Are these the best PC speakers? SteelSeries Arena 9 discounted by 4 thousand

There aren’t that many full-fledged 5.1 speakers designed for computers on the market – most gaming sets stop at 2.1. SteelSeries Arena 9 have now dropped to 12,187 CZK after entering code ALZADNY25, which is significantly below the current price of 16,249 CZK and even below the original 13,990 CZK for which the set was previously sold.

Quick summary:
✅ Makes sense if you want full-fledged surround sound for games and movies on your PC.
⚠️ Consider if you have a small room or live in an apartment building – the 6.5″ subwoofer can really rumble.
💡 For 12,187 CZK, this is one of the few 5.1 setups with USB connectivity and wireless connection for the rear speakers.

What you get in the package

The setup is a complete 5.1 – meaning two front satellites, two rear ones, a center speaker, and an active subwoofer with a 6.5″ bass driver. A hit that SteelSeries made with this series is the wireless connection of the rear satellites via Bluetooth. In practice, this means you don’t have to run cables across the entire room to the rear speakers; you just power them from an outlet. For a computer set that often ends up in a regularly furnished room, this is a crucial difference.

The system connects to the computer via a single USB cable, eliminating the need to combine green, orange, and black 3.5mm plugs, as was common with older 5.1 speakers. Additionally, there’s an optical input and a 3.5mm jack for a phone, tablet, or TV – so you can use Arena 9 as desktop audio even beyond your PC.

OLED controller and Sonar software

One of the things that distinguishes Arena 9 from cheaper competitors is the wired control module with an OLED display. You can directly adjust volume, pair Bluetooth devices, switch sound profiles, or change RGB backlighting on it right on your desk – without reaching for your mouse and opening an application. More detailed tuning is handled by the SteelSeries Sonar software, which offers a 10-band parametric equalizer, spatial effects, and virtual scene switching.

The specifications mention a frequency range of 35 Hz to 20 kHz, so the bass will go really deep. This is also confirmed by owner reviews – one of them on Alza directly writes that the bass might rumble too much. If you live in an apartment building with neighbors below you, remember that with this set, you’ll reach for the subwoofer’s volume control more often than with typical 2.1 speakers.

Who it makes sense for and when it doesn’t

Arena 9 targets players of shooters, racing games, and simulators, where spatial information “where the sound is coming from” has real in-game significance. It’s also a good choice for movie fans without space for a soundbar plus rear speakers – this setup is essentially a small home theater on a desk.

Conversely, if you mainly listen to music or do production, you’ll do better with a pair of stereo monitors. And in a smaller room, where you sit half a meter from the display, the spatial effect of the rear speakers will be lost anyway. A slight note also deserves the higher reported return rate of 10%, which Alza states on the product page – when buying, it’s worth thoroughly testing everything right after unboxing.

Is stereo enough for your computer, or do you prefer full-fledged surround sound?
