Atlantis Lab SUBAT54: life on a grand scale

The SUBAT54 has been designed to equip demanding audiophiles as well as recording studios as well as for musicians on concert tours. Suffice to say that it has no limits in its capabilities or its performances. It stands out from all the competition with its high-efficiency 54 cm diameter speaker. Its internal volume is 250,000 cm3, or 250 liters, to exploit all the capacities of this masterful speaker and to allow the bass to express itself without processing. It thus descends to 18Hz with a colossal efficiency of 101dB, which makes it the ideal companion for any high-end speaker , whether it is Atlantis Lab brand or not. It is supplied with a built-in 500W amplifier - the S500 Atohm - with adjustable phase and cutoff frequency). For comparison, subwoofers from other manufacturers would have to exceed 10,000W of power to achieve similar performance (which is obviously not achievable). These monstrous characteristics allow it to find its place in any listening room, from large premises to intimate recording studios, including, of course, the living room of music lovers.

Muscle and style

The SUBAT54 is a subwoofer  that owes its success to its imposing dimensions. For this reason, it is manufactured to order and to the dimensions required by its owner. As long as the internal volume of 250 liters and the minimum width of 64 cm are respected, the dimensions can be defined as desired. For example, if you want a subwoofer with a height of 100 cm with the minimum width, the width will be 64 cm and the depth calculated at 51 cm. Aesthetically, the subwoofer incorporates the characteristics specific to the brand. The solid oak sides are beveled and grooved to eliminate parasitic resonances and make listening even cleaner and more transparent. The imitation leather covering is successful: the grain is visible but light, the tension is perfect, and the ash-brown or white colors are particularly timeless and pleasing. The two vents are located on the front. The whole thing rests on the proprietary Altantis Lab feet, consisting of four ball-mounted feet resting on a cup specially designed to optimize the bass response. The whole thing is very elegant, well-executed and a great success, able to blend into a wide variety of interiors.

Atlantis Lab SUBAT54: the absolute master of bass

There's no secret: bass requires volume to be deep, punchy, and powerful. Atlantis has taken this to its climax with its SUBAT54. It goes without saying that this subwoofer knows no bounds in the depth and power of the bass register. On live recordings that allow it, the listener will even be surprised to hear the subwoofers placed on stage. Its colossal performance does not leave aside its qualities of finesse and subtlety. The bass is clean, crisp, and precise. Its speed and articulation will allow it to accompany the best speakers, such as the Altantis Lab AT38 . Like any high-end subwoofer, it knows how to be forgotten during passages that do not include bass, while bringing its touch of listening comfort and substance. But it knows how to instantly reassert its presence when called upon, reaching peaks in depth and power; but always under control and mastery.
