125.5 - 131 H78 - D 1 ohm 4-layer aluminum flat wire - GS Audio Coil
Coil made with 100% aluminum filament and anodized Aluminum backing developed for subwoofers with ferrite and/or neodymium magnet, for Demo (music media) competitions and SPL (dB Drag categories 1-2-5k and above), where maximum efficiency and lightness is essential. Aluminum, which is lighter than conventional copper, provides greater efficiency and optimal response at both low and high excursions.
Filament height: 78 mm
Shaper height: 195 mm
Outer diameter: 131 mm
Inner diameter: 126 mm
Filament material: 100% Aluminum
Former material: Anodized aluminum
Number of layers: 4
Wire section: flat
Resistance: 2x1 Ohm
Weight: 286 g
Strengths: Reduced weight for higher SPL efficiency, better dissipation and stability at high powers, ultralight fiber reinforced construction for extreme mechanical strength
4900 - 6100 W RMS in continuous music regime
12200 - 15200 W RMS for short SPL peaks at low frequency (30-40 Hz)
19500 - 24500 W RMS for short SPL peaks at high frequency (60-70 Hz)
Important note on the power of the coils
The power ratings given for loudspeaker coils are for technical and comparative purposes only. The actual power handling of a loudspeaker depends on multiple factors, including:
impedance and how it is connected to the amplifier
spectrum of frequencies used and type of musical signal
number and stiffness of spiders and relative mechanical compliance
se ventilation system of the magnet and coil
moverall moving axle that the speaker has to move
and many others...
For this reason, it is not possible to define a single, universal value of manageable power: actual performance can vary considerably depending on the design and conditions of use.The user is therefore urged to consider the data as indicative and to pay attention to the correct match between amplifier, loudspeaker and installation.
