Ill give it a try later using my PC and using Bluestack which is a android emulator for PC.
i don't think that the app actually measures the correction that it applies, for any speaker, and there isn't any measurement-only functionality, so that you could check what the app claimed that it did.
you need to use rew and a mike, if you want to get serious about this.
i think that your original question was, does audyssey tweak the bass curve, and i can tell you that based on pre/post measurements with rew, that audyssey does in fact work from at least 20hz up.
these are measurements: 1)rew before, 2)rew after, 3)audyssey app data(opened in the ratbuddyssey pc app).
you can see that audyssey did make a difference, in the rew comparison, beyond that we mainly care about the 38hz/95hz nulls being roughly similar in both rew and the audyssey app.
so what is wrong here? the biggest problem by far is that rew shows heavy roll-off after 100hz, in both pre/post measurements, while the audyssey app doesn't show that at all... not sure what to attribute that difference to.
