Our Dynasty Spas Poseidon replacement cover is designed to fit over the raised speakers with the main cover being built with cut outs for these stereo speakers allowing it to lay flat and creating a seal against the lip of your spa. The speakers are then covered with our special designed velcro detachable speaker flaps. The speaker flaps are insulated and have a soft foam core that are designed to eliminate the steam from escaping around the speakers and creating the perfect hot tub cover.
