Abstract
A canalphone system may include a high frequency sound bore carried within a canalphone. The system may also include a low frequency sound bore adjacent to the high frequency sound bore to form a single unit, the low frequency sound bore and the high frequency sound bore being sized so that the low frequency sound bore and the high frequency sound bore each deliver sound with similar time and phase. The system may further include a high acoustical driver carried within the canalphone where the high acoustical driver delivers sound through the high frequency sound bore. The system may additionally include a low acoustical driver carried within the canalphone where the low acoustical driver delivers sound through the low frequency sound bore.
