The Q Acoustics M4 features advanced ‘BMR’ (Balanced Mode Radiator) speaker drive units, which produce extraordinarily wide sound dispersion. This not only creates clear room filling sound, but also means every listener will enjoy the same outstanding sound quality wherever they sit in the listening room. The M4’s real bass is created by its acoustically matched, built-in, high performance subwoofer. You will enjoy a genuine ‘cinema’ audio experience with the Q M4, compared with using your TV speakers alone. Naturally, because the Q M4 is a ‘hi fi’ soundbar, it is designed to play music and movies with equal accomplishment. With both analogue and optical inputs, the unit is in reality a complete one-box, standalone hi fi system in it’s own right. It can also be used with a variety of other entertainment sources such as streaming services like Spotify, CD players, portable music players, computers and internet radio.
