The range of elegant wall-mounted speakers is rounded off by the Ambient 88F active subwoofer, which boasts a high-performance power amplifier with Class D technology and delivers rich sounds down to a cut-off frequency of 24 Hz. Nevertheless, the woofer, which utilizes a 200 mm chassis, is still ultra-compact and measures just 16 cm deep. This means it can fit almost anywhere next to, or under, a piece of furniture or even behind your curtains. The volume and crossover frequency can be infinitely adjusted via the controls on the underside. The 88F is also available in a silk-matt black or white finish, so you don?t necessarily have to hide it away. The woofer itself radiates downwards, with the bass reflex openings located at the front or side depending on the setup.
