Harman Kardon Onyx Studio 6

Harman Kardon Onyx Studio 6

Harman Kardon is one of the oldest companies that produce high-quality audio products. They’ve started back in the early 50s and move their way up to be one of the respected audio companies in the world.

They are widely known for creating unique designs for speakers where perfection is not enough. Additionally, they also supply audio equipment for big car manufacturers such as Audi, Mercedes-Benz, BMW, and many more. So, now you know that we are talking about a serious audio manufacturer.

Design

Design

Their latest Bluetooth speaker Onyx Studio 6, features a unique but elegant design, which will definitely look good in your home. It is made from high-quality materials like fabric finish and aluminum. To accent its portability, it has a handle on top of the speaker so you can easily carry it around anywhere you go.

It has five buttons (power button, volume up and down, Bluetooth, and Sync) on the front that are hardly noticeable and blend in very nicely with the design.

It is probably one of the most refined Bluetooth speakers available on the market. The Onyx comes in three colors black with a black handle, and navy blue and gray with sleek looking bronze handle.

Just like most Bluetooth speakers, it is rated for IPX7 water-resistance, which technically means that you can submerge in water up to 1 meter for 30 minutes.

Specifications

The Onyx Studio 6 has one 120mm woofer and one 25mm tweeter, which means that it can deliver a compelling sound. Its frequency response is from 50Hz - 20kHz, which is plenty enough to fill the whole room or outdoor area with your favorite music.

In terms of sound quality, the Onyx Studio 6 will outperform most Bluetooth speakers. There is absolutely no distortion even when you pump up the volume to the max. Even though it has only one tweeter, it can still produce sharp, high pitched sounds.

Despite its large dimensions, it only uses a 3,283mAh Lithium-ion battery that is capable of playing music for up to 8 hours, depending on the volume and music content. However, from our experience, you will extend that limit since it is a very powerful Bluetooth speaker, and you will only be listening to music at 60%.

When it comes to the design, almost all JBL series look identical. The only difference is the size. That is the case with the JBL Xtreme 2, which has a cylindrical shape.

To accent the portability of this speaker, JBL decided to add straps that come with the speaker so that you can carry it around wherever you go. Since it is a bulky speaker, it is not designed for day trips or taking it on a plane.

Just like most JBL Bluetooth speakers, it is very durable and made with hit resisting materials that can withstand quite a few bumps. The Xtreme 2 is covered in rubber, which is a great way to protect the speaker.

Additionally, it has IPX7 water-resistant certification, which means it can be submerged in water up to 1 meter for 30 minutes.

The design isn’t actually revolutionary. It is something that is already seen from previous JBL models. The Xtreme 2 comes in three color options to choose from, black, forest green, or dark blue.

Which is better JBL Xtreme 2 or Harman Kardon Onyx Studio 6


It is time to put both Bluetooth speaker to the test by comparing some of the features on both devices.

Sound Quality

Sound Quality

Both devices are compelling and can provide enough sound for every occasion. However, they have a different way of delivering that sound.

Xtreme 2 is more powerful and can provide a louder bass kick since it has passive bass radiators. On the other hand, the Onyx Studio 6 has a lower frequency range, which means it can capture deeper sounds better. However, if you play the Onyx Studio 6 at high volume, the Bass is slightly reduced, making the Xtreme 2 a better option.

When it comes to highs and mids, the Onyx Studio 6 has a perfect balance. It delivers more natural sound even compared to speakers from a higher division. It’s rival the Xtreme 2 also has balanced mids and highs, but with the high kick from the Bass, sometimes it is hard to accent the vocals.

If louder sound and deeper kick is not something you are looking for, and you want a Bluetooth speaker that will accent your living room, the Onyx Studio 6 is a perfect choice.

Winner: JBL Xtreme 2

The Onyx only has 3,283mAh Lithium-ion, which gives it up to 8 hours of playtime, whereas the JBL Xtreme 2 has a massive 10,000mAh capable of playtime up to 15 hours. Both devices can outplay the time stated by their manufacturers if played on a lower volume.
