  • 109dB SPL 1W/1m average sensitivity
  • 1inch exit on 1 3/8” screw-in type
  • 1 inch voice coil diameter
  • 40 W program power handling
  • Rugged phenolic diaphragm
  • Usable in two way or multi-way system
The HD110 is a HF unit suitable for compact size two and three way lightweight systems. It will deliver an unmatched combination of extended linear frequency response and very high efficiency. With a throat exit of 1 inch, the HD110 is developed to match all 1-3/8” screw-in type horns.
The phenolic diaphragm assembly, with its 1 inch edge-wound aluminum voice coil, is capable to handle up to 40W continuous program power for temperature range up to 250°C.
Computer Aided Finite Element Analysis and extensive testing were used to obtain phase plug shape made in high pressure injectionmolded polypropylene foam, designed to assuring maximum strength. Final result is a smooth coherent wavefront in the horn entrance, high thermal stability and manufacturing consistency.
The HD110 compact size and lightweight ceramic magnet assembly is designed to obtain 16KGauss in the gap.
