The design objective for this model was to offer a pre-angled version of The12 PRO ACTIVE EXT that can be installed in multiple locations where angling the speakers is mandatory. Such locations include but are not limited to front wide, Atmos and DTS top front and rear, front or rear high surrounds, side surrounds etc. The driver design is perfect for wide angle axi-symmetric radiation to cover a large listening area, with its 30-degree pre-angle meeting the requirements of most 3D home theater builds according to current CEDIA, Dolby and DTS specs.
