I have a Yamaha CP-300 which I like very much. However, I find the sound that I get from the on-board speakers is a little too bright for my tastes, at times. I have been adjusting the master equalizer slides but cannot get just exactly what I want. However, I have found that the sound I hear through the earphones is perfect. It makes me think that maybe external speakers would give me the sound I want. Or ... maybe it is possible to hook a set of L/R speakers with a single jack right into place where headphones plug in. Any thoughts on this AND if you agree, do you have any suggestions for external speakers that are good quality.

Don, indeed if the sound is perfect thru your headphones then there is a %99.99 chance that GOOD speakers will give you the exact same sound. For instance I hooked up my Yamaha S 90ES to a Roland HP-207 and the sound was PERFECT. In my case I didn't like the GP sound of the S 90ES at all, so headphones or good speakers it didn't matter (that is why I bought the Roland for its GP sound) but indeed the sound of the 90ES was perfect when connected to the Roland HP-207 built-in speakers. I have also tried the JBL 15 EON (powered speakers): VERY nice; I would recommend them. Just be aware that they are $599 each. The only thing I don't know is whether the result would be the same if connected using a "T" cable to the headphone plug (my HP-207 has separate jacks input / output). Maybe someone else here can answer this part of your question.

Hi Oliver,

Thank you for the response. It sounds very encouraging. I would rather it not be quite so expensive but if it produces the "perfect" sound I am looking for it would be worth it. You mentioned a T-Cable for my headphone jack so that answers my question about hooking it to my headphone jack. I will probably try using the OUTPUT jacks (left/right) before looking into that option.

Oh Don, you do have output jacks! Great!. You know I am sure you have a Guitar Center next to where you live..maybe not too far...? Go and visit them and see if they have the JBL. They certainly have the M-Audio. very good as well BUT I heard / read a lot of issues about the M-Audio... well... just one issue.. for many people after a couple of months one speaker stops working... maybe by now it is fixed? But for the price difference it is worth it? These JBL you will keep them for a very long time (they won't be obsolete soon that is). Ask GC to hook the JBL or M-Audio to a keyboard for you. You'll hear how good they are.

You might try running it through your stereo if you happen to have one handy, that would be a big improvement over the onboard speakers and wouldn't cost anything.

Oliver,

When you say JBL, that is a line of speakers. Do you have any particular model or specific speaker in mind ?

buman was suggesting the JBL 15 EON speakers ($599). Expensive. Fortunately for him, he has lots of money to throw around. smile

But I don't think you need to spend that much on speakers for home use.

Your CP300 has dual 30 watt amplifiers, but I don't know if you can hook speakers directly to its internal amp. If not, you'll have to feed the line output to an external amplifier. You can get a decent stereo amp for under $200.

There are many speaker buys on Craig's List. That's where I found a pair of JBL G400 speakers for only $100. (I posted PICTURES.)

So have a look on Craig's. Ebay has plenty of listings, too. But with speakers, local buying on Craig's is beneficial ... you eliminate the shipping costs.

Well, it is good to hear that it may not be necessary to spend so much on this. Actually, I just found a pair of AIWA, 80W speakers that I have not used in years that I might try hooking up to see how they sound. However, I noticed that the output jacks on my keyboard contain 3-prongs and the wires coming from my AIWA speakers have only 2 different wires, so I am not sure how that would be resolved. I hope someone at Radio Shack will know that.

Are you sure those are speaker connections?
They're probably XLR line outputs. You'll need the proper connectors ... and an amplifier.

Sorry to say that you cannot possibly throw money into QUALITY. You throw money away when you buy cheap stuff... And if I had LOTS of money I would be enjoying E. John's Red Piano smile

Anyway...

Don, the M-Audio or the JBL are a) Powered speakers (no need for amplifier... b) They have both jack and XLR inputs

I think you can insert a picture on this forum. If you can take a picture we may be able to help you further.

Oliver

You are right. I checked more closely in the manual. However, I do have L/R output jacks labeled MONO. When I connect my headphones into each of those I get sound but at a much lower volume and only one speaker in my headphones is delivering the sound. The manual says I should use POWERED SPEAKERS. Any suggestions for quality powered speakers ?

The CP300 does not have speaker outputs. You have to use the line outs to an amp (separate or powered monitors). Of course, if your really wanted to you could open up the enclosure and connect to the internal amp, but I wouldn't recommend it smile

The JBL EON 15 are more (powered) PA speakers than monitors right? I think it is a bit overkill (15" woofer and 300W is quite a bit). There are many powered monitors out there for 200-300 that would a big improvement over the built in speakers. I've have considered it myself many times, but I think I'd miss the feel of the vibrations in the keys. Somehow it adds a dimension of realism to the piano.

Perhaps. But don't tell us we should pay top dollar, either. Not all of us can afford to overpay for equipment.

Well, I just purchased 2 KRKVXT4 powered monitors from ZZOUNDS. They were very helpful and sounded like they knew what they were talking about. I hope I did the right thing.

I'm guessing you need sound equipment for use in the home (or other small locale)?

If so, these KRK monitors should nicely fit your needs. (The JBL EON's, suggested elsewhere, are way too much for home use.)

The KRK's are not floor-standing speakers, nor bookshelf speakers. So you'll want to place them on stands of some sort. The speakers should be at ear level, fairly close to the piano. (Studio monitors are not meant to fill a room with sound ... they're meant to be "aimed right at you, seated nearby".)

dmd, I think you will be quite pleased. KRK is a very good brand and the VXT4 are well regarded in the studio space. Maybe a bit on the small side though, but remember that if you think they sound good but lack deep bass, you can always add a sub later.

Please let us know how they turn out!

P.S. They are quite small, I would try placing them on the CP-300, right where the built-in speakers are, but toed in and angled up a bit so they face you.

Wow ... Got the Speakers today !!! Pretty fast service.

That is the good news. The bad news is that they presented no appreciable difference over the built-in speakers on the keyboard. So, back they go.

However, through this process I have discovered that I am able to modify various parameters to reduce the brightness of the sound in ways I hadn't previously known about. I think I will be able to modify the piano tone to a point where it is fine.

So, for now ... no speakers needed.

Yeah, that's not really too much of a surprise to be honest. 'Cause the CP-300 is said to have one of the best speaker systems of any digital piano. So I didn't really think external speakers would be the answer (sorry I didn't share my opinion earlier...). But as you are now finding, the CP is a very deep instrument. So if your only problem is that the sound is too bright, and you don't have any problems with the samples themselves, then there should definitely be a way to darken up the sound a bit. If a regular EQ is not getting it done, try a parametric EQ. Or, better yet, look for the settings for the "low pass filter." As the name implies, it lets the low frequencies through and cuts the higher frequencies. You should be able to adjust the cutoff frequency which is where the rolloff begins. So if you lower the cutoff frequency, more of the high frequencies are lowered and the tone is darkened. This may well work better than an EQ for your problem. I've never played or saw a CP300, so I can't really mention specific settings or parameters, though. Lastly, see if the CP has some sort of brilliance control that you can turn down to bring the overall brightness down. In fact, it may even have a "lid" control like some of the Roland products, allowing you to "lower the lid" to darken and mellow out the sound.

Good Luck!

Well, here are some of the parameters available to me. If you (or anyone) cares to comment on something that they may know something about I would appreciate it.

BRIGHTNESS - This would be the most direct means of dealing with it but it does not, in itself deal with the issue.

EQ LOW FREQUENCY - For adjusting the low-range frequency of the part EQ

EQ LOW GAIN - For adjusting the low-range gain (amount of boost/cut of the low frequencies) of the part EQ

EQ HIGH FREQUENCY

EQ HIGH GAIN

TOUCH SENSITIVITY - This also tends to affect the brightness of the tone.


I have had some success with this and the sound is pretty good now. However, I would like to reduce the BLAM effect when I hit a key fairly hard. I sounds very metallic.

Any help is appreciated.
