At 90 dB against 88 dB, the Castle Knight 2 is the easier load to drive and plays louder from the same amplifier. The Castle Knight 2 reaches deeper in the bass, down to 42 Hz versus 46 Hz. Low frequencies come from a 150 mm cone on the Castle Knight 2 and a 165 mm cone on the Q Acoustics 3030i. Both land in a similar price bracket, around $505 a pair.
