Simulation of the segmented ESL element with esl-seg-ui from Edo Hulsebos, Holland.
All simulation data should be in line with information in Schematics and Specifications.
The simulation illustrates:
- A linear (+/-1 dB) on axis frequency response from 200 Hz and up.
- The small drop of 1-2 dB from 300 Hz to 20 kHz is deliberate and in line with recommended house curves, see Resources.
- An sensitivity of 83 dB at 1m.
- A wide dispersion with flat response up til 15,000 Hz at +/- 15 degrees.
We find that the speaker is close to a perfect line source from 200 Hz and up. A very satisfying result.
