FEATURES
•Dual 18 in subwoofer
•SB1000 performance in an 850 format enclosure
•Stacking enclosure without
•Companion to KF850z
DESCRIPTION
The SB850zR incorporates recently developed advances in loudspeaker technology and performance by EAW Engineers. A deeper enclosure was designed to allow use of the same driver used in the legendary SB1000. This significantly enhances the SB850zR performance, providing the same high impact and low frequency response of the SB1000 but in an enclosure footprint matched to the KF850z. The "z" enclosures incorporate a stacking pad on top that mates with a recess in the bottoms. This facilitates stacking the SB850zR with the KF850z.
SB850zR DSP processor settings are available online for EAW's MX8750 as well a select group of other popular touring processors. DSP settings have been engineered to acoustically integrate the SB850zR with the KF850z.
SB850 applications continue to include: concert tours, corporate events, large theaters, stadiums, cathedrals, large live music clubs. Six year warranty.
