i have this sub powered by a rd audio 1000.1d.
its the single spider version so it handles lower power.
this sub is amazing. it has a very warm and deep bass when listening to music like r & b or jazz. on rock music, the bass guitar just comes alive. of course the recordings have to be good.
now on to bass songs. it hits hard boys and girls. lol. i was shocked at the output.
over all i give this sub 10/10.
hear are the subs i have owned to compare.
