Topic: Casio PX-870 - use DP speakers for Pianoteq output USB? - Windows 11

Hello, I'd like to be able to use my Casio PX-870 as the usb/midi keyboard, then use the same piano's speakers to output the pianoteq audio.  However, it doesn't seem to be an option for the audio output, only input.

I read another old post about someone being able to do this with their Casio px-780, but my pc doesn't recognize any outputs from my casio px-870.  Windows 11, the inputs show up for pianoteq but there's no output option besides the speakers, and digital out (which doesn't go to anything).

The reason why this matters is because 1. money is limited, 2. space is limited.  The speakers on the piano may output better quality than the old PC speakers I have which are currently outputting pianoteq, and I'm trying to find alternatives to what (so far) have seemed like underwhelming monitors like the Adam Audio T7V that I've trialed, or the much more expensive alternatives. 

Any thoughts how I can get this to show (or is it possible)?

Alternately, any better choices besides the Adam studio monitor T7V for the purpose?

Hi, I understand your idea and why you are tyring to do this because I also had used my Casio PX-350M's internal speakers as output device.

So, I have checked out the user manual of Casio PX-870. Unfortunately, it looks like PX-870 does not have Line-in or Audio-in port which is necessary to play real time Pianoteq sound through PX-870's internal speakers.

Casio PX-780 has Line-in port, so if you connect PX-780 to PC and play piano, then you can hear the sound coming from PC.

I'm sorry.

Could you tell us how you positioned the loudspeakers. How far apart. Were the tweeters pointed towards your ears at ear height?

Was one  speaker close to a side wall or were both a  good distance from side walls?

Trying to understand how the monitors would be worse than the loudspeakers built into the piano.

Sometimes some users have expressed a preference for the sound coming from the piano's own loudspeakers because the sound is that much better integrated than any external loudspeakers. However correctly positioned the fidelity should be far superior from the studio monitors.

Re: Casio PX-870 - use DP speakers for Pianoteq output USB? - Windows 11

My current PC speaker setup is limited (very old creative labs/cambridge soundworks henry kloss 2.1 white tweeters with sub below), but the sound is pretty good for many uses.  It even sounds good to my ears for pianoteq, but the tweeters start popping when the volume kicks higher, so I have to keep the volume relatively low.

For my purposes for now, I would be satisfied with the good-enough speakers on my Casio PX-870.  It's disappointing to find out that there's no audio-in type option on my piano to use it as receiving speakers.

When I experimented with the Adam T5V and T7V (as well as 8" KRK rokits and a Focal alpha evo 65) at Sam Ash, I made sure to be approximately on-level with the speakers and experimented with upward and downward positioning.  The focal sounded roughly the best, but $450 per speaker is not within my budget.

I am not an audiophile, but I do want to be able to distinctly hear at least some of the nuances that pianoteq generates, and non-muddy reproduction is important to me.  Ironically, my old speakers sound every bit as good to my ears as the speakers they had there.  Maybe the subwoofer on the floor adds depth and presence, but I can identify each note clearly with my very old PC speakers as I listen to myself playing.
