3. SUSPENSION POINT
The PS 2/2A speaker cabinet also provides the suspension
points for fixed installation. How to use them?
Eyebolt
First, open the dust covers, and the next, mount the flying
rings to the suspension points (M10 1.5PH LENGTH: 30mm).
For further details, please refer to the right illustration.

It is defined as the square of the RMS voltage generated with a
pre-defined and band-passed Pink Noise Signal, applied con-
tinuously for 2 hours, on the assembled speaker cabinet.
