Hello,
as a quite new Gamma owner I couldn’t find measurements about this speaker. Therefore I made some measurements, maybe the information is useful for somebody.
First I measured impendance in different poti-settings. In my Gamma the „MIN“ position of the LEMIM should be avoided due to different impendance curves between the speakers in this position
First box no.1 with poti in „min“ position (with passive network for the woofer section)
Box no.2 with potis in „min“ position shows a different behaviour between 200-500Hz (with passive network for the woofer section)
Beside that between 9am -3pm the curves a pretty similar between box 1 and 2.
Below some measurements for different poti postions (10 dB scale). Given the results of the impendance measurement I avoid min/max position by only using the potis between 9am -3pm.
LEMIM: Blue 9am, red 12, green 3pm
EMIM: Blue 9am, red 12, green 3pm
EMIT: Blue 9am, red 12, green 3pm
SEMIT: Blue 9am, red 12, green 3pm
Finally a comparison of the woofer section. Active, with SCU at 164Hz, Bass Contour +5/-5, without DIN-cables and with DIN-cables connected (green and blue), which balances upper and lower bass.
Hope that was interesting for you,
Wolfgang
