KEY FEATURES:
- 99.5 db 1W / 1m average sensitivity
- 51 mm high temperature aluminium voice coil
- 500 W AES program power
- Powerful, ferrite 156 mm magnet structure
- Epoxy anti-corrosion coating of top and back plates of magnet structure
PART NUMBER: 11108F0208
Application : Midrange speaker
The 8M250 loudspeaker is combining high efficiency and 250W power capacity with use of 51 mm aluminium voice coil. It features aluminium die cast frame, 156 mm magnet structure and curvilinear paper cone. The top and back plates are treated with special high quality epoxy electro-deposition coating, which extremely improves the corrosion resistance of the speaker. 8M250 is intended for use as a direct radiating or horn loaded midrange speaker.

1. AES standard. Power is calculated on rated minimum impedance. Measurement is in 18 L box enclosure tuned 82 Hz using a 60 - 2000 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.
