Typical System Performance; S2600 Frequency Response & Impedence; S2600 2Nd & 3Rd Harmonic Distortion - JBL S3100 Owner's Manual

TYPICAL SYSTEM
PERFORMANCE:
Figure 5 shows the on-axis sine
wave response of the S2600 sys-
tem taken in a 2π environment
(adjacent to one wall), with contri-
butions from low and high frequen-
cy elements indicated separately.
The dashed line represents the
effect of 4π (free space) loading.
The overall response does not vary
by more than ±2.5dB from 75Hz to
13kHz. The impedance of the sys-
tem is also shown in this graph.

Figure 6. S2600 2nd & 3rd Harmonic Distortion
Figure 6 shows second and
third harmonic distortion for the
S2600 system at a level of 96dB
SPL measured at a distance of
1 meter. The distortion curves have
been raised 20dB for ease in read-
ing. Under these measurement
considerations the low frequency
distortion remains well under 1%.
High frequency distortion is no
greater than 2% out to 8.5kHz.
