The ELAC SUB 101 Active Subwoofer known for high-quality audio components for creating a cinematic sound experience at home. The Elac Sub 101 ESP subwoofer delivers powerful and precise bass. Enjoy immersive sound quality and bring your movies to life with this premium audio setup from ELAC. This subwoofer powers on and shows both red and green light between being 'off' and 'on'. However I am unable to test with an amplifier so sold as spares/not working.
