A positive voltage applied on the red 

terminal produces forward cone motion.

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.

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 75 liter Bass-Reflex test
enclosure tuned at 45Hz.

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.
