Installations can be complicated enough, so we have made SIGMA-X series as easy as possible.
From December 2023 shipments, the full range models of SIGMA-X series benefit from additional rear mounting points for use with Powerdrive loudspeaker plates. Four additional sturdy bolt holes have been added to the rear of the SIGMA-X cabinets.
SIGMA-X8 / X10 : Compatible with Powerdrive type 80 plate and WPB-7
SIGMA-X12 / X15 : Compatible with Powerdrive type 90 plate and WPB-7
