15B450     PART NUMBER: 11115F1108
15B450A   PART NUMBER: 11115F1208
15B450A2 PART NUMBER: 11115F2708

 

Application : High power woofer

15B450 loudspeaker combining good linearity and efficiency with high power handling capabilities, with use of 77 mm voice coil. It features aluminium die cast frame, 180 mm magnet structure and 19 mm high voice coil.The top and back plates are treated with special high quality epoxy electro-deposition coating, which extremely improves the corrosion resistance of the speaker. 15B450 is suitable for application in a wide variety of enclosure types and particularly as LF driver in 2- or 3- way systems.

Version 15B450A has one aluminium demodulating ring.
Version 15B450A2 has two aluminium demodulating rings which reduce modulation of magnetic flux in airgap for lower THD of the speaker.

1. AES standard. Power is calculated on rated minimum impedance. Measurement is in 120 L box enclosure tuned 56 Hz using a 40-400 Hz band limited pink noise test signal applied continuously for 2 hours.

2. Program power is defined as 3db greater than AES Power Capacity.

* Linear Mathematical Xmax is calculated as: (Hvc - Hg)/2 + Hg/4 where Hvc is the voice coil depth and Hg is the gap depth.
