I never buy something because of the brand, because I know that it usually isn't value for money. After several comparisons I saw on YouTube, I decided to take a risk with this product.

Aesthetics. Definitely, when we look at Marshall speakers, aesthetics matter to us, regardless of the style we have. From the moment someone thinks about filling their home with music, but also gives importance to visual aesthetics, then this is definitely a speaker that can meet their needs. Whether you have a vintage, rock, alternative, Swedish, minimal, or Bauhaus aesthetic in your home, this speaker can match and sometimes highlight a corner of the house, whether it's next to a plant, books, or even just on the floor.

Sound. It's definitely not high fidelity since it uses a class D amplifier (which I don't understand why class A wasn't chosen since it's not portable), but it is at least capable of playing all genres of music. With lows below 30hz, it can even play house, trap, club, and electronic music very satisfactorily, even at high volumes. If you want it for a party, it's better to bring another identical one and pair them, and you'll definitely be okay, but even on its own, it can handle it. With the EQ of the app, you can adjust the sound as you like, which is rare to find.

With RCA, you can connect a better Bluetooth receiver or even a line signal from another source for better sound.

Overall. If someone prioritizes sound quality, they will definitely consider the Harman Kardon Onyx Studio 6, especially for its minimal design. If someone doesn't care about appearance, they definitely won't be looking at Bluetooth speakers. However, if you want to combine very good sound with a very good appearance, then I think you have the balance you want here.

Excellent sound, powerful, full, and with rich bass. The capabilities of a wifi speaker like this one are much greater compared to those of a bluetooth speaker. It's very convenient that there are presets with which you can play your favorite playlist or the station you want by simply pressing a button. I mainly use it as an internet radio and for playback via Google Play Music. I have also tried it with AirPlay from an Apple device. I don't have a second device, so I can't express an opinion on the multiroom function. However, I am very satisfied, so I plan to get a second one. The app is okay; it could be better.
