LaVoce's compact DF10.142LK 1" exit compression driver delivers smooth high frequency response with excellent detail and accuracy. The lightweight 1.4" polyimide diaphragm produces response all the way up to 20,000 Hz with minimal resonances to minimize unwanted peaks and dips. At only 3-1/2" diameter this driver is perfect for designs where space is at a minimum, such as stackable line arrays and mobile audio systems.
