Coil made with fiberglass + Kevlar ultralight former, developed for neodymium magnet subwoofers and SPL competitions (dB Drag categories 1-2-5k and above), where maximum efficiency and light weight is critical. Composite material, lighter than traditional aluminum, eliminates self-induced reverse electromagnetic waves typical of ferrous formers. This ensures higher efficiency and optimal response at both low and high excursions.
Filament height: 74 mm
Former height: 180 mm
Outer diameter: 83.6 mm
Inner diameter: 76.1 mm
Wire material: CCAW (Copper Clad Aluminum Wire)
Forming material: Glass fiber + Kevlar ultralight
Number of layers: 8
Wire section: flat
Resistance: 2x1.5 Ohm
Weight: 158g
Strengths: Reduced weight for higher SPL efficiency, better dissipation and stability at high powers, ultralight fiber reinforced construction for extreme mechanical strength
3900 - 4800 W RMS in continuous music regime
9800 - 12000 W RMS for short SPL peaks at low frequency (30-40 Hz)
15,500 - 19,000 W RMS for short SPL peaks at high frequency (60-70 Hz)
Important note on coil power
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.
