The 53Qw is a specialized boundary application speaker system for integration into a 90 degree corner, such as at 2 walls or a wall and ceiling. This model is ideally suited for immersive 3D audio systems, such as Atmos, Auro3D, DTS:X, or for traditional music and home theater application when the speakers need to be mounted up high. This would include outdoor trellises, pergolas, under eave etc. This versatile speaker works well in residential and commercial installations where it can be located at ceiling and wall junctures to provide excellent sound performance yet minimal visible intrusion into the space, and with its compact design, this series easily integrates into any environment, both indoor and outdoor. With (2) James proprietary 5.25" high excursion woofers, and the signature James aluminum dome quad-array tweeter, this compact speaker offers silky smooth response across a broad range of frequencies. All James transducers feature aluminum cones and Santoprene™ surrounds for outdoor and marine rated use.
