Abstract
A canalphone system may include a high audio driver, and a low audio driver adjacent to the high audio driver. The system may also include an amplifier that amplifies an audio signal and delivers that amplified audio signal to the high audio driver and/or the low audio driver. The system may further include a passive audio crossover, the passive audio crossover receives the amplified audio signal from the amplifier and then delivers the amplified audio signal in a suitable frequency range to the high audio driver and/or the low audio driver. The system may additionally include a second amplifier, and a high portion of the passive audio crossover, the high portion of the passive audio crossover to receive the audio signal from the second amplifier and to limit the audio signal delivered to the high audio driver to a high frequency portion of the amplified audio signal.
