Like its gemstone namesake, Eton’s ONYX series should catch the eye – or ear – of in-car enthusiasts. It’s comprised of three separate high-end speaker drivers, all engineered for a premium performance. Both the 80mm ONYX 80 midrange and 165mm ONYX 16 bass/mid driver use ribbed paper cones, neodymium magnets and ultra-stiff aluminium die-cast baskets, while the ONYX 28 hand-coated fabric dome tweeter is housed in a flush-mountable enclosure with vented rear chamber. Each is designed for the highest musical performance, but are meant, of course, to be used together. Combine them in three-way active speaker system to get the ultimate high-end sound experience.
