Ease of installation, great sound.

None that I have found.

I purchased these speakers, without the benefit of
hearing them beforehand. My wife did not like
the ideal of having two more speakers in our
living room…so a compromise was made.

First – The Install: Almost everything I have
done recently to setup my home theater has
turned into a nightmare, so I was expecting
the installation of these speakers to take, at
least, 4-5 hours…. Nothing could have been
further from the truth! I mounted one speaker
in the ceiling on each side of my center couch.
It took maybe an hour…including cleanup.

Next – The Sound: In a word – amazing!
These are great sounding speakers with a
flat frequency response, clean and accurate
timbre, and great bass. They are capable of
playing loud without strain, and can shake
the room if you are in to that kind of thing.

The only change I may make is to put a box
Around them in the attic, since I really don’t
want dust getting in them, and since the
nighbors can probably hear them because
the speakers are not enclosed.

I am a very satisfied customer. Way to go
Paradigm!
