Beyma 10BR60 for OB?

[DarkOne]

Gents,
after reading many good words on open baffle sound here on the forums I decided to give it a try.
Beyma 10BR60 looks like very good driver for open baffle with enough displacement volume, smooth frequency response, Qts=0.47 and its cheap in my country (<$70). My first thoughts are to use 3 pairs. One pair as midbass and 2 pairs as woofer with EQ. Then maybe just tweeter with waveguide is enough to fill up the highs.
Alternative could be two 10BR60 as woofer, one 8BR40 as midbass and a tweeter (with waveguide).
This is gonna be my first OB project. It's going to be used in 16-20m2 room. Playing mostly rock music not too loud.

Is it good choice of drivers, or I should look for other ones?
Every opinion is welcome.

Thanks in advance
