The extra woofer and tweeter in the VP150 increases the output per watt, increases the maximum spl, and raises the power handling level. As a result the VP150 can play very clean, loud, and acurate. The driver array in the VP150 also adds to the sound stage.
You can certainly use the large setting for the VP150. You should try both settings to see what works best in your room.
We decided against porting the center channels to keep the power handling as high as possible.
