There is always hope when a speaker sounds better after the first impression.
They do seem to have a different sonic signature, compared to many speakers that I have owned.
However, they sound right, focused and balanced to me. I believe they were engineered for best
performance with them grills off, you can even put the grills over the back plate, when doing some
serious listening. While I am not much for speaker break-in, the bass did sound better to me as the
playing time increased. The bass is there - however, it really depends on the recording. They can and
will go low.
A lot of speaker companies tend to have a so-called sonic signature (sound). However, these seem to
be less colored than anything that I have heard.
Just give it some more time - so, the speakers can become more use to you.
