- Frequency deviation is 3.8dB over the same frequency range.
- Tonality (Preference) Score
- Tonality (Preference) Score is 4.84
and would be 6.52 with a
perfect subwoofer.

and would be 6.52 with a
perfect subwoofer.
- Note: measured with broadband noise at 2m. DUT is a DDQ12 with a DDQ Sub 212. It is unclear to me if the measurements are correct.
LD Systems DDQ12+Sub is an active liveportable that cost around 3000 USD each.
