The24 SUB PRO PASSIVE SEALED infrasub is a statement.
Its huge cone surface area and huge 90 mm of linear stroke - represents a world record for cinema subwoofers - allow it to move a gigantic volume of 10 liters of air per stroke to pressurize the room. Due to its ultra-low resonance frequency and its sealed enclosure design the group delay is several times faster than the smaller 18", 15" or 12" subwoofers at the same frequency. Also the acoustic power output per cubic inch is by far in favour of this unique design compared to stacked multiple smaller subwoofers.
Its ingenious design allows the The24 SUB PRO to produce frequencies in the infrasonic frequency range with authority, reaching down lower than subwoofers with a smaller diaphragm surface ever will. At the same time this infrasub renders those notes with much more power, structure and resolution.
The The24 SUB PRO ideally suits not only all types and sizes of cinemas, but also high-end stereo systems. Much of the spacial room information of the recording envirnment in a great audiophile recording is contained in the sub 30Hz audio band. You will hear more details in mid and high frequencies.
