The Q Acoustics Professional in-ceiling stereo speaker features the latest styling and stereo speaker technology that is designed to meet the most demanding of your requirements. They give you the ability to listen to music throughout your home, even in bathrooms as they are moisture proof. Whereas before you were not able to listen to the same music in many rooms due to the impractical nature of having the speakers dotted around in each room, the Professional in-ceiling stereo speaker now lets you do that.
