18 hertz and no end of acoustic pressure Certified by THX®
The Cinema Ultra Sub 300-THX subwoofer also amazed the THX engineers: It is the smallest woofer so far to have been awarded THX Ultra2™ certification. Here, too, the basis for the record is the very latest technology. The 32 cm high-performance driver is optimised for a large stroke and minimal distortions. For power right from the bottom – the Cinema Ultra Sub 300-THX goes all the way down to 18 Hertz! – the subwoofer is supported by two passive radiators of the same size and appearance. Together with the newly developed 550 watt Class D power amp, they are located in a compact, extremely sturdy enclosure where the baffle alone, made of 45 mm thick MDF, effectively suppresses a lot of vibrations.
