The most immersive gaming speaker system I’ve ever tested is almost 30% off at Amazon

The subwoofer also acts as the main connection point for audio output via USB, Bluetooth, or optical cable — you can use the subwoofer as an optical passthrough for theoretically connecting third-party soundbars or speakers if you already have something you’re using to boost dialogue or ambient sound. While you can set up all three connection types at once, you can only use one physical connection at a time, along with the Bluetooth-connected device. And the Bluetooth source will mix with the physical one, allowing you to catch PC or console notifications while using another device or stream music, movies, and shows.

I connected the Arena 9–> to my PS5 via USB and used Bluetooth to connect to my iPhone 13 and desktop PC. While you’ll get an excellent dialogue and hi-tone boost straight out of the box, you do have to take some time to tweak settings, either via the OLED controller or Sonar desktop app, to get the best tones and volume levels for each set of speakers. The rear speakers like to be very quiet and flat-sounding at first, but switching to the Excite or Bass Boost EQ preset on the OLED controller immediately improved the surround sound effect and overall quality.

The OLED dial gives you a good amount of flexibility and control when selecting EQ presets or making manual adjustments, especially if you’re connected to a non-PC device like a cell phone. You can toggle the 5.1CH Upmix on and off, which disables the rear speakers for more focused audio, though it does sound much more flat and uninteresting than when enabled. SteelSeries has introduced a brand-new streamer mode for the app, which allows you to separate your programs into different output streams for unprecedented control over your audio.

You can set programs to be recognized as games, media, or chat and customize the output mix to favor one or another. This was a godsend when organizing Discord movie nights with friends, allowing me to boost the film’s audio over the voice chat, so I didn’t miss any important plot or dialogue. And if you want even more in-depth customization options, each media type has its own EQ tab within the app, letting you choose different presets from what you find on the OLED controller or tweak frequencies to suit your space and preferences. You can even toggle spatial audio on and off, which is great for switching between games where you need to be able to pinpoint audio cues and movies where you may not want the audio to feel like it’s coming from different places.

I spent several days working my way through a New Game+ run of Gotham Knights–>’ Heroic Assault mode on my PS5 while also bingeing The Real Housewives of Orange County<!–> on my dual-purpose work/gaming desktop. Not only did the Arena 9 handle both connections beautifully, but it was also easy enough to tweak settings within the Sonar app to balance the two, so I didn’t get overwhelmed with arguments about not getting invited to a party while I was trying to escort a laser cannon through a mob.

The speaker system is also excellent for streaming music; I played the Old Gods of Asgard album Rebirth while doing photography for upcoming reviews, and the original 13-minute cut of “Herald of Darkness” is a borderline religious experience with the right EQ tweaks. 

My one big complaint about the SteelSeries Arena 9 is that you really do feel that drop in control when dealing with a device that’s been connected via USB or optical cable. The OLED dial allows you to choose between a few different presets but only offers a single option for a custom sound profile. In contrast, the Sonar app lets you create a custom soundscape for every media type and connected device.  

ZDNET’s buying advice

There is a lot that comes with the SteelSeries Arena 9–>, between the speakers and subwoofer, controller, and cables. It’s easily one of the best-sounding systems I’ve tested, and the ability to tweak specific audio settings is game-changing. That said, if you mainly use a single platform like the PC or a console for gaming, you may want to opt for the smaller but still capable Arena 7<!–> instead, since it comes with a single pair of speakers and a subwoofer. It doesn’t include a control dial like the Arena 9, but you can quickly adjust basic volume and bass boost levels with the on-device knobs for watching shows and movies. 

And if you’re simply looking for a reliable set of PC speakers, the Arena 3–> is an excellent choice; they don’t have the RGB lighting features like the Arena 7 and 9, making them a better choice for shared work spaces or home offices that double as gaming rooms. If you’ve been waiting for a decent deal to come along before you pick up the Arena 9, Best Buy<!–> is running a sale where the speaker system is $100 off its original price; this brings it down to $450, and while that’s still on the pricey side, the multimedia support, ability to connect to multiple devices simultaneously, and incredible sound quality make it a worthy investment for your gaming space or home theater.
