hi keith- have the active rev's arrived yet?
i'm finally getting my helsinki's dialed in,
and this dipole bass is pretty tight, articulate, and when need be, rather
slammin'.
it not only does the usual suspects of up-right and electric bass justice,
but kaiju mayhem, e.g., godzilla (2014), as well.
reminds me of the Tact 2.2x room-corrected bass i'd get back in the 00's.
this page was really helpful in understanding dipole set-up-
https://www.hifizine.com/2012/03/on-dipole-subwoofer-placement/
here's an interesting bit from there-
"As explained by John Kreskovsky in the technical article
Dipole woofer on axis response in relation to listening distance, the 6 dB per octave drop in output of a dipole as frequency decreases (ed- which i believe the active revolutions compensate for) will continue to DC only as the distance from the dipole approaches infinity. At realistic distances, the low-frequency response of the dipole flattens out at a frequency
determined by the distance. In other words:
there is more low bass the closer the dipole is to the listener.
To measure this, I positioned a test dipole panel on an outside deck adjoining the house. The test panel is a relatively small flat panel of approximately 36 by 54 cm, housing a 12″ woofer with the woofer center 22 cm from the floor.
Figure 1 shows the measured responses at distances of 0.25, 0.5, 1, 2, and 4 meters.
Figure 1. Response vs distance to dipole subwoofer at 0.25 (red),
0.5 (green), 1.0 (blue), 2.0 (orange), and 4.0 (mauve) meters."
pulling the helsinki's away from the back wall, which in effect, moved them closer to your
humble listener, really helped turn these into (or at least, get closer to) the full-range speakers
they were advertised to be, "35Hz -6dB".
looking forward to what you find with the arrival/listening of the active rev's.
edit: away from the back wall, closer to the listening position, and angled nicely...
