I Take These Plug-and-Play Modular Speakers Everywhere

Doing a quick search for Bluetooth speakers online gets me dozens upon dozens of options, which quickly becomes pretty overwhelming, even though I review these products for CNET. There are the more popular Bluetooth speaker options, and the safe buys, like the JBL Charge 6 and the Soundcore Boom 2 by Anker, both of which I’ve personally used. But each Bluetooth speaker serves a different purpose so if I’m buying a new speaker, I need to think about what I want out of it.

What I’m looking for is a versatile speaker. One that’s portable but sounds high-quality. One that I can use at home and in the office or toss up at a backyard party. That’s where Rocksteady’s Stadium 2.0 speakers come in. I can connect an unlimited number of high-quality speakers with the Stadium, including a wireless sub-woofer, for any summer activity I have going on. They’re wireless, portable and have up to 30 hours of battery.

A Bluetooth speaker that can morph from travel companion to full-blown party setup

Rocksteady’s Stadium 2.0 kits all strive to do what most other Bluetooth speakers can’t easily do: scale from a single bedside speaker to a backyard surround sound rig, all without the tangle of cables, and still provide high-quality sound.

You can go with a single speaker ($150), which offers a dual-driver setup (powered tweeter and mid-bass driver) along with dual bass drums, so you get crisp highs, warm mids and some of that low-end thump. I use a single speaker in my bedroom or office, where it’s a relatively confined space, where I don’t need too much.

If you want to upgrade your listening experience to something punchier, you can add a dedicated subwoofer ($180) to your speaker. You obviously get more bass, and you notice the difference if you’re listening to hip-hop or EDM, or watching a movie with lots of gunfire and explosions. If you want to go this route, I would definitely recommend the speaker and subwoofer pack ($400), which comes with two speakers and a sub.

But where the Rocksteady Stadium 2.0 excels is in the four-speaker and subwoofer pack. Yeah, it is a little expensive at $600, but if you have the money, it offers the most versatility because you can connect as few or as many speakers as you need for whatever occasion. This is the setup I use the most for everything from backyard barbecues and parties at Airbnbs to listening parties and movie nights.

Setting up all your speakers is as easy as a tap of a button

Getting the Stadium 2.0 up and running is pretty simple. You can power on any speaker and then hit the Bluetooth icon to pair it to your phone — you should see a unique “Rocksteady_XXXX” ID.

That first speaker will become the host. After that, simply hit the Stadium button on the host and then on each extra satellite speaker, or wireless sub, to add it to the mesh. It takes about 15 seconds to pair all of the speakers into one, and the best thing about it is that your speakers remember this lineup, so the next time you turn them on, they’ll all automatically connect, without you having to re-pair them.

Once you’re all linked up, you can assign each speaker with a left, right or stereo duty designation with a quick toggle, letting you build a two-channel desktop rig for your computer or a bunch of dual-duty speakers for surround-sound in your backyard.

The system keeps all channels in sync up to roughly 150 feet, and each box charges over USB-C, so grabbing any phone brick will top them off for the quoted 30-hour run time. And the four-speaker kit comes with a carrying case, so it’s easy to travel with all your speakers.

In short: no app, no cables, no headache — just place, pair and press play.
