Yamaha KS-SW100 Subwoofer

[3dc]

Hello everybody!

I wonder if anybody here is using Yamaha KS-SW100 keyboard subwoofer with SX600/700/900? There are literally no review videos on YouTube so I am wondering if its worth the price and how much can this subwoofer improve the sound from Yamaha SX keyboard speakers?

Would you say this setup would be also good for sound monitoring in music production or should I go for dedicated studio monitors? 

Thanks for help.

[Normanfernandez]

I can't say much about the Sub woofer.( As I haven't used it)

But using the keyboard and a sub doesn't end up being a Monitor Speaker. 

It could be better or just as same as a 2.1 Setup.


You'll require monitor speakers if you want to get into the studio line.

Reasons being
1. They are facing your ears.
2. Flat response for the most case.
3. Having the speak Subs directed to the ears will give you accurate listen.
On the other hand the sub Is good for listening.
Also can reference how it sounds on the sub.
Common technic used by Music Productions.
To test the track on Different speakers and location.

This is based on my opinion.
Hope it helps you.
Regards Norman.

Thanks for feedback Norman.

Its fascinating that no one in this community is using this subwoofer. 

[Normanfernandez]

If you're a Tyros or genos user you'll probably not need an extra sub.

For the mid range some of us are broke ( like me )
We can't include a sub 

If there's a return policy.
Just test it out and see if it fits your needs.

I own a KS-SW100.
I've used it coupled with the PSR-S975 until last year and now with the SX900.

The magnitude of the sound you can hear is really huge....nevertheless I agree it can be a matter of personal taste.

Hi;

I have recently changed my keyboard from a very old Tyros to the SX900 and as the Tyros had a sub woofer I automatically purchased one for this keyboard.

I have to say the sound is AMAZING and would definitely recommend it to anyone.

Hope that helps.

Hi 3dc.   I also have just bought an SX900 and also bought the subwoofer as well.  There is a big difference when connected to the KS-SW100, overall sounds better & far richer than without. As always down to personal taste but would not be without mine.
The SX900 also has a setting in the EQ section for when you are using a Subwoofer. It is a recommend from me

Thanks for feedback guys! For a moment I was worried this subwoofer was some sort of a Yamaha mistake.

@Norman: I am going to mix my music trough studio headphones anyway. I just hate to buy tons of expensive gear I would rarely use. The SX keyboard with subwoofer would be an ideal setup for me since these keyboards have their own audio interface build in and they seems to be good enough as midi controller for FL Studio. Just like you I am all about minimalism ( severe budget control ) in music production.

Sounds good!
I was going to recommend Headphones but I didn't know if that was going way off topic.

Headphones would also reduce the studio setup cost. 

Glad that you have come to a conclusion.

Ive got it on my s775 and the sx900 it makes a huge difference my only dissapoinment is the power button is on the back other than that its a powerful and clear subwoofer for its size

[Normanfernandez]

100 W RMS is no joke.

[Enildo]

With all this talk I think I'm going to buy mine. 
I've done events where I used only the built-in speakers on the keyboard, but I always thought there was a little lack of strength in the sound.
I think with YKS I will have what I want, the minimum equipment, light weight to carry and a good sound to perform at certain shows!

Enildo, for gigs you need a PA system, like the Bose L1 compact line array system.

[Graham UK]

Sub-Bass-Units...To get it to perform at its best. My experience !
To get a low clean Bass Sound without upper bass boom.
Setting Up...Listening to BASS UNIT only with no additional speakers.
We are wanting low clean frequency's.
Raise a few inches off the floor. Trial and error.
Keep away from room walls and corners.  Move a few inches each time and test.
Sound also changes with the position you sit in relationship to the Sub-Bass.

Hi 3dc,

please note: Only the (relatively) new SX600 has a built-in USB AUDIO interface. SX900/700, Genos and also all previous Tyros or PSR-S models do NOT have a USB AUDIO Interface.


Best regards,
Chris

[EileenL]

That is because these keyboards have Hard Drives fitted so no need to record to USB.

Hi Eileen,

I think you have misunderstood me:

With "built-in USB AUDIO Interface" is meant the possibility of establishing an digital AUDIO IN / OUT connection to a computer (for recording purposes with a DAW like Cubase) via the USB-to-Host connection (instead of using an additional, external Audio Interface).


Best regards,
Chris

Huh! Thanks for info. Baffling if you consider that older and much simpler E463 does have an audio interface. 

By the way I am reading the SX600 manual and it says it can be set in Midi Controller mode. Does that mean the two rotating buttons can be reassigned in DAW? Can anybody confirm this? 

[Tyros1]

As i can see my SX 700 dosent have sub out?
Only SX 900 have this.
Its it possible to connect a sub to SX 700 then?

Hi Tyros1,

the "SUB / AUX OUT" sockets of the SX900 are not used to connect an external Subwoofer. You can use these sockets e.g. to output the bass and the bass drum separately (e.g. for live or studio applications in connection with an external mixer). Or you can use these sockets as an additional Stereo Output that outputs the same signal as the MAIN Outputs.

Important: The signal at the "SUB / AUX OUT" sockets is always output at a fixed volume. So it is NOT influenced by the Master Volume controller.

An external, active Mono Subwoofer, such as the Yamaha KS-SW100, is simply connected to the left MAIN OUT socket (L / L + R). As long as no plug is connected to the MAIN OUT R, a MONO signal is output at the left socket. And of course the whole thing also works e.g. on the SX700.

Then set the desired volume of the sub-bass frequencies on the Subwoofer (once). You then only control the overall volume via the Master Volume of the keyboard.


Best regards,
Chris

Hello Toril!

Yes, I already have a sound system with two boxes that have about 300w RMS each, for my Gigs.
But depending on the location, such as apartments, home rooms, small meetings, etc., only the SX900 speakers are needed.
I just need a little reinforcement and I think the Yamaha KS will give me the little bit I need.
When buying a pair of Bose L1, it would be a dream for me, but it is far from my budget or what I intend to spend to have a better sound system.
My goal today is to replace my speakers with the JBL Eon One, which has the same system as the Boses L1 and at half the price and a sound quality (bass, treble, SPL, etc.) highly praised.

Hug Toril!

Enildo, yes, the Bose speakers are rather expensive!!!

[Totomo]

The KSSW100 is only 50watts sub.

How about give a look on Edifier S350db 2.1 system .

My Sx900 pair with Edifier S1000 mk ll, lot of low end in my practice room and no harsh tone issue at near field listening  .  But, the S2000 mk lll has more output , more low end and better hI-end for wide field listening.

The Yamaha KS-SW100 is only suitable to extend the bass fundament of the internal keyboard speakers. I prefer to use a Fostex Submini 2 with my SX600. The Fostex woofer has a stereo input and output. So I could use it with external speakers too (what I don't need at the moment).

Hello everybody

My KS SW100 arrived this week. It really makes a big difference.
For some events in apartments and places where people don't want a lot of noise, I will just use the keyboard and it.
I didn't like the configuration for Subwoofer that comes in the preset, so I made my own configuration.

I try all KS-SW100 ,NS-SW050 and NS-SW100 , end up with 10in driver NS-SW100.

Actually both KSSW100 and NSSW050 has no different, they has same 8 in driver, same working frequency range ,same size and weight. But weird the KS price are in between NS050 and NS100.
Only KSSW100  has 6.3mmjack/ RCA cable include in the box.

I dint found much sound different between NSSW100 with both KSSW100 and NSSW050 , but NSSW100 has more juicy low end while use the style like Dance and DJ .

[Totomo]

My EQ tweak for SX900 onboard speaker with NS-SW100.

I tweak 2 set of EQ , one are modified from GENOS EQ-GOLD.  The modified EQ-GOLD sound more HiFi-ist , meanwhile the another one sound more full body to my ear.

I also create a compressor setting to thicken up  " Upper Lo-MID and Lower MID " tone a bit . 

Sub woofer level knob are set around 5 -6 possition for my taste.

So far, i able get loud clean and clear sound from the SX900 while volume around 3 - 4 o'clock without fart/distort problem on Onboard Speaker.  Except 1 of the Elec Piano sound from Legacy bank get rattling when playing on LOW NOTE with sustain engage .  I recommend volume around 1 - 2 o'clock for comfort listering without damage hearing.

Another issue i meet is factory Concert Piano sound get lost while mix with some heavy/aggressive style . Will try to tweak the piano sound soon.

Hope you guys who own SX900 + SW100 enjoy with my EQ setting.

I dont know why cant upload the attachment.

I received my Yamaha KS-SW100 Subwoofer yesterday for my SX900. I took the subwoofer out of the box, plugged it into the wall socket, ran the cable from the subwoofer to my Main Output (L/L+R) jack on the back of the keyboard, turned the subwoofer on, and started to play. I was absolutely blown away by the sound richness it immediately added. I will probably make some EQ adjustments in the days ahead, but straight out of the box, plug-and-play, I was very impressed. This was for a home set-up, and I realize musical tastes vary quite a bit, but I, for one, was pleasantly surprised with what this subwoofer added to the already great sound produced by the internal speakers of the SX900.

[Totomo]

After couple weeks on EQ tweak, i found that my previous EQ setting (especially the Genos EQ) still sound little harsh and lacking something on 300hz ~ 500hz frequency range from SX900 onboard speaker, but no problem with external speaker . 

Here is my finetune EQ for SX900 onboard speaker matching SW100.
