Wonderwall Music Resort is a leisure complex in Gandía (Valencia) dedicated to the musical atmosphere and to the animation. In its facilities are held weekly during the summer months themed parties and sessions of famous DJ's. Also, Wonderwall Music Resort hosts music festivals, such as the SanSan Festival.

The large audio system mounted in this installation has numerous units of two lines of MARK speakers: the MBS series (series 5) and the MP series. Specifically, all the loudspeakers of this series are installed on an aluminum truss structure in the resort area dedicated to the part of the DJs and discomóviles sessions. These speakers are also located at specific points of the installation to act as sound reinforcement.

The MARK MBS series is made of ABS injection plastic and features an elegant design. This series is especially suitable for touring applications, combining a rugged enclosure with great portability, with a rigging rail, stacking possibility and a lower insertion tube.

This wide range offers in its passive configurations acoustic boxes with a permissible power between 200W and 400W depending on the model, which allows to choose the appropriate speaker according to the needs of the installation.
