Yes. An amplifier. Powered subs generally have a power amp only for themselves and you need to add a power amp for the bookshelf speakers.
Connecting Bookshelve Speakers to PC
I want to connect a pair of Linn 5110 speakers to my PC. I think I need to get a sub and power the speakers off of the internal amp and run a mini DB cable for the line out of the PC to the sub. Is this correct? Can anyone recommend a sub to do this with? All of the subs I am finding have RCA out for H.T. Am I missing something?
TIA
