kost - please don't enflame this conversation as you have done with many other conversations. We have already determined and stated that bass is a limitation of the speaker's woofer characteristics and box design. OP is simply asking if there is any way cables can improve things. While I agree that cable has somewhat of a limited effect here, it can make the existing bass signals a bit stronger.
roberjerman - see my statement. Obviously, as stated before, OP speaker is limited on woofer/cabinet design.
