Coil made with 100% copper filament and anodized Aluminum backing, developed for subwoofers with ferrite and/or neodymium magnet, for Demo (music media) and SPL competitions (dB Drag categories 1-2-5k and above), where maximum resistance and heat dissipation is essential. Aluminum, which is lighter than traditional copper, provides greater performance and optimal response at both low and high excursions.
Filament height: 40 mm
Shaper height: 90 mm
Outer diameter: 63.8 mm
Inner diameter: 60.5 mm
Filament material: Copper
Former material: Anodized aluminum
Number of layers: 4 Bifilar
Wire Section: Round
Resistance: 2+2 Ohm
Weight: 76 g
Strengths: Reduced weight for higher SPL efficiency, better dissipation and stability at high powers, kapton reinforced construction for extreme mechanical strength.
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
Frequency spectrum used and type of musical signal
Number and stiffness of spiders and the relative mechanical compliance
Magnet and coilventilation system
Total moving mass that the speaker must 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 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.
