PHYSICAL CHARACTERISTICS
PHL Audio S.A. provides these specifications as representative of current production after conditioning. Because of our continuous research, they are subject to change without notice.
SPECIFICATION NOTES
Note 1 : Allowing for energy response, excursion
capability, Power spectrum, and -3dB low
freq. roll-off for standard reflex tuning.
Note 2 : Established at 20°C ambient temp, according to
AES2-1984 standard using IEC268-1 simulated
programme signal and a 50 liter Bass-Reflex test
enclosure tuned at 53Hz.
Note 3 : Established at 1m on axis of the loudspeaker mounted
in test enclosure, when driven at full AES Power
Handling Capacity, including 4dB of thermal
compression loss.
Note 4 : Measured at 20 mA in free air.
Note 5 : Measured at 20 mA and 20°C ambient temp.
in free air conditions, after full run and rest.
Note 6 : Measured at 20°C ambient temp.
QC limits are ±10%
Note 7 : Stated in RMS voltage according to IEC 268-5.
Note 8 : Includes shipping conditions. The lower limit prevents
from demagnetization.
Note 9: Our products are classified in three categories :
Indoor, Outdoor, and Outdoor
✚
for permanent
outdoor use or severe conditions.
Note 10 : Calculated for front mounting on to a 18 mm thick
board.
