Small, portable Bluetooth speakers can sound really good, but let's be honest: if you're soundtracking a large gathering or party, a small one isn't going to cut it. You need a proper party speaker for that, one that gets incredibly loud and makes your guests feel like they're at a concert. How about one that hits a staggering 121dB, then?
The Soundboks Mix is perhaps the loudest speaker I've tested yet. It's loud, but even at the highest volume, music doesn't sound too distorted, and the treble and mids remain surprisingly clear. Bass is nothing short of Earth-shaking, and the room-filling sound leaves you drooling. But...
Yeah, there's always a "but." It's part and parcel of testing and reviewing products, because few (if any) are perfect. The Mix is no different. Even though I love its sound profile, its drawbacks have left me feeling shortchanged — and when $799 is on the line, you want bang for your buck. There is one speaker out there that's great value for money, and sadly, it ain't the Mix.
Shake the ground
One of the Soundboks Mix's biggest selling points is that it's get ridiculously loud. At a whopping 121dB, the Mix sounds loud enough to vibrate a glass off a desk if you're indoors, or shake the ground when you're outdoors. Metaphorically speaking, of course — I didn't actually manage to drop a glass off a countertop.
All that's to say is that you can certainly be the life of the party with the Mix. Whether you're head-banging to bass-heavy rock or dancing to electronic dance music, the Mix has you covered. Two 72W Class D amplifiers powered by a 10-inch woofer and a 1.2-inch dome tweeter cover a frequency response range of 40Hz to 20KHz — typical for a speaker of its demeanour.
Regardless of the tune I listened to, I was impressed. Lana Del Rey's vocals in ‘First Light’ sat front and centre and sounded remarkably clear. The warmth, texture and emotional nuance were reproduced accurately, while subtle details in her delivery found themselves in the spotlight without sounding too clinical. The treble in rock tunes, like ‘Elma’ by Yin Yin and ‘Echoes’ by Pink Floyd, shone and sounded vibrant without cutting through the rest of the soundstage.
Hear me out...
Naturally, I have a lot more to say about the sound quality, which is why my in-depth review is there! Check out my Soundboks Mix review for all the details.
None of that would matter, however, if the Mix didn't do what a party speaker is designed to do: make you dance to electronic tracks, and it manages to do so. The bass in ‘Lights Burn Dimmer’ by Fred Again and Jaime T sounded controlled and tight with the EQ set to Indoor. It didn't overpower the rest of the soundstage. Switching the EQ preset to Bass+ made me feel the song in my bones. It was loud and made the ground beneath me shake. I could feel my teeth chattering.
Turning the volume all the way up to 10 (as you might do if you're hosting a party outdoors) revealed a weakness, though. The bass was still room-filling, but it sounded wobbly and uncontrolled, like the Mix was struggling to keep up with it, or was feeling overwhelmed by it. Truth be told, that's not great news for a party speaker — especially for one that costs just under $800... which, very nicely, brings me to my next point.
Nowhere to hide when the competition is so good
When I was testing the Soundboks Mix, I couldn't help but think to myself, "This speaker could be the best party speaker around... if it wasn't competing with the Marshall Bromley 450." The Bromley 450, Marshall's second-ever party speaker, is a top-notch product that doesn't skimp on features on sound quality. I've thoroughly tested that speaker too, and knowing what it offers for the same money has further highlighted the Mix's flaws to me.
One of the first things I noticed about the Mix was its lack of ports. All you get is a USB-C port for charging and a 3.5mm jack for wired playback. The Bromley 450 goes above and beyond here, with two XLR/6.35mm combo ports for microphones and acoustic/electric guitars, and RCA ports for keyboards and turntables. It essentially doubles (or triples) as an amplifier and a karaoke machine.
You've then got the Mix using an old version of Bluetooth: 4.2. That's not bad, per se, but it isn't good either for a speaker that came out in March 2026. Bluetooth 4.2 is an old version at this point. That means shorter range and no way to stream LE or hi-res audio, so you're stuck with the basic SBC codec.
The Bromley 450 has yet another ace up its sleeve: 360° True Stereophonic surround sound, which means that regardless of where you're standing in a room, you'll hear the same exceptional sound. This makes listening to your favorite tunes more immersive, something the Mix can't achieve.
Combine all of this with the wobbly bass and you've got yourself a clear winner. The Mix costs $799 / £599, and the Bromley 450 retails for $799 / £549, and for the same price, you get versatile connectivity options, better Bluetooth and LE audio, 360° sound, and even integrated stage lights that react to the music.
