L12-854K

MID-BASS

L12-854K

High efficiency mid-bass.

Very high sensitivity, excellent linearity and very low distortion.

Applications
  • • A very light moving mass, a curve response linear above 3 kHz makes the L12-854K a very good solution for high quality two or three way system.
  • • Very easy to crossover and ideal in conjunction to small size 1 inch compression drivers.
