    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
