HK Onyx Studio 7 - frequency response measurements (Patreon)

Before finishing my first video I managed to prepare some measurements of the Onyx Studio 7. In AC-power it gets 3.5dB more loudness compared  to battery mode. The sound itself does not change regardless if played from battery or AC-power. I also did some off-axis measurements (measuring just the left channel to avoid intereference of both tweeters), and I think it's visible that dispersion has improved a lot compared to the mono Studio 6 and Studio 5.

Although when putting the Studio 7 measurements against the predecessors, it would appear as if the Studio 7 reduced bass way more and couldn't play as loud as the old versions. I cannot say for sure if this is not just some measurement error, as I don't remember which gain I used for the testsignal back then, but I from what I could hear so far, I really assume that the old versions could retain more bass at high levels. It could be interesting to get a Studio 6 again, just to put both side by side and verify this.

Also visible from the unsmoothened measurements is that the passive radiators seems to get out of control at around 90hz, there were some severe side noises when playing the test signals, although I didn't notice any issue with music so far.
