Our revamped mid-sized stereo indoor/outdoor model sports a 5.25-inch polypropylene driver, resulting in a smaller overall package. The design is elegant, without being attention grabbing, while the sound quality is truly excellent. The series has been designed to suit both commercial and domestic installations. Its easy to adjust mounting arrangement makes it particularly popular in retail outlets. In households, these are ideal for placement on the patio, in the garden or by the pool. With its paintable cabinet and aluminum grille, the I/O 3S is designed to blend seamlessly into its surroundings-so all you notice is the remarkably detailed, great sound.
