The power handling of its beautiful under-hung radial TCSounds Pro-5100 Neodymium motor not only sets new standards, it’s coupled with a dual-laminated acrylic foam/fiberglass cone that’s as tough as it is light and rigid. And last but not least, at the heart of this gem is a 4-layer flat-wound Aluminum voice coil surpassing the thermal durability and efficiency of even esoteric edge-wound voice coils. Try not to admire our patented “TI” basket with road-proven rigidity and reliability. As is our patented trade-mark, the Pro-5100 top allows easy servicing whether you are on tour or upgrading a Hollywood studio.Highlights High-temperature low eddy-current stainless-steel voice coil former2+2 ohm dual coil 4-layer flatwound Aluminum wire, 4″ diameter10″ linear dual spider suspension with large integral lead-wires3″ long segmented radial NdFeB (neo) motor for low mass and very high BLFEA designed 3-roll cloth surround for more than 2.5″ peak-to-peak travelField-replaceable top assembly, weight-optimized assemblies thoughoutLarge anti-flux-modulation shorting ringDims – Diam. 18.52″ • Cutout: 16.83″ • Depth: 11.27″ • Weight: 53.4 lbs.
