The design objective for this model was to offer a pre-angled version of THE10 PASSIVE ON WALL 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. The very flexible speaker mounting and orientation options ensure best possible localization, immersion, and tonal balance at the main listening position while minimizing localization shifts for side seats. THE10 PASSIVE WEDGE 30 is an enormously dynamic and powerful speaker. Its high efficiency and high-power handling allow it to reach reference volume levels and obtain an impressive cinema sound experience even with low amplifier power.
