I have a sammy 50L7 set while the sound coming from the speakers is nice and crisp there is a clear lack of bass. I have a sub-out on my DVD panny s97. At the moment connecting via HDMI. Could i simply connect free standing bass unit to it to get better bass when watching films cos i dont want to go for all out sound system.???? Also how to get extra bass when watching normal sky digital?? All i need is some bass the rest is fine??
