The AES 2 - 1984 Standard specification by Audio Engineering
Society, is representative and commonly used for the measure
in Professional Sound Reinforcement.

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.

In this way, the declared power of ALTO passive speaker cabinet,
is comparable to the RMS voltage value, measured on the equiva-
lent power amplifier for the same value of impedance.

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.

The PS 2TW/2TWA speaker cabinet also provides the
suspension points for fixed installation. How to use them?
