How can I tell if a certain desktop speaker will emphasize voice?

[mrmojo]

I have the audioengine a2 speaker, and bought the iLoud micro speaker.

I noticed that the audioengine a2 emphasizes voices way better in rock, pop and hip hop compared to other speakers like the iloud micro speakers, kanto yu4.

Why does the audioengine a2 have the capability to emphasize voice way better than these other speakers?

I like other things about some of these speakers more than the a2 (the iloud micro have way better bass than the a2) , but how do i tell from any of the speaker specs if voice will be emphasized or not?

Because of its frequency response:

That relative bump at 1-5kHz will make voices sound clearer.

Here's the frequency response of the iLoud Micro:

As you can see, there's no such emphasis on the Micro.

No graphs for the YU4 unfortunately, but it'll measure similarly flat most likely.
