Christie subwoofers employ high-performance driver components and feature an advanced cabinet design which is heavily cross-braced and tuned with EBS (Extended Bass Shelf). This allows Christie subwoofers to deliver powerful, deep bass with minimal distortion and power compression for extremely high output levels and extended low frequency response. Matching the high-performance capabities of the rest of the Christie Vive Audio solution, these cinema subwoofers produce the deep and impactful bass throughout the entire auditorium.
Features:
- High cubic displacement cabinet, heavily cross-braced, vented and tuned
- Each driver has a discrete, vented internal enclosure, for optimal performance
- Extra large vent area with rounded edges for minimal air turbulence noise
