Guys, I'm planning to use both Edifier R1280T Bookshelf speakers and Logitech Z623 (for subwoofer) in my PC. Dili ba kani maka reduce sa sound quality ang 3.5 mm splitter? Found this one in Lazada, dual audio-out only. Secondly, sa mga naka gamit na, what do you think about this combination? R1280T + Z623?
