On my VP150 I noticed that if I move from the center of my listening area either to the left or to the right, the sound gets weaker. Meaning the speaker output is directed towards the center of the listening area only.

I am wondering if this could be improved if the front of the speaker design is changed to a slight arc where the configuration is MTMTM instead of a flat front with TMMMT. In this arc design the sound should remain the same even if the listener is on the left or the right of the sweet spot because the drivers would be directed towards a wider angle of listening area.

If this is technically not viable or really unsound, please forgive my ignorance. I am not a sound techie but just a listener looking for a better sound.
