The surface-mounted back box for the 7" Install speakers is used wherever direct installation in a ceiling or wall is not possible. This means that no intrusive work into the fabric of the building is necessary to bring perfect sound to where it is needed.
The sound of the Install 7 speakers is also further optimised by this surface-mounted box, as the bass can be transmitted even more richly thanks to the cabinet design. As less power is therefore required for bass reproduction, the other sounds are reproduced even more clearly, strongly and voluminously.
