by better bass in what way? Polk is known for publishing low freq responces, but you should listen and judge for yourself. I love my B&Ws, but some dont. In the same price range id take bw over polk. Jamo has been up and down but have a history of good speakers, especially in europe. I believe they are a part of klipsch now. If your looking for bass from a bookshelf, i found getting below 40hz accurately isnt widley avialable. speakers tend to sound muddy. Is this for 2ch music?
