What is tough about speaker measurement is the power handling in relation to frequency. For most music the power divide is around 400 Hz, so you need to devote as much power resources above 400 Hz as below. This seldom happens in three way designs and in my view it is a significant problem and defect. So here we have a typical three way crossed over about an octave below the power divide. There are two 8" drivers crossed certainly significantly below the power divide and only one 6" mid above, given that the tweeter is well above the power divide. This all too common design choice severely limits a speaker's ability to reproduce a full symphony orchestra, choral music or pipe organ. I suspect this is not so serious with music from the 'pop' culture but it is a serious shortcoming for reproducing large orchestras, especially with chorus and opera. When you have a large orchestra and a huge opera chorus, like the Met opera chorus, the vast majority of speakers, even very expensive ones fall seriously short, with serious dynamic compression or worse.
This speaker I fear is another offender among many. There is a reason I put resources where I do in my speaker designs, and they are essential design choices.
I think every speaker designer should have a recording production program on their computers. I use WaveLab and it would show any designer that looked at it on the screen where they need to devote resources. This is a persisting chronic shortcoming the needs attention from speaker designers.
