A few days ago the CEDIA Expo 2021 fair was held, an event in which different news regarding sound equipment have been announced, such as speakers, amplifiers, receivers, sound bars and subwoofers.
But none as surprising at first glance as the one that the company has run Ascendo Immersive Audio and who they have baptized as Ascendo Active Seismic SMSG50, a giant, enormous beast, with a driver diameter of no less than 50 inch that promises completely thunderous subwoofers.
To get an idea of the specs of this behemoth, its sealed-type loudspeaker has dimensions of 1800 x 1850 x 600mm weighing more than 400 kilos and is specialized in the reproduction of frequencies in the 5 Hz to 20 Hz range, that is to say in the subsonic strip.
These are frequencies that we perceive with the whole body and not only with the ears, requiring titanic woofer diameters as in this case if we want to achieve levels of SPL or sound pressure elevated.
In this case, your driver 50 inches or 127 cm in diameter promises to be able to reach the 136 dB in continuous playback with spikes of 140 dB (125 dB at 20 Hz) using a built-in amplification stage of no less than 6,000 watts.
Of course, it is not an equipment that we can put in a conventional home, since to begin with, many of us may not have the electrical connection required as to feed this giant nor the ground that resists its weight. Furthermore, such peak sound pressure levels are clearly harmful to hearing health.
Is a team of such proportions necessary to enjoy your favorite movie? Well clearly not. For most mortals with one or two subwoofers up to 10-12 inches it is more than enough if we do not want to be kicked out of our neighborhood communities and urbanizations. But yes, we must admit that the Ascendo speaker is really spectacular.
Price and availability
Of course, in the demo they did not give sale prices, but probably whoever has a room where to put such equipment will not be short of financial resources.
