Room Correction IQ Subwoofer Power Amplifier The IQ1500 offers 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 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 to a flat.
