Leading Edge Technology for Loudspeaker Crossover Networks
High-technology laminating makes it possible to manufacture inductors from high purity copper or silver foil wound onto a Lexan polycarbonate tube. Foil inductors are mounted by means of a single polycarbonate screw through the central bore, or a silicone elastomer, or a hot-melt adhesive.
· Negligible skin effect below 100 kHz many orders of magnitude below conventional wire-wound types.
· High winding tension and vacuum fusing of faces provides high dimensional stability, effectively locking the conductors in place. Wire-wound inductors, which allow relative motion of conductors due to electromagnetic forces, will exhibit FM distortion by the process of reactance modulation.
· Flat inductive reactance from 5 Hz to 50 kHz.
· No saturation distortion due to air-core design.
· Inductors contain no magnetic materials.
· Reduced power loss.
· Highest space factor (ratio of conductor cross area to total cross-section) means lower DC resistance within comparable dimensions. Negligible power loss due to skin-effect.
· Extremely low stored charge.
· Cool operation even during prolonged high output power operation.
· The high space factor and winding density results in improved heat dissipation.
Since we introduced our Air Core Inductors in 1997 they have become standard fixtures in many of the world’s finest speakers, and thousands of audiophiles have improved their sound by personally upgrading their crossover circuits with our products.
