Audio Frequency range of LoL

Greetings, I ask of anyone of what frequency range of sounds league of Legends sends to the speakers.

Something along the lines of number-number. I ask this since im buying a subwoofer and I am wondering if its more or less capable of what the game sending to it. Its a personal project and im buying it no matter what really.

Subwoofer:Dayton 1200 12" from parts-express.
