1. A loudspeaker system comprising:
a left transducer;
a middle transducer, wherein the left transducer is offset from the middle transducer in a left direction substantially perpendicular to a longitudinal axis of the middle transducer;
a right transducer, wherein the right transducer is offset from the middle transducer in a right direction substantially opposite the left direction;
signal processing electronics configured to:
receive a left audio signal;
receive a right audio signal;
generate a left crosstalk cancelation signal, the left crosstalk cancelation signal comprising an inverted instance of the left audio signal;
generate a right crosstalk cancelation signal, the right crosstalk cancelation signal comprising an inverted instance of the right audio signal;
drive the left transducer based at least in part on the right crosstalk cancelation signal;
drive the middle transducer based at least in part on the left audio signal and the right audio signal at frequencies above about 600 Hz; and
drive the right transducer based at least in part on the left crosstalk cancelation signal.
