What That Means in Real Use

• Deep bass reach: Being able to reproduce low frequencies down near ~9‑10 Hz (full range) means it can deliver sub‑bass effects in movies or music that you feel (not just hear).

• High output with clarity: With large RMS power and a robust driver + motor, peaks are handled with authority and distortion is kept very low.

• Fine control & tuning: With adjustable crossovers, phase, polarity, and a powerful DSP room calibration (Auto‑EQ Plus), users can tune the sub to match their room and main speakers.

• Large rooms or demanding use: Due to its size and weight, this model is best for larger listening rooms, home theaters, or spaces where strong, accurate bass is needed with minimal compromise.
