1. A wearable head device comprising:
a left woofer component including a left woofer sound outlet;
a left tweeter component including a left tweeter sound outlet;
a left support structure configured to provide mechanical support for the left woofer component and the left tweeter component such that the left woofer sound outlet is spaced from the left tweeter sound outlet by at least ½ centimeters;
a right woofer component including a right woofer sound outlet;
a right tweeter component including a right tweeter sound outlet; and
a right support structure configured to provide mechanical support for the right woofer component and the right tweeter component such that the right woofer sound outlet is spaced from the right tweeter sound outlet by at least ½ centimeters;
an input configured to receive an audio signal;
a left woofer output coupled to the left woofer component;
a left tweeter output coupled to the left tweeter component;
a right woofer output coupled to the right woofer component;
a right tweeter output coupled to the right tweeter component;
a left audio signal filter coupled to the input and drivingly coupled to the left woofer component through the left woofer output, the left audio signal filter configured to apply a first gain to at least a first frequency band in a first frequency range extending from 20 Hz to 100 Hz and further configured to apply a second gain to at least a second frequency band in a second frequency range that extends from 100 Hz, wherein the first gain substantially exceeds the second gain;
a right audio signal filter coupled to the input and drivingly coupled to the right woofer component through the right woofer output, the right audio signal filter configured to apply the first gain to at least the first frequency band and further configured to apply the second gain to at least the second frequency band; and
a transmissive display coupled to one or both of the left support structure and the right support structure, the transmissive display configured to rest proximate the eyes of a user of the wearable head device.
