  1. ? Is a Patent

  2. Planar Waveguides are designed as plane Waveguide- Horns with a Helmholtz-Resonator as the motor

  3. Advantages

  4. Advantages F18, F17, V18, V28, alpha B3 • Extremely High Efficiency • Outstanding Directivity • Long Throw Capability • Very Low Distortion • High Operating Safety

  5. F18, V18, V28, alpha B3 = 1. higher SPL 6 dB

  6. F18, V18, V28, alpha B3 6dB higher SPL (at same voltage) Means: In order to achieve the SPL of a F18PWH one would need to feed 4 times the amplifier power into a conventional vented cabinet !!!

  7. F 18 PWH Reference Amping Power 100 W needed 400 W 4 times the amplifier power Same SPL

  8. F 18 PWH Reference needed 500 W 2000 W Amping Power 4 times the amplifier power Loading 4 times the power into a conventional vented cabinet equipped with the same speaker would result in... Same SPL

  9. There is no speaker to stand 2000 Watts available !

  10. F18 Frequency Response on axis:

  11. F18, F17, V18, V28, alpha B3 = 2. Low Frequency Directivity

  12. F 18 PWH Characteristics of a conventional direct radiating vented cabinet

  13. F 18 PWH Unique and Outstanding Directivity of Planar Waveguide Horns

  14. F18, F17, V18, V28, alpha B3 Low Frequency Directivity • Means: • Less "wood" for longthrow applications. • No "Bass-Overhang" on Stage.

  15. F18, F17, V18, V28, alpha B3 = 3. Significantly reduced speaker excursion

  16. F18, F17, V18, V28, alpha B3 Makes for: Lower Distortion Increased Lifetime More Headroom x Significantly reduced Speaker Excursion

  17. F18, F17, V18, V28, alpha B3 4. No Magic !
