Enjoy deep, rich bass from this powerful active subwoofer. The 250mm cone diaphragm can move a larger volume of air, producing powerful low-end resonance that makes bass sound rich and authentic. The subwoofer reinforces low frequency sounds in movies and music for a great multi-channel home theatre experience. The perfect partner for today’s bass-driven music. Many speakers use paper cones that flex and deteriorate over time, leading to a more distorted sound. Mica Reinforced Cellular (MRC) fibre woofers are rigid, holding their shape even when moving at high pressure and speed, so you can drive the bass harder without compromising your audio quality.
