Best Fine Wire Voice Coil

JBL Professional JRX212 Portable 2-way Sound Reinforcement Loudspeaker System, 12-Inch

JBL 12-Inch low frequency driver with a 2.5-Inch diameter edgewound ribbon voice coil which provides more cross-sectional wire area in the voice coil gap than round wire designs, for greater efficiency and power handling..
JBL 2414H-C 1-Inch polymer diaphragm compression driver improves high frequency performance as well as system reliability..
The advanced network topology crossover design shapes frequency response and delivers "coherent summation" in the crossover region..
High-voltage capacitors and inductors with massive cores and heavy gauge wire enable the crossover network to handle high power without saturating..
Non-resonant, all-steel handles are used..
Attractive 18-gauge hexagon perforated, steel grille protects components from damage.
Dual-angle pole-mount socket allows the speaker to tilt 10°for more uniform audience coverage..

2 PACK OF POWERFUL SUBWOOFERS: 2 pack of 12-inch, 3500-watt subwoofer with an overcompensating motor structure for increased magnetic strength.
IMPRESSIVE PERFORMANCE: 12-millimeter T-yoke and top plate improve low-frequency dynamics.
3-inch, 4-layer voice coil with direct connect wire increases power handling.
PROTECTION FEATURES: Vented T-yoke and frame reduces voice coil heat build-up.
High-temperature tolerance adhesives resist thermal failure.
Stitched voice coil leads prevent potential damage.
Non-transfer Spruce pulp cone with UV and chemical protection.
DURABLE DESIGN: Non-magnetic, non-resonate die-cast aluminum frame is lightweight yet durable.
Stitched and glued surround and cone joints for strongest bonding.
INCLUDES: 2 1-piece gasket/trim Ring with concealed mounting holes included.

Most car audio system designs call for 2- or 4-ohm impedance. Kappa Series subwoofers put the choice in your hands..
The Kappa Series voice coil employs a two-sided, ducted airflow design that cools the voice coil, increases power handling and improves reliability..
Kappa subwoofer cones incorporate glass-fibers for exceptional accuracy and detail. Inherently non-resonant, the glass-fiber cones eliminate distortion so your music—and nothing but your music—comes through loud and clear..
The terminals on the Kappa subwoofers accommodate up to 8-guage wire (8.37mm 2 cross section), which transfers low-resistance, low-loss power to the woofer, even over long wire runs..
