The NX series utilizes high-density medium-density fiberboard coated with black textured epoxy resin. A robust black metal grille protects the front, while the inner side features an acoustically transparent sound foam backing that ensures dust and moisture resistance. Each speaker's base includes a sturdy steel pole socket for mounting on stands or subwoofers. Mounting points are provided for suspending speakers, offering maximum architectural freedom during installation anywhere. Threaded inserts accommodate optional mounting hardware for fixed installation applications.
