Beginners Guide to PA Speakers

It’s that time of year again—with the holidays are just around the corner, everyone is in a celebratory mood. If you find yourself wanting to buy a sound system and have no idea where to start, then this beginner’s buying guide will be of great help. For a beginner system, I highly recommend a powered speaker because they contain the built-in amplifiers that are optimized for the best sound. You don’t have to worry about calculations or providing additional equipment like amp racks and heavy speaker cables. Some powered speakers include built-in mixers that can accommodate a variety of inputs including microphones, line-level, and Hi-Z instruments (guitar), as well as integrated Digital Signal Processing (DSP) to help fine tune the sound.

Before we dive into some recommendations, let’s first talk about some performance specifications that will help you determine what speaker would be best for your application. The most important specs to know are Frequency Response, SPL, and Dispersion.

Frequency Response

  • Frequency response is the range of sound that the speaker is capable of reproducing. In layman’s terms, think of it as treble and bass on your stereo. How low does the bass go and how high does the treble go.

SPL

  • Sound Pressure Level (SPL) is how loud of a sound the speaker can output. There is nothing worse than having a speaker with low output, as you’ll overdrive and distort the sound trying to squeeze as much output as possible.

Dispersion

  • Dispersion is the way the sound is projected horizontally and vertically from the speaker. This is useful for determining the placement of speakers since you can direct the sound away from boundaries, such as walls and ceilings. Knowing the dimensions of the room or coverage area will help inform your speaker selection. For example, you wouldn’t want a wide dispersion speaker in a narrow room because the sound would bounce off the walls and create reflections that can muddy the sound. And a narrow dispersion in a wide room will leave a lot of uncovered areas.

Unfortunately, Mackie didn’t include the dispersion, but from my personal experience, it’s probably close to 90x50°. The mixer features two combo XLR-1/4" mic/line channels, a 3.5mm stereo input, and an XLR output for daisy-chaining additional speakers. Notable features include music ducking for making announcements and a feedback eliminator that mitigates microphone feedback automatically.
