1) Measured on axis in the far field with 1 watt (2.00 V rms @ 4 ohms) input and referenced to 1 meter distance using the inverse square law. Listed
sound pressure represents an average from 300 Hz to 3 kHz.
2) The specifications provide three power values, which are determined by submitting the speaker to a series of laboratory tests lasting two hours
each. In the test for Applicable Power, pink noise is applied in the operating range of the speaker, and the signal is filtered at the ends of the band
with a 12 dB/octave slope. The applicable power value indicated is an rms value. The signal peaks present in the pink noise, adjusted according
to the type of speaker being tested (e.g., +4.5 dB with respect to the average level), are used for determining the Peak Power value. To identify the
Musical Power, the rms power value obtained in the first test is doubled, applying it with impulses lasting 0.5 seconds (0.5 sec ON), and at an interval
of 0.5 second between one application and the next (0.5 sec OFF). For all the tests, the maximum power that the speaker can withstand without sus-
taining permanent damage is assumed as the power value.
