The MTI BR 252 is a high power, arrayable
loudspeaker system designed to perform in a
wide range of large scale professional sound
The BR 252 is a two-way bi-amplified system consisting of two 15" low frequency drivers in a heavily braced, trapezoid, vented enclosure and a single 2" exit compression driver mounted on a 90 x40 horn.
The system can be used with or without the optional subbass, and has full flying facilities as standard. The extremely high output coupled with low distortion and extended frequency response makes the system ideal for use in high power sound reinforcement situations.
- One box tour sound and installation system.
- Proprietary 2 x 15" low frequency drivers permitting high sound pressure levels with extremely low distortion.
- Proprietary 2" compression driver with extremely low distortion.
- 90° x 40° dispersion for smooth coverage in array situations.
