I agree with Bob_R that is a really great feature and the first I have heard of it!
If you are getting highs and mids, try unhooking the upper cable at the speakers and listen. Is there bass? How does it sound? Like its rolled off at the lower octaves or smooth just weak?If there's no bass at all somethings amiss.
Try hooking the upper cable to the lower inputs at the speaker. You know there's a signal for the highs. If still no bass its the speaker or internals. If you get bass with the swap when you didnt before) then its the Amp or maybe the cable itself thats to blame.
Be very careful with the exposed and loose speaker end conections! You surely dont want a short! I usually have a few pieces of masking tap around to stick on them just in case.
