Designed to meet exacting standards, the Loewe Klang 5 Subwoofer in Graphite Grey KLG5SUB features an acoustic concept that uses one active speaker with two passive membranes to generate warm and authentic low frequencies. A high 600-watts of music power ensure a strong, concentrated bass from this elegant home theatre speaker system. This Loewe Klang5 will seamlessly integrate with the Loewe Bild 5, Bild 7 and Bild 9 TVs(sold separately). An integrated 5.1 audio decoder with Dolby Digital, DTS system and the DAL wireless sound system can be used in conjunction with the Bild 5, 7 and 9's integrated soundbar to create a surround sound experience.
