I just had a look and paid great attention to the SPL/W

USD Y-210 10" Subwoofer
Model Y-210/4 Y-210/4d Y-210/6d
Re Ohm 3.2
6.4 / 1.6 8.8 / 2.2
Vas 27.9 27.8
27.9
Fs Hz 32.1
34.6 33.9
Qts 0.37
0.42 0.50
Qes 0.39 0.46 0.55
Qms 5.84 5.72 5.94

SPLo 87.4 dB 87.5 dB 87.4 dB

Couldn't disagree looking at the spec I would expext them to sound good in
the correct enviroment.
