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.
