The MTI BR 252 is a high power, arrayable loudspeaker system designed to perform in a wide range of large scale professional sound reinforcement applications.
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.
Features
Applications
The BR 252 can be combined with sub-bass units available from the MTI audio range.
The BR 252 is designed to be used in conjunction with the MTI MPA 82000 amplifier which maximises bandwidth and protects drivers from damage in all modes of operation.
