Just my phone to check the frequencies.
If you play loud, speakers will distort. So it's level dependent.

REW (5.19) can show THD (Total Harmonic Distortion) together with Fundamental (the received sweep) and Noise floor.

You can run a couple of sweeps at different monitor level and see what it looks like.

The Sub 12 manual says (around) 1% THD @ 60Hz level: (?) SPL
and max 115dB.

Is Adam SUB 12 a bad sub? Hmm
That's opinion.
Is Peugeot a bad car?



PS I'm not a subwoofer expert.
