I ended up pairing mine with the Klipsch 10" subwoofer. The 12" was actually a bit overwhelming in my office and the speakers don't extend much past the 125Hz range, so I felt most rock and jazz was missing the clean bass hits that you get with the 10". If you mostly listen to rap or EDM you'll be fine with the 12", or if you have a very large room. Otherwise, I'd recommend the 10".
