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 150 liter Bass-Reflex test enclosure tuned at 40Hz.
- 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
