This model reaches up almost one metre, houses twin drivers, & handles 150 watts, yet thanks to its curvaceous design, visually melts into the background. Up & running – whether it’s the entry-level bookshelf, the OLi centre ground, or the range topping tower – the OLi range speakers are by no means sonic wallflowers: a combination of super-solid cabinets – including the OLi 3’s DALtech damping – & imperiously designed drivers, plus internal components mean the OLi speakers sound just as good as they look.
