Hi, I still have some time of being able to make noise before living in a flat, so wouldn't mind to make use of it and increase a bit the volume of my CA65! grin

Something I was considering is to use one of those speaker bars or maybe even one of those home sound systems with several speakers to put in different places. I wouldn't like to put big monitors on top of the piano.

I see that they normally come with the peel wires, not with a jack. So I wonder if they can be adapted to connect to the audio jack?

Has anybody tried this?

Are you looking to just get it louder? I thought the CA65 was pretty loud. If you are trying to make it sound like a piano in the room, it will be difficult because you are working with a stereo signal. At best it's probably just going to sound like a mic'ed piano playing through loudspeakers/monitors.

They have cables that are 1/4inch on one end and RCA on the other.

You could also add a sub with a filter if you just want more rumble to your low end.

The piano outputs at Line level, which means it's carrying the signal, but not the power to drive speakers. So you need to attach to either an amplifier or powered speakers (i.e. speakers with amplifiers built in).

I would give a cheap 2.1 system a go...

Most of those speaker bars have everything and I think OP mentioned the other option was to run it through his sound system.

The speakers that OP mentions with "peel wires" (I assume she means stripped copper) are certainly meant for plugging into an amplifier, and attaching them to the piano directly via a jack will not work.

I see. Yeah, if he is looking to connect directly to speakers that come with a sound system, he certainly has to go through the system. It's too bad most home DPs don't have digital outs.

I meant something to connect directly to the digital through its audio jack preferably. It can be powered to the mains, that is not a problem.

But aesthetically I would prefer not to have large monitors on top of the digital.

I was thinking in something like a speaker bar or one of those speaker systems with 3 or even 5 small speakers to place around the room. But I only saw them with the stripped copper (thanks lotatu, I had no idea of how to say that!) like the ones I have for my music system.

I would not run it through a multichannel system. The Kawai DPs use a stereo signal and trying to run that through a DSP for multichannel output is going to give you mush.

Stick with a stereo signal. Use the 1/4 outs from the Kawai and the RCA inputs on a soundbar or preamp/receiver. You aren't going to get a digital signal from the Kawai.

I wouldn't put speakers on top of the Kawai either. Just put them on either side.

Also, don't blow your ears out. The CA65 is pretty loud at full volume from the playing position.

I had thought of using a sound bar for a DP cabinet that I made, but ended up using a computer sound system (with a subwoofer). Works very well! The subwoofer adds a nice presence without necessarily being too loud, and the other speakers are small enough to make them unobtrusive.

Thank you guys for your help! I'll look for something decent but not too obvious.

Hi,

I have a Kawai CA-63. I hooked up a Sherbourne 2x65w audiophile amp from one of the earphone jacks and then then ran amp output to a pair Def Tech SM 45's. I do have them on top of the piano. If you adjust the spacing and angle of the speakers you don't get that "in your face" sound.

The sound is a HUGE improvement. It sounds quite realistic. I do not run the volume very loud. On the piano, I run about 25% out and on the amp I run about 60% out.

I have been very happy with the set up.

So what exactly don't you like about the sound your current setup makes, that makes you want to add more speakers? I'm not saying it's right or wrong, just curious if you feel the on-board speakers are insufficient somehow.

FWIW (there's some guesswork, here) --

"Peel wires" (wires from which insulation has been stripped?) are usually used to connect _unamplified_ loudspeakers to the output of an amplifier.

Speakers which have their own built-in amplifiers ("powered speakers", "amplified speakers", "powered monitors") usually have _plugs_ at the ends of their input wires.

Those plugs are designed to plug into "line-level" (rather low voltage, around 1 volt, low-power) jacks.

If you pug unpowered loudspeakers into a "line-level" jack (by putting plugs onto the end of the wires):

. . . a) you won't get much sound out;

. . . b) you might damage the circuitry of the "line-level"
. . . amplifier.

Your DP has an amplifier that was designed to drive _its own loudspeakers_, and no more than that. Adding additional _unpowered_ speakers will probably require digging into the DP's circuits, and probably won't give you more volume than you already have.

If you want more volume, you need powered speakers, as suggested above. They'll plug into either a "line out" jack, or a headphone jack, on the DP.
