I ment the volume knob behind the sub. And no, I'm not at all even experienced hobbyist when it comes to speakers. But anyways, this is what I got turning the volume way up, crossover at max. The highest measurement can be discarded: I'm not an expert but it had some weird noise that shouldn't be there.Start perhaps with definition of "25%"....then we can see if you're simply insufficient.
I think the reviewer I mentioned had a smaller room because these results seem worse. These are 2,25m from the listening position.
But I now agree that the dual 9"s wouldn't do it for movies in a larger room or at louder volume. Might be enough for many situations.
