The YU2 speakers sound very good but the bass was a bit lacking

Listening to my kids watch some action-type movie the other day, I was struck by the significant bass-boost this little sub was able to put out.

This is the most clean bass you will get out of a sub this size.

It will not shake your windows or win any SPL contests, but it will produce a really nice bass note

We're not looking to blow the roof off, but it's definitely enough to provide the proper bass for our room.

(there's a more "powerful" all-white speaker I also found on Amazon, but it cost $250 more than this one,
