It's a common misunderstanding that in-ceiling and in-wall speakers are a compromise for the sake of appearance and thus provide a compromised performance. This need not be the case and certainly is not for Q Install.
The great benefit for the acoustic designer is knowing precisely where in relation to the nearest boundary (ceiling or wall) that the speaker is going to be installed and also not having to worry about resonances and diffraction effects from panels and edges of a speaker enclosure, as there isn't one.
It is perfectly possible for an in-wall speaker to perform as well or even better than a cabinet equivalent. Having high quality sound throughout the home and even outdoors is a luxury to be appreciated.
