DIGITAL PIANOS & INTERNAL SPEAKER SYSTEMS - UPDATED REPORT - Jan 1, 2023 | What you need to know before you buy any digital piano! | The top name digital pianos including Casio, Yamaha, Korg, Kawai, and Roland
INTRODUCTION
Digital Pianos are very popular these days and there are many to choose from in a variety of brands. Each model has its own specifications and they can vary from one digital piano to another. You might see various descriptive words in their specifications such as number of keys, key action type, weighted keys, unweighted keys, touch sensitivity, pedals, functions, display, polyphony, voices, tone generation, reverb, layer, spilt, songs, recording, playback, transpose, storage, MIDI, USB, Bluetooth, connectivity, and many other specs in the various digital pianos.
But a very important specification that many shoppers tend to overlook is the internal speaker system. Namely, speaker size, amount of speakers, quality of speakers, placement of internal speakers, do they have passive bass speaker ports, good amplification power, and how many amplifiers are in that digital piano vs how many speakers?
In other words, based on our experience with all of the digital pianos out there, without a great internal internal speaker system inside the piano, the "piano sound engine" (instrument sounds) and the rest of the sound functions and features just will not sound good.
PORTABLE "STAGE" DIGITAL PIANOS
There are some digital pianos that are called portable "stage" digital pianos. They are mostly used by musicians or other players who want a portable instrument
without internal speakers because they are either playing music on stage at some venue which has their own external speaker system and external monitors or that musician only wants to use
external speakers for some other reason such as having a sound guy at an external mixing board running sound remotely so that he can adjust volumes, etc for the audience to hear it good... like in a big stadium, concert hall, church, or other large venues.
Having a "stage" digital piano does not necessarily make that piano better than other digital pianos which have internal speakers, but a stage type digital piano may have certain functions or features on it that could be more appealing to that particular player or pro musician that digital pianos
with internal speaker systems do not have.
The person playing that stage type digital piano will also need to hear it up close near the piano, so they would also need stage monitors putting out the sound next to them so they can hear it better. For most people portable playing digital pianos recreationally who do not play regularly in big venues, stage digital pianos are generally not necessary and a regular portable digital piano with an internal speaker system is the way to go.
An exception to that is if you have a home or pro recording studio and you want many "pro" features, functions, and sounds in the digital piano for recording purposes that a regular portable digital piano may not have.
Also, in a home or pro recording studio you will likely already have external monitors (2 good monitors can easily cost $700 on up) that would take care of all the sound in that studio including coming from that digital piano/keyboard. At that point a pro quality "stage" digital piano could be the best option for you and then the importance for a good internal speaker system in a digital piano would be irrelevant.
PORTABLE "SELF CONTAINED" DIGITAL PIANOS
The more popular portable digital pianos have an internal speaker system, unlike the portable the stage digital pianos that have no internal speakers. When a portable digital piano has an internal speaker system then they are referred to as being "self-contained." These portable "self-contained" digital pianos are more practical in my opinion because you can hear it through its own speaker system rather than always connecting to an external sound system.
These portable digital pianos with internal speaker systems are very popular for a variety of reason including portability, being able to fit into smaller spaces, and sometimes giving you a "bigger bang for the buck" as compared to furniture cabinet digital piano in the same price range.
Since we are focusing on internal speaker systems in this report, these portable digital piano can actually sound great and much better than you might expect for the smaller sizes they have. Also, portable digital pianos usually can come with an optional furniture type stand and triple pedal bar at an additional cost.
Internal portable speaker systems usually have either 2 speakers, 4 speakers, 2 amplifiers, or 4 amplifiers and can have low power amps below 10 watts total power going all the way up to a big 60 watts of power depending on the price range of that piano. With that in mind you really have to be careful when purchasing a portable digital piano and be sure you are getting a good internal speaker system that will produce great sound without sounding tinny, artificial, and toy-like.
HOME CABINET DIGITAL PIANOS
But for home use in a cabinet digital piano, generally speaking, the furniture cabinet digital piano you would want to purchase should have its own internal speaker system that is powerful enough and has enough quality to provide you with a very full and resonant piano sound, without getting distortion. That internal speaker system needs to be good for your playing skills and musical goals as well as for the room you are putting it in. It is important to have good, resonant piano sound and that's why it is important to look at the digital piano specification when it comes to its speakers and amplifiers. It doesn't matter what size or the cost of the digital piano you want to get. Make sure the sound is going to be heard in a way that you will not regret.
If the speaker system is underpowered then the piano and other instruments and features in it could sound somewhat anemic and artificial when you play your music. Also the piano may not have enough power and/or presence to fill up the room that you are playing in as well as maybe not having good bass response. Watching demo videos on-line of digital pianos will not let you hear the true sound coming through the speakers because of the way those recordings are done.
The only real way to know if a digital piano will sound good, sound, full, provide good bass response, and not sound tinny or artificial in your room is to see and play those pianos in person or to ask us! We can tell you because we have played all these pianos in various room sizes.
WHAT DO YOU REALLY NEED?
Therefore, it's important to know what speaker system is in the digital piano you are looking at and how much do you really want and need in terms of speaker quality, size, and power. Overall it can be a somewhat confusing subject. Regardless, normally the more you pay for a digital piano the better the internal speaker system gets.
This is true not only for the number of speakers in that model but also for the size and quality of those speakers, the way the speakers are mounted into the cabinet, and the amount, quality, and power of the amplifiers that are driving those speakers.
As an example, in the new low end Yamaha Arius model called the YDP-105 which sells for $1100, it has just 2 amplifiers with a total of 12 watts of power going through 2 speakers measuring 4.7" each. For $1100 that speaker system is much too small in my opinion. Yamaha could have done much better, especially for that higher price.
However, in the Yamaha Clavinova CLP-745 digital piano, which sells for $3700, that model has 4 amplifiers with a total of 200 watts going through 4 speakers. Two of those speakers in the CLP-745 measure 6.2" each to help carry the bass frequencies, and the other 2
speakers measuring 3.1" each help carry the higher end treble frequencies. The speakers and amps are also higher quality and they have much better internal placement in the Clavinova CLP-745.
When you have more and better speakers and more and better amplification in a digital piano, along with better speaker placement in that model, it is going to sound more like a real piano. Also, that upgraded sound system will likely improve the frequency response and dynamics of the piano sound and you'll also likely get a lot more bass response, which is a good thing.
CHOOSING INTERNAL SPEAKER SYSTEMS
So with all that being said, here's my rule of thumb for a better sound experience in a digital piano. In a portable digital piano, make sure it has at least 16 watts of power going through a minimum of two 4" speakers coming out near and/or on the top of the piano pointing towards you.
In a furniture cabinet digital piano make sure you have at least a minimum total of 40 watts of amplification power going through at least two 4.7" speakers, and if possible, two smaller tweeter speakers to help carry the high end frequencies better. Some portable digital pianos I have played have 40 watts or more power in them, so they are very powerful and sound great with good bass response.
CHOOSING AMPLIFIER POWER
The thing that more amplifier power (wattage) does in a digital piano, especially in a furniture cabinet digital piano, is allow that piano to project its piano sound further with better tone and clarity and generally much better bass response as well. Furniture cabinet digital pianos that have just 12 or 16 watts of power are underpowered in my opinion and I have played those digital pianos and personally experienced them, and generally don't like them.
They typically sound anemic with low power and you have to turn up the master volume to maximum to get a better sound out of them, but then you can typically will get some distortion and they don't sound full or resonant most of the time.
The more speakers, amplifiers, and power in a digital piano, generally the better off you will be. There are some caveats to that equation, however. Let's say a digital piano has slightly lower amplifier wattage power as compared to another digital piano in the same price range. But maybe that piano has more speakers and also better speakers in it.
If the amplifier wattage difference between the 2 models is not that much, then the extra speakers and quality of the speakers and amps inside could make up for and surpass the slightly less amp wattage power. But it also depends on how big of an area in your home or venue you are trying to cover. You may not need that much power or bigger speaker size, but it can't hurt to have it, just in case. So just keep that in mind when making a decision on how many speakers in the piano that you'll want, how many power amps will be necessary, and how much overall power will work best for your situation.
SPEAKER POSITION & SOUND DIRECTION
Also, the direction in which the internal speakers are pointing can have a lot to do with how you hear the sound and the impact those directional speakers will have on your piano playing experience. If the speakers are under the piano pointing down to the floor, then that would not be as good as the speakers pointing up along with speakers pointing towards you. A perfect example of 4 speakers with each pair pointing in different directions along with 4 separate amplifiers powering each speaker would be the
Korg G1 Air at $1999.
This Korg model has an internal speaker system at $1999 that surpasses many digital pianos up to about $3500. So when it comes to "price" in a digital piano, it's still a relative thing when it has to do with the internal speaker system. A higher price in a digital piano does not always equate to a better internal speaker system over a lower price digital piano, although in many cases it does. You'll just need to contact us when you are doing your "shopping" so that you make the right decision.
If the speakers in a digital piano are pointing upwards towards your ears or if there are 4 speakers in the piano (perhaps they are different sizes to handle different frequencies) with 2 pointing towards you and 2 pointing upward or even downward in that case, then that will make the sound dispersion more omni-directional which can be a very good thing.
So there's a lot that goes into the internal speaker system including the quality of the components themselves and the impact it can have on what you hear when playing the digital piano.
DIGITAL PIANO SPEAKER SYSTEM CHART
Below is chart of nearly all the top current 88-key digital pianos under $8000 that have internal speaker systems. I picked the price range under $8000 because that will cover most models out there from the top brands. There are a few other models above $8000 so if you want that info then please contact us. The prices listed for the upright or portable style digital pianos are in the
matte finishes, although some of them are available in
polished ebony and polished white finishes for
more money.
The baby grand style models by default come in the polished ebony finish. I am leaving out the secondary brands (Williams, Suzuki, Artesia, Donner, etc) that have relatively poor key actions, poor playability, and overall a noticeably more artificial piano playing experience as compared to these top 5 brands below.
