You should see what I’m talking about there ;-)
I once had the smaller stand-mounted version of the Talon speaker, their sort of "mini-Khorus," to evaluate. Those speakers were so bad, sounded so odd, muffled and colored I literally thought they must be broken. (Turns out they weren't broken...that was just their sound).
