Resume: what characteristics you have to know when you buy a subwoofer. Part 3

What characteristics you have to know when you buy a subwooferFrequency range is displayed in Hertz (Hz) — is limiting the range of reproducibility to deliver the necessary frequency of the subwoofer, which are divided into several octaves: low bass 20–40 Hz, medium-tions the range of 40–80 Hz and high-frequency range 80–160 Hz bass. The vast majority of subwoofers sound in the range of 40–200 Hz, that is, basically — medium and high bass. The ideal frequency response for the subwoofer speaker — 30–60 Hz. The lowest bass will not play for the stage itself.

Crossover frequency — a frequency at which it is frequency separation. If the subwoofer has a frequency separation of 70 Hz, the crossover, with some steep medium for, “separates” all sounds with frequencies that are greater than 70 Hz. In most cases, cross-faith configured on the amplifier. For the convenience of a crossover built into car radio medium-size and expensive price range, and for maximum functionality and flexibility in setting the bass to buy a separate sound processor.

Maximum sound pressure — is the ultimate volume of the subwoofer. Typically, this option is used to measure sound pressure in Car Audio competitions. If you need just the right quality and bass - this parameter can be neglected.

Sensitivity. It is recommended to select speaker system with a sensitivity of 90 dB and above. With a good indicator of sensitivity, you can use lower power amplifier. The greater sensitivity of the speakers, the less loaded with amplification, amplifier, and thereby increases the overall volume of the system in which sound is not distorted.

The diameter of the subwoofer, designated in millimeters or inches, and, as has already been writ-ten before, the best of its size — 10–12 inches. In some cases, are trying to use a pair of 8-inch subwoofer speakers. For example, in the rear shelf car Daewoo Lanos can cleanly install a pair of subwoofers DLS Performance OA8. This “sweet couple” will play a very nice and soft.

Natural frequency — is the internal dynamics of the resonance frequency without the acoustic accompaniment. Resonance depends on its own physical characteristics: weight of movable parts, and suspension stiffness. Ideally, it is better that this frequency was outside the limit of frequency response speaker.

So, after reading our articles about the subwoofer range and bearing information about the technical characteristics of the, you easily can choose high-quality subwoofer and buy it in the internet-store “130”.
