The drivers that are used for in-ear monitors, are also known as balanced armatures. These very small speakers can build a relatively large sound pressure.

Different models of speakers are used, depending on the type of in-ear monitor. Often Dual-drivers are used to achieve more efficiency. These are two similar tandem switched drivers. With a multi-way system that uses multiple drivers, each speaker has its own frequency range.

Also electrical components are added to the cross filter, which ensures that each driver is assigned to its own frequency. Acoustic filters are applied to linear balance the frequency characteristics.


A one-way monitor uses one driver. This driver is able to provide both high and low frequencies. It also uses an acoustic filter to better balance the characteristics of the driver.


A two-way system is determined by a unique in-ear monitor cross filter that, through a crossover frequency, ensures that only the bass and the higher frequencies are passed to the relevant drivers. The low and midrange driver is only responsible for frequencies below 3 KHz and the high driver with 3 KHz and higher.


A three-way system has a cross filter for three different frequency ranges for three different drivers.
• A bass tone driver can uninterrupted handle bass without the highs interfering.
• A midrange driver that is devoted solely to, and naturally represents the vocals.
• A high tone driver for the highest frequencies of instruments that will make them sound sparkling clear
