12GA50

This full-range transducer offers two main points of interest: an extremely high sensitivity (102dB) and an extended frequency response. Both characteristics make it suitable for high quality systems. Moreover, its versatile design allows it to be used as a full-range transducer in guitar or organ amplification or in sound reinforcement systems. Beyond its frequency response advantages, this loudspeaker offers more: it takes profit of the improvements achieved in our low frequency-high power transducers. Thus, it incorporates a high quality voice coil made of high temperature magnet wire and kapton former. Thanks to this design concept of strengthens, the 12GA50 reaches a great power handling.

Key features:

High Sensitivity (102 dB 2.83v @ 1m @ 2pi) and double cone for an extended bandwidth coverage
Special treated surround to obtain an extremely linear frequency response
Short-circuit copper ring for low harmonic distortion and constant impedance modulus
2 aluminium voice coil with kapton former
Designed for high quality full-range reproduction and music instruments reinforcement
