SEAS Orbit OR003-04 FL4RCN/F Aluminum Cone Full Range 40mm/4Ohm
Overview:
The FL4RCN/F is a full range driver offering an extraordinary performance and sound clarity. An aluminum cone with excellent internal damping together with a perfectly matching surround gives a smooth and extended frequency response. The rubber surround offers an outstanding stiffness linearity while keeping the coil well aligned in the magnetic gap even at maximum displacements. A low viscosity magnetic fluid gives extra-stability to the coil increasing the speaker’s power handling. The stiff and stable plastic chassis keeps the critical components in perfect alignment. Featuring a powerful and compact neodymium magnet, the FEA optimised magnet system delivers an exceptional linearity and low distortion. Small size combined with an excellent performance makes this driver the perfect choice for any application where limited space is a critical parameter.
Highlights:
- Stiff and stable plastic chassis keeps the critical components in perfect alignment
- copper cap to ensure exceptional linearity in the force factor and coil inductance
- for any application where limited space
