I had a pair of Definitive Technology Prosub 80's and recently added their big brother, Powerfield PF15TLPLUS subwoofer.
This is 500 watts sub and supposedly goes down to 14hz bass extension but I'd be happy if it goes anywhere close to 20hz.
Can't find a manual online on this.
I'll contact Def Tech about the specs.
Anyone using this or similar model?
On a funny note, these three together look like small 2.1 computer speaker system; Prosub 80 as satellites and the PF15TLPLUS as subwoofer.
