1. AES standard. Power is calculated on rated minimum impedance.
2. Measurement is in 125 L box enclosure tuned 56 Hz using a 40-400 Hz band limited pink noise test signal applied continuously for 2 hours.
3. Program power is defined as 3db greater than AES Power Capacity.

15B500 loudspeaker combining good linearity and efficiency with high power handling capabilities, with use of 77 mm voice coil. It features aluminium die cast frame, water protected cone, 180 mm vented magnet structure and 20 mm high voice coil. It has aluminum demodulating ring that reduces distortions and improves cooling of voice coil. 15B500 is suitable for application in a wide variety of enclosure types and particularly as LF driver in 2- or 3- way systems.
