Mr. Steam MSSPEAKERSSQ-WH are wall or ceiling mountable square speakers designed for use in steam rooms. They have a 60-watt peak power handling capacity and a 30-watt RMS power output, with an 8-ohm impedance. The speakers are designed to be watertight and can be installed in either walls or ceilings. They come with mounting brackets that rotate out and tighten when the 4 large screws are turned clockwise. The speakers also have a removable front grill that can be popped off by gently rotating out any two opposite brackets and pressing them down.
