The Quad S-1 and the Sonus Faber Lumina I stand at nearly the same height, around 28.5 cm tall. The Quad S-1 reaches deeper in the bass, down to 58 Hz versus 65 Hz. Low frequencies come from a 100 mm cone on the Quad S-1 and a 120 mm cone on the Sonus Faber Lumina I. On price, the Sonus Faber Lumina I sits higher — about $999 a pair against $799 for the Quad S-1.
