The I/O 3S, Jamo’s revamped stereo mid-sized 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 stereo 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.
