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