+2 for all the advice already!

Mine are on a desk, and I hear the midbass 'thud' when I sit too far back. When I actually sit at said desk, everything sounds great, and I have the axis pointing slightly in front of me also. They are probably about 4-5ft apart right now. I am positive the 'thud' is something to do with how the bass fires off solid surfaces either side of the desk. So definitely fiddle with the placement...
As for EQ, I don't apply anything, using the output of an STX. However, I've got an iPod dock hooked up to the 3.5mm input and I were to use that long term I would want to change the EQ on the iPhone- the muddy 'thud' is much more prominent. Might be something to do with your source? Overall I think these are great, perfect volume levels, and they are just so small! Hope you find something that works for you.
