The reFlex B215 is a compact high power bass enclosure designed to operate over the 40 – 135 Hz pass band. The reFlex B215 is a variant of the Optima B215 based on a shared enclosure but without the fly track system giving it identical acoustic performance. It has applications within both touring where it might be the bass companion to the Optima 5 array or products from the mFlex and Axis ranges. The reFlex B215 also has applications within fixed installation where it can be combined with products from the Optima, mFlex or Axis ranges.
The cabinet combines two off 15” long excursion cone drivers with neodymium magnet structures loaded into a twin chamber band pass structure. The enclosure is manufactured from 18 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. Each cabinet has four handles and the option of rear panel mounted castors. The cabinet base has polyethylene runners and the cabinet top panel housings to aid stacking cabinets in vertical columns. The top panel contains an M20 plate to allow cabinets to be pole mounted above it. Three cabinets in a vertical stack have the option of being used in a cardioid mode with the bottom cabinet inverted.
Electrical connection to the cabinet is via either two parallel linked Neutrik NL4 connectors on the rear panel allowing a direct connection from an eFlex Q20 system amplifier. Alternatively a third Neutrik NL4 connector allows a bridged input from an eFlex Q5 system amplifier. An additional Neutrik NL4 on the front grill allows connection from an eFlex Q20 when a cabinet is inverted in cardioid mode.
All 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 pair of bridged eFlex Q5 output channels will drive a single B215 enclosure, while an eFlex Q20 will drive two B215 enclosures per output channel.
