Mellow speakers for a digital piano

Funny you should mention "infinite options" .....

I was just going to respond about the various options now beginning to sound like there is no reliable option ... only what various users have experienced and were happy with.

I absolutely appreciate any and all responses .... that is what I came here for .... but I am now reluctant to dive in to any one of them as it sounds like it may not give me that "final solution" I am striving for.

So ... now I have decided to cut my losses and take a partial bit of advice from one of the responders.   I will order a small mixer and put it in the sound chain I already have and see what happens.

Maybe I can shape the sound enough to get out of this funk.

Thanks for all the help.

Any more responses are still welcome.  I will read them and add them to my list of "options for later" as this problem never seems to go away for good.

I have JBL 305's in one of my studio rooms and they do digital pianos just find. They have a softer upper end than the Revels in my main room. I suspect it's the samples your piano is playing and not the monitors.

This is just the issue. The gear I recommended is solely based on what I've heard and what I believe might meet your needs in terms of tone. However, the MD rep made a valid point. Some home audio gear doesn't play well with instruments. Your best bet might be to take your speakers down to a Guitar Center or some other pro audio shop and see of they'll facilitate some comparisons with their monitors. I have yet to encounter a powered studio monitor that doesn't have an irritating top end, but they could exist somewhere.

In the meantime, you might try placing a piece of tissue paper in front of the tweeters of your current monitors. Not on the tweeter, but stretched across the opening in the baffle. You might be surprised by the results.

Good luck.

I think Atmosphere was the qualified response that makes sense.
    Why not purchase a Pre amp from Atmosphere.
 You are looking for complete integrateds and confused Ralph would get it sorted for you
  I have always thought they sound nice.

Note that you can "mellow" sound with EQ…on a mixer…generally any mixer.
