Earthquake Sound IQ-600R amplifier

The IQ Amps offer a room correction technique that surpasses that of all previous attempts. The intelligent “Back emf” drive circuit interacts with the subwoofer design and memorizes system tuning frequencies and system type. The information which is stored in the microprocessor turns on a preset group delay curve that serves as a correction reference. This information deals only with time correction that moves the peaks and the dips in a room a flat. Once that is achieved the user will resort to the final correction- EQ the room. For that reason Earthquake’s IQ Amps are truly intelligent systems. 20Hz, 30Hz and 40Hz frequencies can be cut or boosted by a whopping 6dB, these corrections help in producing wider range of listening position that is unprecedented for the room.
