Mid-range and (Sub)Woofers
Mid-range and (Sub)Woofers
Multi-driver IEM’s require specialized drivers for low, mid and high frequencies. All of our balanced armature drivers are able to deliver mid-range frequencies, but some do it better than others. Here you’ll find our selection, together with a variety of single and dual armature woofers.
