Quantum Drive – The Art of Silent Rotation
Large pulleys. Deep silence. Living music.
In conventional turntables, the drive system often betrays itself with a fine, nervous veil – especially in the spaces between the notes. We have torn that veil away.
Our answer: the 168 mm giant pulley – the very heart of Quantum Drive.
1. Motor Frequencies Far Below the Audible Range
Platter speeds: 33⅓ rpm → 0.55 Hz | 45 rpm → 0.75 Hz
Typical 15 mm pulley: motor spins at ~11.1 Hz (33⅓) to 15 Hz (45)
→ Motor harmonics & resonances fall squarely in the audible band (22 Hz – 120 Hz+): subtle unrest, nervousness, coloration
Quantum 168 mm pulley: motor runs at only ~1/10th the speed
→ Disturbing frequencies are shifted down into the single-digit Hz range and below
→ Result: pitch-black background, relaxed naturalness, music that breathes freely
