Mellow speakers for a digital piano


I have been trying to get my digital piano to sound more mellow instead of so sharp / tinny.

What I have been using are Focal CMS40 powered monitors and JBL LSR 305 powered monitors.
I get a nice clear sound but it is too sharp, yet.   I have tried EQ boxes and even that does not do it for me.

I hear piano sounds (internet) from various sources and I long for that sound from my piano.

I wish to find something I can put on a stand behind my piano and at ear level.

I have read things on this site that are encouraging but have no idea if what someone else likes is what I would like.    

Any thoughts ?
