Manufacturer Part Number: ME90 The B&C Speakers ME90 1.4 constant directivity cast aluminum horn is designed to accommodate the latest generation of 1.4 exit high-performance compression drivers. Key Features: 80°H x 60°V nominal dispersion Durable cast aluminum construction Constant directivity coverage pattern B&C ME90 1.4 Constant Directivity Horn 80x60 4-Bolt B&C s ME90 1.4 constant directivity cast aluminum horn features smooth medium-dispersion 80° x 60° coverage and its high reliability is a result of all-metal construction. The ME90 is rotatable when installed (may be turned sideways to suit varying applications) and provides very good driver loading down to 900 Hz. Specifications: Nominal dispersion: 80°H x 60°V Minimum frequency: 900 Hz Throat diameter: 1.4 Dimensions: 10.6 H x 10.6 W x 5.5 D Cutout dimensions: 8.8 H x 8.8 W Mounting type: Standard 4 bolt. B&C Speakers produces a series of horns for compression drivers ranging from constant directivity models known for their great consistency in angular coverage to exponential models which optimize acoustical loading and sound energy transfer. Standardized driver mounting flanges give the designer the freedom to choose the best horn/driver combination for each project. All horns are made of cast aluminum resulting in a robust structure that is free from resonances. The only exception to this method is the ME10; a new design that is made from precision molded plastic and incorporates stiffeners that add to its structural integrity. B&C combines advanced design techniques with critical listening tests to manufacture horns that exhibit precise pattern control excellent driver loading and low distortion and coloration.
