Mellow speakers for a digital piano

No, he needs to throw a lot of money at a hi-fi solution, tube amps and such. Definitely needs some shiny new gear from one of the resident dealers. There’s no way any pro audio gear will solve the problem.

Or you could just try turning your speakers outward at a 45 degree angle so you don't get the full brunt of the highs.  That would certainly be a cost-effective solution.

Wow .... now we are getting somewhere ... 

These homeopathic/Rube-Goldberg solutions may be just what I need.

LOL ....

You can be sure I will try them all.

Desperate times and all ...

Yamaha NX-N500. Lovely sound, smooth, reminds me of Era/Peachtree D4. I have Era D4 hooked up to Yamaha RX-A1060 in my sunroom and NX-N500 in my kitchen. Love them both. Nice but not boomy bass for the size.

About $500, amplification included, plus a really nice wireless music solution. I take them with me on vacations.

If this is just for home use, I would start with a tube amp of about 30 watts, like a Dynaco ST-70 or the like, and find a set of speakers that are easy to drive so that 30 watts means something.

My JBL JRX215 speakers that I use for my keyboard rig are 8 ohms and 97 db; they are easily driven by a 30 watt tube amp. On stage I use 500 watts per channel, but there is no need for that at home. You can find them for $300 each on ebay. They are not the last word in resolution, but they sound surprisingly good with a decent signal. Not much output below 40Hz.

You might also consider a set of JBL L-100s...

You might want to process the sound a bit. I would not use a mixer, but I would consider a digital reverb like this one: http://www.alesis.com/products/legacy/nanoverb2
