SPH-135KEP
The Monacor SPH-135KEP features a woven Kevlar cone and phase correction plug yielding a very wide and smooth usable bandwidth - the output to 7 kHz is remarkably flat. With a maximum linear excursion of 6.5mm this drive unit delivers an open, airy sound and is equally at home as a bass / midrange in small bookshelf designs or as a very fine dedicated midrange unit.
