WHAT IS THE DIFFERENCE BETWEEN PASSIVE AND ACTIVE SUBWOOFERS

DEFINITION OF PASSIVE AND ACTIVE SUBWOOFERS 


passive subwoofer is extremely simple in design - it consists of a cabinet and one or more woofers, which are then connected to an external amplifier. There are also two types of passive subwoofer connections. The first type is the least preferred due to the presence of sound distortion and lower quality of its transmission - in this case, the stereo amplifier signal is fed not only to the subwoofer, but also to the rest of the speakers. Connecting with an electronic crossover filter is much more reasonable because it effectively separates the bass from the signal going to the other speakers.

The active subwoofer includes both a crossover filter and a power amplifier. Thus, an active subwoofer is a mobile combination of several devices that can be found separately. The active subwoofer has line inputs and outputs, as well as a function to adjust the signal level and crossover frequency. As a rule, a good active subwoofer significantly expands the dynamic range of the speaker system, which, of course, will have a beneficial effect on the quality of the music.

COMPARISON OF PASSIVE AND ACTIVE SUBWOOFER

Firstly, an active subwoofer with its standard settings is on average better suited for heavy or dance and rhythmic music, since it transmits bass frequencies better and has more flexible settings and adjustments (except when using an expensive speaker system and a very high-quality passive subwoofer ). Secondly, active subwoofers have their own amplifiers, while passive subwoofers need external amplifiers. However, it is possible to tune a passive subwoofer system to sound better than an active subwoofer system, but this is a very painstaking and delicate process. In this regard, an active subwoofer is much more convenient, because it is much faster and easier to set up, but many connoisseurs of good sound prefer to spare no time and effort to set up passive systems.

THEDIFFERENCE.RU DEFINED THAT THE DIFFERENCE BETWEEN A PASSIVE AND ACTIVE SUBWOOFER IS THE FOLLOWING:

An active subwoofer has a built-in amplifier. A passive subwoofer needs to be connected to external audio amplifiers.

Setting up a speaker system with an active subwoofer is much faster and easier.

When tuned as accurately and as accurately as possible, a system with a passive subwoofer will usually produce a more spacious and dense sound than a system with an active subwoofer.
