18 HERTZ AND NO END OF ACOUSTIC PRESSURE CERTIFIED BY THX®

Solid, dynamic bass for home cinemas up to 18 Hz

Smallest THX Ultra 2-certified single subwoofer in the world

32 cm high-performance woofer supported by two 32 cm passive membranes

Integrated Class D amplifier with 550 watts RMS and 1,100 watts of maximum power output

Extremely sturdy MDF cabinet with solid 45 mm baffle

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
