    HLX Series - 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 Patent #12149906) 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

    • Very Compact 69 mm diameter
    • 40 W continuous program power capacity
    • 1" horn throat diameter
    • 44 mm (1.7 in) aluminium voice coil
