Explanatory Note on Specifications (at the back of the manual)

On the back of this manual you will find the specifications of your loudspeaker

The Dimensions refer to the outer dimensions of the loudspeakers. Likewise the Gross Volume includes the entire
speaker.
Drive Units describes how many drivers and which types are contained in the loudspeakers.
The Nominal Power of a loudspeaker describes how much electric power may be supplied to the loudspeaker over
a long period of time without damaging the loudspeaker through overheating of the drivers. To determine the
nominal power, a statistical mixture of different frequencies with different volumes is used as electric signal. This
"composite signal" is selected so as to correspond on average to the spectral distribution of different kinds of music
(s. DIN 45753). Thus the total power supplied to the speaker in the determination of the nominal power is distributed
to all the drive units at a particular ratio. If the electric power corresponding to the nominal power were delivered to
a single driver, it would normally be destroyed.
The Peak Power defines the short-time power handling of a loudspeaker e.g. with respect to music pulses. The
destruction of a loudspeaker by exceeding the peak power is mostly caused by mechanical damages in the
drivers, e.g. by being displaced too far.
The Frequency Range of a loudspeaker is defined by the upper and lower cut-off frequencies of the SPL frequency
response. At the cut-off frequencies the sound pressure level decreases by 8dB (factor 2.5) as compared to the
midrange. Given a standard domestic room, the effective lower cut-off frequency may deviate from standard values
due to room resonances.
The Sensitivity of a loudspeaker specifies the sound pressure produced in a dead room at a distance of 1 meter
from the loudspeaker if 1 Watt electric power is 'transformed' in the speaker.
Additionally, a further sensitivity value is given referring to an input signal of 2.83 volts.
The Nominal Impedance of your loudspeaker normally is 6 or 8 ohms.
Minimal impedances in ohms are given together with the corresponding frequency
The Recommended Amplifier Power is given as a range. The lower limit can be recommended only if it does
not exceed a moderate volume too distinctly
