Introduction

A team of scientists from the University of Lisbon have discovered gravitational waves in space, which were formed as a result of the collision of black holes. It was this collision, according to the researchers, that could lead to the emergence of a new object – the gravastar.

“Gravitational vacuum star” is an acronym and translation of the term GravaStar, which, in turn, means a hypothetical object larger than the solar system, consisting of dark energy.

This is the unusual name of the company that launched Indigogo crowdfunding with the GravaSrar Mars device. And later, when the necessary money was collected, the Mars Pro model appeared.

What is it? Mars Pro is an all-zinc-alloy portable robot crab speaker with passive radiator and dual woofer and tweeter speakers. The device is quite large, heavy, made with the highest quality and presentable. Such things will appeal to connoisseurs of near-space themes or collectors who collect different models of original robots. The GravaStar Mars Pro will impress any person who sees the acoustics of this kind for the first time. The device can simply be a piece of furniture even without a sound transmission function.

When I got the Mars Pro for review, it seemed to me that such a device, judging by its appearance, should cost unrealistic money. However, only 19,990 rubles will be asked for this model. Sales in Russia will start shortly.

Design

The appearance of the GravaStar Mars Pro is what this device will be bought for, since you will not surprise anyone today with a portable speaker in the classical sense.

The first impression of the device: “Wow!” It is a Sci-fi robot crab with a round body made of zinc alloy, weighing 2.5 kg. Yeah, this is not a “china basement” made of flimsy plastic, which strives to fall apart in the hands of the owner!

Overall dimensions – 190 × 180 × 200 mm. Not too small, but not big enough to fit anywhere on your desktop.

The “muzzle of the face” is made of plastic, the expression is semi-aggressive due to the convergence of two decorative inserts descending from top to bottom. Behind these elements is a metal mesh. It carries a 1-inch dome tweeter.

Right and left on the front of the “robot” there is something like a radiator grille. They have 5 LEDs built in each.

Large screws are visible on the right and left side edges. There is also a poorly discernible large inscription MARS Pro.

On the “head” of the acoustics, the developers installed a touch-sensitive volume control panel, indicated by strips with LED glow. The fewer bars you see, the lower the volume.

On the reverse side, on top of three projections, there are mechanical buttons:

  • Color management. Two clicks – switch the backlight to red or return to a smooth transition between different colors. A long press turns off the backlight on the “claws”.
  • Nutrition. Turns the device on or off. A short press stops the music, a second press restarts it.
  • Bluetooth connection.

On the back of the “robot” you can see a large 65 mm passive radiator, which “shakes” when reproducing low frequencies. And on the silver-colored cover of the emitter flaunts the GravaStar logo in the Gothic style.

On the right and bottom left there is an inscription Designed by ZOEAO. It seems that Zoeao is a startup developer, and GravaStar is their brand.

This whole round structure is mounted on three “claws”. They are also made of zinc alloy. Heavy, tough, powerful. Moreover, they are initially in a folded state, and to be placed on a flat surface, the “claws” must be straightened out.

To avoid scratching the surface on which the speaker will be installed, there are rubber inserts at the ends of the legs. Purely visually, the design looks like the claws dig into the surface. In the inner area of ​​the legs there are also rubber inserts. They are necessary to prevent abrasion of the inside of the leg when folding the “claws”.

Device one hundredandt smoothly, confidently, does not stagger, despite the weight of about 2.5 kg, even when playing music at maximum volume.

About sound

It seems to me that in this case talking about sound is not as interesting as writing about appearance. After all, for 20,000 rubles you can buy portable acoustics for almost any color and taste. However, the GravaStar Mars Pro plays extremely well for its positioning.

Inside is a 64mm woofer, 25mm tweeter and 66mm passive radiator. The peak power of the acoustics is about 20 W. Based on the spec, a tri-band crossover is used here. In this case, the frequency range is not indicated. To my ear, this is from 40 Hz to 15,000 Hz.

  1. Volume… In the absence of an abundance of bass, the volume is quite high – a room of 20 m2 pumps. As soon as low frequencies appear, the volume is reduced by one and a half times. But, in general, it is enough for a small room.
  2. Innings… Slightly below average.
  3. Volume… It is rather weak as only one channel is used.
  4. Voice… Sounds very clear, sonorous, without distortion. Both male and female parts sound pleasant.

It is better to listen to melodies on this speaker, which do not have sharp inclusions of low and high frequencies. The priority is popular music, classical, partly soul, you can try jazz or even rock. Rap is a little weaker due to the mixing of lows and highs.

Working hours

Battery capacity is not indicated. In my conditions, the device worked at a volume of 20-50% for about 10 hours. If you listen to music at the volume level in the background, then 15 hours will be enough.

It is charged via USB Type-C, which is located at the bottom of the “robot”. For Mars Pro and other models, there is also a special docking station that resembles a spaceport.

Impressions

It seems to me that there should be some emotions from GravaStar Mars Pro. Even if the device was not a portable acoustics, then for its cost it would look great on a desktop in the office of a gamer or a person who appreciates designer gizmos in the form of robots. An excellent accessory, a good speaker, a super-duper gift for all occasions. I myself would love to use Mars Pro as an attribute when shooting photos and videos.

From the point of view of the quality of acoustics, everything is simple: the low frequencies are powerful, the high frequencies are present, the voice transmits perfectly. By the way, if you buy one more speaker, it will be stereo.

As such, there are no drawbacks, but I would make the backlight a little more “smart”, that is, somehow I would have played up the theme of space. And something like “Gravastar / Mars” (!), But just smoothly blinking LEDs.

I saw a similar device in the Vipe – the Stryder model. It costs about 8,000 rubles. It is much simpler than GravaStar: it weighs only 1 kg and lasts up to 6 hours, and the material is plastic, not metal. I did not notice any more analogues in our market. Most likely, Vipe spied on GravaStar. For too similar design.

Total: GravaStar Mars Pro is a great device for sci-fi connoisseurs, I recommend it!

Soon in Russia the Mars Pro model can be found for 20,000 rubles.
