Hello everyone I am on a budget of $220 and I am having some difficulty deciding on which subwoofer to buy. My room is about 18Lx12Wx9H. I have narrowed it down to three choices, valodyne vx 10, polk audio psw303 and jbl sub 10 venue series. The sub will be used mostly for music 60/40 which of the three will deliver the cleanest bass and deliver an overall better bang for the buck.
