should keep in mind that the subwoofer also needs just the right amplifier that is sure to deliver the right power from the receiver to the speaker. So, if you get a high-powered speaker, you should ensure that the amplifier can handle that amount of power.
There are some other important features that need to be taken into consideration while you buy a subwoofer and these features are sensitivity, impedance, frequency range, and a number of voice calls. The subwoofers with a higher sensitivity rating usually need less power to be able to make the same amount of sound. Matching the impedance of the subwoofer with the amplifier can result in a very huge improvement of the delivery of the sound. Frequency tells you the range of sound the subwoofer can make, and it is advisable that you choose a unit that gives low on the scale. Subwoofers usually come in single and dual voice coils and dual voice coils make more flexibility for wiring the system.
