One subwoofer can transform your listening enjoyment of music and film by offering a deeper, richer, more tuneful bass response. The subwoofer can deliver more impactful sound to bring your story to life. It’s the “0.1” in the “5.1” channel system, and is most effectively used with 5 other speakers. These can include front and rear speaker pairs, and a centre speaker. Variations may include small satellite speakers, bookshelf speakers or floor standing speakers.
