The ZERO Series is a first of its kind innovation for Wet Sounds, taking the legendary REV tower speaker performance and reimagining it for optimal use in more confined spaces. The high output in small, sealed enclosures means ZERO Series allows for ZERO compromises. These speakers can also be used with or without a twist-lock grille, making them ideal for both custom and OEM replacement applications. The ZERO Series speakers and subwoofers utilize materials such as Nylas, a composite of nylon and fiberglass, providing improved stability and superior strength versus conventional speaker materials. • Shallow mounting depth • Optimized for small sealed enclosure application • Twist-lock grille hides mounting hardware • Install with or without grille
