Abstract
A multi-driver, in-ear monitor is provided that is coupleable to an external audio source, for example via a source input cable or a wireless receiver. A circuit, for example comprising a passive or active crossover circuit, receives the electrical signal from the external audio source and provides separate input signals to the drivers contained within the in-ear monitor. A plurality of sound delivery tubes acoustically couple the audio output from each of the drivers to the acoustic output surface of the in-ear monitor. The in-ear monitor may be configured as a custom fit IEM or configured to accept a removable eartip. The plurality of sound delivery tubes may be comprised of a pair of concentric tubes; a pair of concentric tubes and a discrete tube; or three concentric tubes.
