It seems like you’re describing a bullhorn with two tenons and a square base that can rotate 180 degrees. A bullhorn is a type of loudspeaker or horn loudspeaker commonly used for public address systems, outdoor events, and other applications where sound needs to be projected over long distances.
The term “two tenons” likely refers to the mounting points or brackets that allow the bullhorn to be attached to a pole, wall, or another support structure.
The “180D SQ BASE” likely indicates that the base of the bullhorn is square and can rotate 180 degrees, meaning it can be adjusted or pivoted to direct sound in different directions as needed.
This type of bullhorn design allows for flexibility in directing sound and mounting options, making it suitable for various outdoor and public address applications.
