About Multi Way Speakers
A Multi-Way Speaker system is a type of loudspeaker system that employs numerous speaker drivers to generate sound across a wide frequency range. Unlike single-driver speakers, which rely on a single driver to handle all frequencies, multi-way systems distribute the frequency range across numerous drivers, each specialized for a certain range.
Usually, a multi way speaker system has at least three drivers –
- Woofer from 16 Hz to 500 Hz
- Tweeter from 5000 Hz to 20000 Hz
- Squawkers from 500 Hz to 5000 Hz
1. Woofer
A woofer is a driver that produces low frequencies (16 Hz to 500 Hz). The driver combines the closing design to provide appropriate low frequencies. Some loudspeaker systems use a woofer for the lowest frequencies, which works well enough that a subwoofer is not necessary. These can work up to several thousand Hertz, although their output becomes very directed at high frequencies. Woofers have big, hefty diaphragms and voice coils that overhang the magnetic gap. It is used in conjunction with a “tweeter” and crossover network to provide a range of frequencies for audio reproduction.
2. Tweeter
A tweeter is a high-frequency driver that generates the highest frequencies (5000 Hz to 20000 Hz) in a speaker system. There are many different types of tweeter designs, each with its own set of capabilities in terms of frequency response, output fidelity, power handling, maximum output level, etc. This might be ribbon, electrostatic, or dynamic. Soft-dome tweeters are extensively used in household stereo systems, and horn-loaded compression drivers are prevalent in professional sound reinforcement. Ribbon tweeters have grown in prominence in recent years, as their output power has been boosted to levels suitable for professional sound systems, and their horizontal output pattern is wide, making them appropriate for concert sound applications.
3. Squawkers
To obtain flat frequency response over the whole spectrum of audio frequencies, multi-way loudspeakers are employed. Squawkers are used to replicate medium-frequency signals (500 Hz to 5000 Hz). A commercial three-way divider network is employed in the squawker system.
