AM4215/64 is a medium power 2-way full-range loudspeaker system comprised of one 380 mm (15 in) low frequency driver and one 38 mm (1.5 in) exit/38 mm (1.5 in) voice-coil compression driver. The large PT Progressive Transition waveguide provides well-controlled 60° by 40° coverage and is rotatable for cabinet positioning in either horizontal or vertical orientation. High-slope crossovers minimize band overlap and well-controlled off-axis response enhances arrayability.
1 Bi-amp mode, with recommended active tuning.
2 Resultant engineered acoustical response of crossover network and components.
3 AES standard, one decade pink noise with 6 dB crest factor within device's operational band, free air. Standard AES 2 hr rating
plus long-term 100 hr rating are specified for low-frequency transducers.
4 IEC standard, full bandwidth pink noise with 6 dB crest factor, 100 hours.
5 Calculated based on power rating and sensitivity, exclusive of power compression.
6 Anechoic sensitivity in free field, no additional sensitivity gain from boundary loading.
JBL continually engages in research related to product improvement. Changes introduced into existing products without notice
are an expression of that philosophy.
