All About Column Arrays

Today we want to answer a couple of pretty common questions about column array speakers, specifically our TRC Systems. It’s fair that these questions get asked because when any musician thinks of PA speakers they picture more traditional speaker enclosures. But, column arrays can be just as good as, or even better than, traditional PA speakers. So let’s dive into it...


The column array gets its name from its speaker orientation: multiple small speaker drivers, arranged vertically, in a tall and narrow enclosure. They kind of look like a Tetris piece don’t they?
Essentially, they provide the same kind of performance as large line array systems used in arenas but without the huge size and expensive price tag.


Like everything related to music and audio the word “better” is subjective. However, we do have an affinity for column array speaker systems for several reasons:

  1. Aesthetics: due to their slim design, column arrays aren’t as eye catching as larger speaker enclosures. The whole point of live performance is to keep all focus on the performer and not the equipment. Without any distractions to divert their attention the audience focuses more on the performance happening on stage.

  2. Portability: have you ever had to carry large PA speakers up a flight of stairs or long distances? Has your truck or van been packed too full for any more gear? Yep, we’ve been there too! Thankfully, column array systems are much easier to handle. Many feature lightweight designs allowing for ease of transport and their smaller size makes for more room in your vehicle. Some, like our TRx3900 speakers, even have custom gig bags or cases to make for easy transport.

  3. Consistency of Sound: one of the interesting things about sound is how greatly it can change based on your location in a venue. Sometimes everything sounds great up at the front row and muddy or dull at the back row. And then the opposite can happen! Thankfully column arrays give you consistent sound throughout most any venue. The design delivers an equal sound level from front-to-back and ensures everyone in the venue gets the best experience possible.


When developing the TRx Series and the TRC Systems we considered some of the shortcomings of a column array speaker system.
Due to the smaller size of the speakers in the enclosures column arrays don’t produce a lot of low end. While this can be good for events where clarity of speech is important it doesn't make for the best audio system for bands or DJs. The simple solution is to add a good subwoofer and we’ve done just that by adding the TRx3118A to the TRx Series, which includes a built in DSP and a 2000W power amp to power both the sub and 2 columns. We recommend purchasing both the column arrays and subwoofers together as a TRC System package. These systems are scalable, so you can start with the 2000W TRC200A System and add a second system or extra subs later for a system with up to 6000W!

Also, most column arrays have to be positioned physically to get the correct projection for a venue. This task can often require professional installation, which gets expensive. We know many of our customers are looking for simple solutions to their needs. Our TRx3900 speakers use Constant Delivery Dispersion (CDD) technology that helps project sound throughout the venue. This CDD tech creates a wide horizontal spread, meaning the sound is consistent throughout the audience.

And the best part is you can set it all up yourself! Professional quality sound for everyone.


Having said all this, do we consider Column Arrays to be the be-all-end-all of PA Speakers? Absolutely not. There’s a time and place for other types of PA speaker systems. What works for you doesn’t necessarily work for the other person. As anyone can see, we offer much more than column arrays speakers on our website.

Ultimately, it’s best to do your homework. Research, learn and (once we can all go back to live venues) listen! You’ll find the answers before you know it.

Take care friends and we’ll see you again soon!

There was a time not so long ago that a band or solo artist would have to hire a real-live studio to record anything. Those days are gone, but it doesn’t mean studios are gone and it doesn’t mean recording doesn’t cost anything now. Since many projects might require a combination of home and studio recording, there are still studio fees to think about, and home recording gear isn’t free.

So, here are five ways to save on recording costs, no matter how you go about things.

There’s obviously no more important piece of audio equipment than the speaker – the way we actually hear recordings or the amplified signal from microphones on stage. But unless you make speakers for a living, you may not have much cause to open one up and study the insides – even though it might be nice to understand a bit about them.
