SpeakerCraft likes to think of them as simulated rocks containing speakers, not rock speakers. This is because Rox look more like real rocks. Thanks to a new revolutionary process, the speaker remains completely unseen behind a grille that matches the Rox’s surface and texture so closely, that the speaker is nearly impossible to see. Rox enclosure is so durable that it can withstand rain, snow, and hot sun. The finish resembles a rock’s natural finish so exactly, that no one will know it’s actually a high fidelity speaker. The twoway, coaxial woofers are made from a special weatherproof nylon frame that stops the magnet from rusting. Rubber spiders, in the polypropylene woofer, seal the tweeter posts and keep water and moisture from entering the voice coil. Even the wires inside the speaker are coated with silicone rubber so they won’t corrode. When they say tough, they mean it.
