I have used the Nano 300 for several months now, although the last couple I haven't gotten out there much.  I am quite pleased with it.  Yes, the bass is more pronounced.  The Compacts are a little easier and quicker to set up, but the Nano is quick enough.
I use two of them.  That's redundant for a lot of jobs, but I enjoy the extra  power when needed and I always have a backup in place should one fail.
The Compact has a bit larger coverage area before the sound drops off, maybe, but not as much as I expected.  Hasn't been a problem.
Frankieve sells them for about half the price of a Compact.
