Another thing that you should keep in mind is to avoid placing the speakers too close to the wall. Otherwise, they may end up sounding too boomy. Hence, the Q350 requires some space to do its magic.

One of the biggest cons about these magnificent speakers is that they require quite some time to break in. You might have to wait around 80-100 hours!
