The problem with the top-mounted speaker is that the highs are directed 
away from the operator.  The result, for CW, is a mushy, thumpy sounding 
signal which is hard to copy at high speed.  I've found that holding a 
flat plate at a 45 degree angle to the top of the rig helps, as does 
putting a large PVC pipe elbow over the speaker, but these aren't 
elegant solutions.

However...what about an EC2 with a small 'tweeter' in the front panel 
and a larger 'woofer' on top?  I bet there would still be room for an 
optional switching PS in there.
