Audio System info?

Hey All,
I've just joined the club, quite pleased to find you folks.

I'm driving an '07 Sport Eos with the Standard Audio System, and would like to replace/add speakers into the Dynaudio positions.

I'm wondering if anyone knows the dimensions of the Dynaudio Speaker set?

I bought the Bentley DVD ROM for the Eos, and while it explains speaker replacement, it's got nothing on sizing.

Thanks for any help.
