O6 Top Speaker Protection:
File: "o6Top_protect_20210720_120hpf_pb6.47.0_17.5dB_withRtrace_125C_fastRL.bin"
Phone file: /vendor/firmware/cs35l41-dsp1-spk-prot.bin
Sha1sum: 033d5ad6d6be86849d74fe641c575e50425cd8c0 o6Top_protect_20210720_120hpf_pb6.47.0_17.5dB_withRtrace_125C_fastRL.bin
Changes: Decreased TMAX for 5degC margin at peak, increased thermal rate limiter attack to 0ms (fastest possible)
Tests - Protection: Passed XMAX/TMAX testing
Tests - Acoustic: Passed acoustic impact testing (no much change from POR tuning in FR, reduced distortion)
Tests - Listening: Coupled w/ bottom speaker - Can hear slight change in color on compressed chorus (negative), but brings out warmth slightly (positive), and slight impact to loudness because of sharpness delta (negative)
