The Helical Approach
B&C has a reputation for performance, by turning the limits of traditional compression driver design on their head. HLX™ : Compression driver efficiency in miniature. The HLX™ phase plug (US and EU Patents Pending) has a central channel that is twisted, like DNA, to gain the length required to match the outer channels. This technique works with standard, cost-effective injection mold tooling and plastics by rotating the inner die along a screw profile. The convex dome design, so achieved, has a number of significant cost and performance advantages.
➔ Minimized diameter, weight, and cost
➔ lncreased diaphragm area
➔ Low, ~1kHz Crossover point
➔ Reduced distortion, especially intermodulation distortion
➔ More efficient magnetic flux use
