This is a set of 2 rectangular enclosed 2 Watt 8 Ohm speakers used on many audio/visual projects.
It is easy to mount since it is enclosed and has 2 mounting tabs, and the volume / audio quality is quite decent for a speaker of this size and power.
Dimensions: 53 x 18 x 14mm
Comes with 2 sets of 37mm (14.6 inch) wires incorporated into the units and terminated by a JST-PH 4 position header (2.00 mm pitch).
