    Questions about sub KEF Q400b

    Hi people. I am deciding for a 2.1 setup in the medium range (probbably the low range for most user here), and considered this subwoofer, for some reasons. One is because I can only think about a second-hand decent subwoofer. Spending more than 200€ in a new one is not an option. 160€ I think...
