SOUND LIKE YOU’VE NEVER SEEN
SuperFreq is a compact, high-fidelity sound system built for people who actually listen. Designed for tight city spaces, it delivers the richness and presence of live music—without filling your home with bulky gear. Every detail is tuned so the speakers disappear and the music takes over, from crystal-clear highs to bass you can feel in your chest.
BASS LIKE YOU’VE NEVER HEARD
This isn’t your typical rumble box. The SuperFreq Subwoofer is a vertical marvel—an elegant, space-saving pillar designed to disappear into the corner of your apartment while anchoring your music with deep, articulate bass.
Instead of shaking your walls, it plays with your mind. Using quarter-wave resonance techniques, it delivers bass that feels perfectly connected to the music—tight, immersive, and emotionally present. Super fast bass. No booming one note. Just beautifully integrated low-end that follows the groove like a shadow.
Whether you're in a tight NYC studio or an open-plan loft, the SuperFreq Subwoofer brings the physicality of live sound into your home—without the footprint.

FAQs
Why does your subwoofer look so different?
Because it is different. Most subwoofers use sealed or vented enclosures, relying on air spring and port tuning to extend bass. Ours is a quarter-wave resonator—a precisely calculated acoustic path that uses natural resonance to reinforce low frequencies. This lets us move more air with less distortion, producing deeper, cleaner bass from a smaller driver and enclosure. The result? Tight, musical low-end that integrates seamlessly with your speakers—no boom, no mud—just bass that feels like it’s part of the song, all from a slim, corner-friendly column.
How loud is it?
It’s 25W per channel—engineered for rich, full sound at apartment-friendly levels. We’ve tuned it for the widest frequency range and best dynamics at low to moderate volumes, so it sounds alive even when you’re not cranking it. That said, it’s surprisingly efficient—you can turn it up and easily fill a good-sized room. If you’re after club-level wall-shaking… let’s just say we might have something cooking.
How do I connect my phone to the speakers?
Our speakers ship with a Fosi BT30D amp featuring Bluetooth 5.0 for hi-fi wireless streaming. Just power on, open your phone’s Bluetooth settings, and pair with Fosi Audio BT30D. Done.
What’s in the box?
2x superFreq Speakers, 1x superFreq Subwoofer, Fosi BT30 Amp, and all the cables you’ll need.
Do I need cables?
Your speakers come with a set of three 8 foot speaker cables. Phono cables will be required if you plan to use wired connection to the amplifier.
Can I use a turntable?
Yes—but the BT30D takes line-in only. Check if your turntable has a built-in preamp, or you’ll need an external one.
What’s your warranty, return and repair policy?
We stand by our gear. Every SuperFreq system comes with a 12-month warranty against defects in materials or workmanship—if something’s not right, we’ll fix it or replace it. Changed your mind? You can return it within 30 days if it’s in original condition. And if life happens—spills, drops, party mishaps—we offer straightforward, reasonably-priced repairs to get you back to listening. Full details live on our Warranty & Returns page.
WHAT PEOPLE ARE SAYING
“THEY LOOK GREAT, AND SOUND INCREDIBLE AT ANY VOLUME. THE SUBWOOFER DESIGN MEANS YOU FEEL THE BASS IN THE MUSIC, NOT THROUGH THE FLOOR. IT'S CHANGED WHAT I LISTEN TO WHILE WORKING—I'M NOT AVOIDING BASS-HEAVY TRACKS ANYMORE JUST BECAUSE I DON'T WANT TO CRANK IT”
— Nathan Bracket - STEMS / Rolling Stone / Amazon Music
“IMPECCABLE CLARITY AND IMPRESSIVE DEPTH FROM SUCH A COMPACT SYSTEM. BRILLIANT ENGINEERING.”
— Joe Foxton - DJ / Creative Director / Audiophile
