Hello everybody,

I would like to know which speaker would you choose for front left & right in a 7.1.4 configuration where all other ear level speakers are es15 (surrounds and surround backs) and a es30 center, another es15 or a bigger es20 pair? What benefits if any would the 20s have vs the 15s?

They will be used for movies and music always along a subwoofer.

Thank you in advance.
