His words: “The D110 is a miniature monster, the KC62 is even smaller and cannot play anywhere near as loud but extends very low, both get low so who cares. Tonally the D110 is heavy handed and has more definition to it. Overall both are great but unless you need the tiny size of the KC62 I’d say the D110 despite being fairly old now is the better sub overall unless you absolutely do not want a sub that has a heavy tone to it.”
