Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure

@abd1   How are your current speakers setup? If you share their positioning, toe-in and your listening position measurements; as well as your room's dimensions and speaker placement within the room...other owners should be able to give you better (more effective) feedback.

Here's some images/layout of the space. I have some other furniture in the room and a large area rug. I can't reconfigure the space (WAF). I've moved the speakers as wide as possible and as close, forward and back. I get some different results on different tracks but vocals tend to always be left sided. Being this is technically a dining room there is a cut out for hutch, which is where my equipment cabinet is. It's about 8' wide and 1' recessed. I wonder if that is creating some issues in the room, as well as the window area.

David, did I read that you toe your speakers in to cross before the mlp?

@abd1  We are out the door headed to the beach. In Florida for a short break. I'll respond once we are back inside this evening. 

Your layout pics are super helpful. Hopefully, others will offer their perspectives and advice.

FYI dimensions are approximate but pretty close. Picture also depicts two subs but I'm only using 1 right now.
