BT-12 Features

SPL lobe ::: Specifications

Easy, simple and intuitive operation: releasing a knob, moving the tilt lever and retightening the knob.
The BT-12's parts are precision manufactured using state of the art Laser cutting and CNC bending. The result is a precise and accurate device that offers smooth operation as well as a pleasing appearance.
Adjustable to any tilt angle from -12º to +12º.
A scale is available on both sides of the adaptor for convenient and clear reading and setting of tilt angle.
Enables optimal vertical aiming of the loudspeaker by tilting it without sacrificing stability and safety.
Maintains balance of the loudspeaker throughout its tilting range by keeping the cab’s COG (Center Of Gravity) over the stand’s pole.
Eliminates extra and uneven loads and stresses on different parts of the tripod stand.
Fits all standard loudspeaker poles and loudspeaker pole caps (top hats) of 35mm (1-3/8”) diameter.
Suitable for loudspeakers weighing up to 45kg (100lb).
Adds 150mm (6”) to the stand/pole height.
The loudspeaker is prevented from rotating on top of the BT-12 by its weight pressing against a rubber foot.
The rubber foot also takes most of the horizontal loads off the top hat assembly.
The complete adaptor and loudspeaker can be easily rotated about the pole and locked with the knob provided.
The BT-12s are supplied with specially routed foam packing inserts, to be placed in your favorite road case, for handy, efficient and protective storage between uses.
Optional Quick Mount for Laser pen/pointer for easy and quick aiming of the loudspeaker is available.

spl_lobe

This is a general example of an SPL lobe of HF out of an average FR loudspeaker, properly tilted for a low & flat seated audience. Note how by down-tilting the cab (by only 10° in this case), the SPL gradient is brought to closely tangent the listening zone throughout the audience depth, thus greatly improving the level consistency over a wider area of listeners.
