V20 Product Description

The Inspired Audio Vector Series is a next generation vertically arraying loudspeaker system, with fixed angle options. Vector 20 features nominal coverage angles of 110° horizontal and 20° vertical. The compact and lightweight enclosure houses a slot loaded 10” cone driver with neodymium magnet structure to cover the 55 – 200 Hz pass band, and two 5” cone drivers vertically aligned to cover the 200 – 2 KHz pass band. The high frequency range is covered by two 1” exit compression drivers mounted on a custom radial vein waveguide, which is centrally mounted in the enclosure. 


The enclosure is manufactured from 15 mm birch plywood and coated in a heavy duty polyurea finish. The cabinet front has a protective steel grill coated in a water resistant powder coat finish which has an acoustically transparent filter medium bonded to its back surface. The cabinet end cheeks have three Kwik Lok pin housings which allow for the attachment of a yoke, or facilitate box to box connection. The rear of the cabinet end cheek has a slot handle to assist handling of the enclosure.

Electrical connection to the cabinet is via two parallel linked Neutrik NL4 MP connectors. Inspired Audio products are designed as an integrated solution complete with system amplifier options from the eFlex range. The eFlex units provide DSP preset functions, networked software control of operating parameters and output drive power. A single output channels from an eFlex Q5/Q6 will drive three Vector 20 enclosures with an eFlex Q20 driving four. 


The Vector V20 can be used full-range for audio visual applications or combined with the reFlex B118 for applications requiring an extended low frequency response.
