Kaspar LX521 Outdoors (DSP)

6 Channels - On-axis only (0 deg)

Kaspar Reili's LX521 measured outdoors at 1 m on-axis (18-Oct-2022), ungated. Lower mid, upper mid and tweeter captured individually downstream of the active crossover/EQ, plus the full system at three DSP gain profiles. On-axis only - no polar coverage.
