This low profile 2" extended range speaker is designed for use in telecom/VOIP devices, where voice capture and playback is the primary design focus. A 25 ohm voice coil is used to allow this driver to be used in many different intercom applications, while providing a very easy load to drive for just about any amplifier.
Additionally, this speaker can be driven to a moderate level using a smartphone or portable music player, making it a great choice for building your own headphones. A headphone amplifier is recommended for louder than moderate volume requirements.
The press-fit faceplate design minimizes center-to-center mounting distance to 2". This allows for line array use up to around 6,500 Hz without comb filtering issues, while 500 to 3,000 Hz frequency response allows it to be used as an upper midrange in multi-way loudspeakers. A weather-resistant design allows this driver to be used in high humidity outdoor applications. Two 2-3/8" long, 24 AWG leads are pre-soldered onto the driver for simple connection.

Note: For higher power handling and sensitivity, it is recommended that this driver be used wired together in groups. Four of these wired in parallel will increase full range power handling to 2 watts RMS, 4 watts max and yield a 6 ohm impedance. Using a high pass filter will also increase power handling.
