OFFLINE Eminence Delta Pro 12A 400W 12'' Speaker, 8 Ohm

Full Description

Precise, Optimised Design

Eminence professional range speakers are constructed with aluminium baskets, which are lightweight and do not conduct magnetic fields - this reduces interference to the moving components, and optimises motor strength for a powerful and efficient speaker design. Every aspect of each speaker is precisely assembled, down to the epoxy-acrylic finish which is applied with an accuracy within 0.001’’, meaning you can trust every Eminence professional speaker to perform when you need it.
