Monacor SPH-135KEP Bass / Midrange

SPH-135KEP

£53.73

135mm Kevlar Cone Midwoofer.

Popular 5¼ inch upgrade replacement for Linn Isobarik midrange units - the highly musical performance of the SPH-135KEP surpasses the original KEF B110 and gives new levels of insight and detail.

The woven Kevlar cone and phase correction plug yield a very wide and smooth usable bandwidth - the output to 7 kHz is remarkably flat. With a maximum linear excursion of 6.5mm, this versatile 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.
