RE: Very effective demo




By using high rate crossovers, the driver frequency overlap is much less and out of band signals to the individual drive foils is lower. Since the 3 drive foils are on one mylar diaphragm, taking excursion out of all foils lowers distortion for the entire planar speaker.

Just correcting the woofer foil output to be at the same output level as the tweeter/supertweeter foils drops the diaphragm excursion.

Crossover points are the same as I am correcting the original speaker with passive crossover installed in this demo. Not a direct drive setup as I did for CAF2023 with the MG10/QR speakers and disconnected the passive crossover to run each drive coil/foil to new 5-way connectors on the plate.

This is a third party on-axis measurement of the LRS speaker model. I do not see that as a flat on-axis response. I used this as the basis for the speaker correction for the LRS at CAF2024 that I then integrated to the two 1x12 OB subs.
