I think that technology already exists, which are the TransAcoustic from Yamaha and Aures from Kawai. They install transducers on the soundboard of real acoustic pianos, which can be used either as regular acoustic pianos or digital pianos (the sound comes from their top samples, channeled to the transducers). I haven't seen a TransAcoustic or Aures yet, but I have done some experiments with large plywood sheets and transducers, and also attached a transducer to the soundboard of a real baby grand piano. With wood, the sound is not directional, like what you get with traditional speakers placed left and right (if you play a digital piano sample using large plywood sheets with transducers and you walk around the room, the sound is the same everywhere, just like a real piano). However, it still sounds digital. I also placed a transducer on a guitar and played back classical guitar music... it still sounded digital, until the guitar strings were energized by the transducer (at certain moments) and then the guitar sounded real. There is a technology called "DML" (Distributed Mode Loudspeaker), which is basically using a thin membrane that vibrates with transducers. It is the same principle behind a soundboard.

@@Instrumental-Coversyou seem to know a lot about this. I hear what your saying. I think Yamaha would definitely kill it if they add the transacustic transducer to the avantgrand pianos, it would completely change the game. I love my Yamaha N1x avantgrand but damn it there’s nothing like the sound that comes from the wood of a real piano. Feels so warm, like it has a soul my piano plays nicely because it has a real grand action but the sound doesn’t connect me to the instrument. It sounds like a speaker.do you think you could connect a transducer to my piano?

@@rinoceronte1 I haven't played a N1X, although I have played the NU1X, N2, and N3X. Yamaha doesn't make their digital/hybrid pianos to be bass prominent... I assume that's what you mean by a "warm" sound. Unless you play a concert grand piano, smaller pianos don't have a lot of bass, and I think Yamaha tries to replicate the sound of smaller pianos. For example, the AvantGrand N3X sounds like a baby grand, meaning it has very little bass despite having 4 woofers facing downward. At least that has been my experience with that model. But if you want to add bass to your piano, I recommend using a small subwoofer (preferably sealed rather than ported for this application) that has a crossover frequency knob and setting it to around 80 Hz. You can connect it to the line out and change the volume manually until you reach a realistic balance with the rest of the speakers. You can't add a transducer to your N1X, since it needs a soundboard to operate. The AvantGrand N3X has a soundboard resonator + transducer placed on the panel behind the music rest. The N2 also has a soundboard resonator. The new Clavinova CLP 775 and CLP 785 have a transducer as well, but they are playing harmonics (high frequencies) to enhance the depth of the sound. A transducer doesn't necessarily make a digital piano sound "warm", if by that we mean more bass prominent. If you want a transducer to play bass frequencies (aka "warm" sound), then you would need to add a soundboard as well as sending bass frequencies to the transducer. Yamaha had the CGP-1000 about 15 years ago: a Clavinova in the shape of a baby grand piano with a soundboard and transducers. But I am not sure that transducers with a soundboard are necessarily superior to the use of an elaborate speaker system. I think both systems can achieve similar results if done properly. I have also experimented with large woofers in open baffle format (15 inches) as well as plywood soundboard +transducer to add bass to the piano, but you need to have a separate amplifier with a subwoofer frequency knob. The bass will be more audiophile as it doesn't energize the room (not a boomy, impactful bass, which is unrealistic for piano sounds), but even a small subwoofer with a gentle touch of bass can be used to increase bass performance.

Jesús, you know your stuff. You should work for Yamaha. I will look into the subwoofer. I wish I could just afford a grand at the moment, as I said I really enjoy the sound and feeling of a grand. Don’t think we will ever achieve that with an electric. But thanks for your help!!! Do you have any recommendations for subwoofer?

@@rinoceronte1 Ha ha, thanks. I prefer an acoustic piano too, even the best digital/hybrid pianos are pretty far from the experience of playing a grand piano. Regarding the subwoofer: any subwoofer with a frequency crossover knob will help, but I just thought of something else... a JBL PartyBox speaker. I have a Yamaha P125a, which has an excellent speaker system for the price, however, it lacks bass. So, I connect it to a JBL PartyBox. That speaker has a very bass-oriented sound (warm sound). You can control the amount of bass that you can add to the piano sound by increasing/decreasing the volume of the JBL speaker. It makes quite a difference. If you don't have a subwoofer already, maybe that speaker is a better option since it is a Bluetooth speaker and you can play music too. I actually use it to play backing tracks I create, then I play the P125a along with it. By the way, you don't want to bypass your N1X speaker system, only add a bit of bass via an external speaker, but keep your piano speakers engaged.
