When you’re getting into the world of DJing, sound matters. Maybe you’re wondering how to get the best possible setup. You’ve already got a pair of cool DJ speakers. You’re ready to blast your beats. But then someone asks, “Do you have a subwoofer?”
You pause. Do you need one? And if so, why?
We’re here to break it down for you in the simplest way possible.
What’s a Subwoofer, Anyway?
A subwoofer is a special kind of speaker made just for bass. That’s the low, deep boom you feel in your chest when the music drops.
DJ speakers, or PA speakers, try to cover all the sound. That includes high notes (like cymbals), mids (like vocals), and lows (like basslines). But they can only go so low.
Subwoofers focus only on the low frequencies. Think 20 Hz to around 120 Hz. That’s the rumble. The power. The thunder.
So… Do You Need a Subwoofer?
The short answer? It depends. But let’s go over some examples to help you decide.
You Might Not Need a Subwoofer If:
- You’re playing at small house parties or coffee shops
- Your music style doesn’t rely a lot on bass (like acoustic or folk)
- You already have full-range speakers with decent low-end response
For chill, laid-back gigs, your DJ speakers might do just fine on their own.
But You’ll Want One If:
- You play bass-heavy genres like EDM, hip hop, or techno
- You want the crowd to feel the music, not just hear it
- You’re playing in large spaces or outdoors
- You want cleaner sound overall

Adding a subwoofer takes the pressure off your main speakers. They’ll sound clearer because they don’t have to push those low booms anymore.
What Do Subwoofers Actually Do to Your Sound?
Imagine a song drop without the thump. It might sound okay, but it won’t feel right. The kick drum might sound like a mild tap instead of a punch in the gut.
A subwoofer brings that impact.
Here’s what adding a sub does for your sound:
- More bass – obvious, but it matters!
- Cleaner mids and highs – your main speakers have more room to breathe
- Balanced sound across the room – especially in big venues
- Happy dancers – everybody loves the boom
How Many Subwoofers Do You Need?
Most DJs start with one subwoofer, usually placed in the center front. It’s enough for most events.
If you’re doing large venues or just want better bass distribution, add another sub on the other side. Two subs can reduce dead spots and make things thump evenly.
Want to go big or go home? Add more! Just be sure your room – and your neighbors – can handle it.
But Wait, Won’t It Be Harder to Set Up?
Good question. Not really. Today’s subwoofers are easier than ever to use.
Many powered subwoofers come with:
- Built-in crossovers
- XLR connectors
- Easy volume controls
- Phase switches
Just plug your DJ controller into the sub’s input. Then send the output to your speakers. Boom. Done.
Size Matters (But Not Always)
Subwoofers come in different sizes. A 12-inch sub is good for small to medium spaces. For big events, you might want 15 or even 18 inches.
Bigger generally means more low-end power. But it also means heavier gear. Pick what works best for your setup and your back!

Powered vs. Passive Subs – What’s the Deal?
Powered Subwoofers:
- Have built-in amplifiers
- Are plug-and-play
- Don’t need an external amp
These are perfect for mobile DJs or beginners. No hassle, less gear to carry.
Passive Subwoofers:
- Need an external amplifier
- Offer more flexibility
- Often used in permanent installs or complex rigs
If you’re just starting, go with a powered sub. It’ll save you headaches.
Can You DJ Without a Subwoofer?
Of course! You can DJ without it, and many people do.
But once you hear the difference, you might never want to go back.
You’ll notice more energy on the dance floor. People feel more involved in the music. And your entire sound just feels complete.
When’s the Right Time to Get One?
If you’re still learning the ropes or playing small events, you can hold off.
But if you’re:
- Getting booked at bigger venues
- Sick of weak bass
- Trying to take your sound to the next level
Then yes—it’s time.
Pro Tip: Try Before You Buy
If you get the chance, test some subwoofers before buying. Different brands sound different. Some have a punchy vibe, others are more rumbly. It depends on the style of music you play and how you like your bass to feel.

Final Thoughts
So, do you need subwoofers with your DJ speakers?
Not always. But boy, can they make a difference.
If you’re serious about sound—and especially about bass—a subwoofer is worth it. Your beats hit harder. Your mix feels bigger. And the crowd feels everything.
It’s not just about making music. It’s about making people feel the music. And that’s what being a great DJ is all about.
So if you can swing it, go get that sub. Your fans—and your ears—will thank you.
