The Kiwi Ears Quartet was designed around our new isobaric double dynamic driver subwoofer. The innovative driver design utilizes double 10mm titanium diaphragms drivers, each independently driven by dual magnetic circuits. The pair of drivers were passively aligned to be phase synced and prevent soundwave cancellation. This new subwoofer design emits extremely well extended sub-bass kicks that are tighter, faster, and deeper than any other previous woofer designs. The Quartet is Kiwi Ear's answer for all those who want a fun in-ear monitor that will provide all the quality bass one could need.
