Markbass MB58R 104 Pure Box 8

I’ve been dreaming of my setup with Markbasses since early 2025, and after two weeks of real-world testing, I’m still in shock.
I’m running two of these Markbass MB58R 104 Pure (8 ohm versions) in a stack, powered by my Eich T1000. The result is a massive 8x10 wall of sound that delivers incredible presence and power, yet I can carry each cabinet with one hand. This is a game-changer for both my tone and my back.
The flexibility of this "twin" setup is perfect. Depending on the venue or stage size, I can take just one cab for a compact high-power rig or stack both for a luxury tower that commands the room. Each cab handles 800W RMS, which gives me massive headroom. Even with my 1000W head, I never feel the speakers are struggling; they just deliver clean, punchy low-end with zero distortion.
The "Pure" series hi-fi tweeter is a standout feature. It’s remarkably clear and precise, giving the bass a high-fidelity definition that highlights the transparency and "zinggg" of new strings. It’s not that "harsh" clicky sound you find in cheaper horns; it’s a smooth, professional high-end that makes every harmonic shine, i adjusted the tweeter level switches on the back to -6dB on the top cab and -15dB on the bottom cab and it sounds perfectly balanced to my ears.
In my opinion, the build-to-weight-to-price ratio is extraordinary. Markbass managed to use this new light-weight materials to create a resonant box that feels solid but weighs next to nothing. The low-end is tight and fast and it captures the velvet of the woods and the resonance of my bass hardware perfectly.
To be quite honest, the global sound of them is way better than i was expecting. I was opened to have some compromise because of having a cab so much lighter than traditional wood cabs, i was expecting to have some level of "plastic nasal" tone in it, or some rattling when pushed to the limit, but no, not at all! The cab is strong and with top notch design, they deliver all of the amp's sound clear and defined at Hi-Fi level with full power. They can make your nose bleed and your chest smashed with the punch.
Even more if you stack them like i did to create a "monolith" that delivers the sound right to my ears and body, but without the nightmare of transporting a 80kg traditional 8x10. If you are looking for a professional sound, is easy to transport but capable of shaking the stage with authority and at a reasonable price, this is the ultimate solution.

Marco and his team at Markbass have done it again. I upgraded from the previous model, and the weight different is staggering. You can literally lift this with 2 fingers and throw it around like a beach ball. It's amazing, and makes getting in and out of gigs so easy.

The new Hi-Fi Tweeter (I think designed with Marcus Miller) is so transparent. For slap/popping it's unbelievably tight - but if you use effects like overdrive, or chorus it shines so bright. And if you want a more motown feel you can switch it down, or off completely so you get the best of all worlds.

Amazing cab up to the usual high Markbass standards!

This cab is very light and made out of interesting material. Kinda foam-eesh. But it sounds great and compact. Another great option is that you can turn on and off tweeter driver and also trim some db by -9db. -6db and -15db. You can also stack 2 of them for 8X10 @4ohm with the other MB58R 104 Pure box 8 or 104 Energy Box 8, turn off the tweeter on one of them, or adjust the way you like it on both. Perfect!
