SEAS Prestige H1602-04/06 L12RE/XFC Coaxial Drivers
Overview:
The L12RE/XFC is a coaxial loudspeaker providing high quality sound in a very compact format. The coaxially arranged precoated fabric dome high frequency unit has a low resonance frequency, and integrates with the cone driver to a point source. Voice coil windings immersed in magnetic fluid increase short term power handling capacity and reduce the compression at high power levels. The cone of the woofer acts as a moderate horn loading for the tweeter, and the chassis of the dome unit represents the throat of this horn. The stiff, yet light aluminium cone acts as a piston throughout the recommended frequency range.
Highlights:
- Long term power handling (RMS) is 80 Watts (Woofer) and 90 Watts (Tweeter)
- Coaxial loudspeaker providing high quality sound in a very compact format
- The cone of the woofer acts as a moderate horn loading for the tweeter, and the chassis of the dome unit represents the throat of this horn
