This could be a break in issue, but there may be other things involved;
First, these are bookshelf speakers so they will be limited in bass response.
Their web-site rates these speakers' response as 50Hz to 20Khz, but they
don't give any information beyond that, so there's no way to know how linear
is the response bewteen those frequencies. This leads me to suspect some
roll-off at the extremes, especially in the bass, which is already limited.
You could also be accurately sensing something in the room. Most rooms roll
off the highs and have big peaks and/or valleys between 35Hz and 120Hz.
You can go to several sites on the web, load in your room dimensions and get
some idea about the problems in your room. It also has something to do
with speaker placement, room treatment, drapes, carpet, hardwood floors,
etc. An absorbant room can roll of your highs and certain room dimensions
make it hard for bass to resolve itself. If your previous system bumped up
the highs and lows it may have covered this problem. This would also
account for the new system sounding mid-range heavy.
These speakers have limited bass response, may have a roll off in the high
end, and/or your room may be rolling off the high end and/or your room may
have significant suck outs between 50hz and 120 hz, which would rob your
speakers of their already limited low end.
First things first -- give your new speakers a chance to break in.
