Found 22nd Feb 2018
Active subwoifer. Was looking at Peter Tyson for this but found it cheaper at the distributor. Its graphite only for this price. I have managed to get furniture vibrating in the house now, these really make a huge difference when added to my denon and spektor 2 setup (small cones). I know the cone size on this sub is small but for the price it's really brought me to sub 50Hz response.
