Hello to everyone, I am new here. I just bought a Denon AVR-X1400H. This will replace my old all-in-one JVC home theater system. I will keep for a few months my old satellite speakers, but I need to buy an active subwoofer (the old one is passive). One to mach my next loudspeakers. I plan to buy 5 speakers from Indiana Line Nota series. Or something similar. But first, I need a subwoofer. I intend to spend no more than 350 Euros for the sub. What do you say? Please share your experience.
