In sum the Lg PK7 is a good portable speaker with rich sound, substantial bass and reasonably good reproduction.

Awesome bass and clear quality sound

The bass, for what it is, is good

It is somewhat less good at the high end, which is true of most boosted bass speakers in my experience

It is a boosted bass speaker,, and those who love bass will love it.

It has very rich bass and also can be played surprisingly loud.

If the option were available I would rate it 4.5 because the high end is clipped and not as rich as the bass.
