  • Note: Speaker Lab, logarithmic sweeps on a turntable, microphone at 1 m, gated 4.8 ms (reflection-free above about 206 Hz). The bass below the gate's limit: joined from near-field close-ups (woofer and port). Near-wall fix on: a take with a reflection inside its gate is cut before it and filled below its limit from the on-axis model. Known issue - horizontal 120, 240 deg: timed on a reflection stronger than the speaker's own sound (something close behind it); best re-measured. Known issue - vertical 80, 100, 180, 190, 210, 250, 260, 270, 280, 290 deg: timed on a reflection stronger than the speaker's own sound (something close behind it); best re-measured..
