Pro Audio PA Speakers

Whether you want them for your home to improve the sound quality of your music, movies and TV shows or have a business that relies on quality sound to serve your customers or patrons better, top-notch speakers are the way to go. When setting up a stereo system or public address (PA) system, you can have the best-quality sound source like a stereo system and negate the entire setup with the wrong type of speakers or poor-quality speakers.

What is pro audio?

Professional audio is different than home audio, although it is entirely possible to set up pro audio equipment in a home environment. For example, many stereo setups use an amplifier or preamp as part of a home stereo system. However, depending on the space, the amplifier is not always necessary. However, in a pro audio setup, amplification is necessary. Depending on the use, the sound source in a pro audio setup, such as a receiver, turntable or stereo, is passed through an amplifier before reaching the speakers. In more advanced setups, the sound source is passed through a PA speaker before going through a PA amplifier and then out through the speakers, which gives more sound options and control to the user. Other parts of pro audio systems can signal processors for effects like reverb and delay, equalisers that raise and lower the sound frequencies and microphones.

What are PA speakers?

One of the most important aspects of PA speakers is their portability. PA speakers are more stationary than home audio speakers. DJs, musicians and venue owners, as well as homeowners who are audiophiles, are constantly striving to find the best way to deliver sounds to their guests and PA speakers make that possible. In most cases, these are larger and heavier than typical home speakers and designed to deliver specific frequency ranges. Some examples of PA speakers include active PA speakers (also known as powered PA speakers), which have a built-in amplifier, or passive PA speakers, which are not powered and do not have an amp.

What are some types of PA speakers

There are several types to consider when choosing PA speakers. These include:

  • Woofer
  • Mid-range
  • Subwoofer
  • Tweeter

Subwoofer PA speakers reproduce sound at the lowest frequencies, which ranges between falls around 30 Hz to 300 Hz. The woofer type reproduces frequencies in the low range below 500 Hz. Mid-range PA speakers reproduce frequencies in the mid-level range of between 200 Hz and 20 kHz. Tweeters reproduce frequencies at the highest level, which is generally between 2 kHz and 20 kHz. The size and type of the PA speaker's driver correspond directly to the type of speaker. For example, a subwoofer used a cone-style driver that is 38 to 61 centimetres in size. A woofer speaker uses cone-type drivers that are between 25 and 50 centimetres. Mid-range speakers use either a cone driver that is 13 to 30 centimetres or a compression driver that is 6 to 10 centimetres. Tweeters use the smallest drivers, either a 2.5- to 5-centimetre cone-type driver or 2.5- to 10-centimetre compression-style driver.
