ESI Unik 05+ – Active Monitors
Sound On Sound Magazine
by Paul White
ESI’s Unik-series monitors have been extensively upgraded, and now offer even better value for money than before.
I’ve been pretty impressed with the smaller ESI monitors I’ve reviewed over the years, as they invariably offer a good balance of performance and cost. The two-way active Unik 05+, which replaces the earlier Unik 05 we reviewed back in 2012, was developed in Germany and is manufactured in China. The folded ‘air motion transformer’ transducer used to handle the high end is rather different from that used in the earlier model.
Sometimes referred to as a folded ribbon, this tweeter follows a magnetostatic, low-mass design to improve transient performance and to extend the HF range, which now has a 25kHz upper limit in contrast to the 22kHz of the earlier model. The lows are handled by a five-inch Kevlar-composite-coned driver with a distinctive copper-coloured cone that combines light weight with stiffness. This driver includes magnetic shielding.
