Tried this with a Yamaha CVP-701 (the speakers are absolute crapÂ at reproducing anythingÂ lower than one octave below middle C - downward facing speakers make it sound like the speakers are under a blanket). The sub only made the sound more boomy.Â Added a pair of small JBL bookshelf speakers (mixed with the internal sound system) and saw a MASSIVE improvement but still too boomy. Dropped the sub and added replaced the bookshelf speakers with a pair of Yamaha HS7 studio monitors (much flatter frequency response) and the sound is glorious!
I suspect even the HS5's would add a special something to your setup if the 7's were too big. A sub is really only intended for sub bass and it is extremely difficult to control these frequencies unless you have a good room with well designed treatments. That said, only a sub is going to give you that "kick in the guts" feeling like playing at aÂ 9 foot concert grand which can be a lot of fun (for a while).
BTW: I'm a huge fan of the Yamaha HS series of studio monitors. I use the HS8s forÂ aÂ Fractal Audio AX8 guitar processor andÂ the response is unbelievably flat (you hear exactly what's going in).Â There are better monitors out there but nothing comes close at the price point!Â Flat response is VERY important especially with piano. Different speaker/amp combinationsÂ tend to over/under hyped different frequencies making the keyboard sound uneven. I suspect that a lot of the complaints that people have regarding some of the piano sample libraries has more to do with their sound reinforcement (speakers/headphones) than the actual libraries.
