I have this Yamaha sub YST-SW315. Is a 10" but i felt that not solid as i wanted !!

How can i set it more Solid !?? i want a solid bass. Clean and Clear !

I using YAMAHA RX-V467 AMP.

I go to MENU->SPEAKER SETUP->CONFIG->SWFR (i actually MAX the sub vol in my AMP).

I select Music setting. The sound is very clear for vocal. Is just the BASS is not SOLID enough.

I using normal RCA cable.

I had this sub last time, there's nothing wrong with the settings, the sub is a bit too polite and driven hard will cause it to distort and vibrate. If you want a better sub, go for Velodyne CHT series.

izzit Velodyne CHT-10 ? approximately how much ?

For the Yamaha YST-SW315 i need to turn it nearly max only have the "punching" bass sound i need. Haizz...

Some more, from 0-140KHZ for me like no different

Put the Sub in the corner of the room

Ok, so your sub lacks the "solid" sound you want. First you have to determine if it could be the sub itself (i.e. not high performance enough) or your placement.

A sub is not "plug and play". To get the best out of a sub you have to experiment with placement. Please check out some of the articles on sub placement/positioning on the net. Then experiment with moving your sub around. Like azbro suggested try putting the sub in a corner (this helps to boost output).

If after some experimentation your sub still not giving you what you need, then perhaps it's time to upgrade to a better sub.

ic.. for Movie this kind of Sub sound is ok.

For music i really hope that the bass sound like BMB speaker XD. Solid and heart beating enough.

I believe that your source of audio / music also affects your audio / music quality.

Hi Azxel those sources u meant is Cable ?

I found out down firing is not really that powerful too.

I think azxel meant is whether you are playing music from bluray, CD, mp3, flac, etc. As you know some are lossless, some are lossy.

Personally, while there is some difference I think those differences are minor (or maybe I don't have golden ears like others ).

As for down firing sub, there are many threads about this on other forums:

Thxs for the info.
Do u guys have any ideal how much is Velodyne CHT sub ?

And where can i sell my Subwoofer that just bought 2weeks ago = =

I think the Velo CHT-10Q is about 2.3k.

There's actually an old thread about it: http://forum.lowyat.net/topic/1257653

Anyway, before you purchase always go and audition first.

How come i got this kind of hobby man !!

Will cost me alot.. since i dam like audio stuff

Within 1.4K, you can own velodyne subwoofer.

Sell to us and grab the velo sub.

Wah, got trade in offer some more from CT Seong.

cht or impact?

CHT 10"inches

entry series - Impact

cool. go for it. uncle had one last time. very good sub. great impact. too bad has to sell coz uncle's heart can't take so much beating

remember to read the manual

Yea.. I kinda meant that but more of... if you're listening to MP3, what kind of quality is it at?
I noticed my mp3s also have different sound quality... something to do with the 'kb'?

Now back to topic.


1st.Did you set the Front, Center, surround speakers to "small' or "Large" on the AVR.
If you set the speakers to "Large' but using small speakers, there will be no bass coming out of the Subwoofer.
If you set to "Small" for Small speakers, the bass freq will be directed to the Subs giving you better bass.


2nd.I also did encounter loss of bass between sources. Only to find out that between sources, the settings is also different.
Depends on the AVR, you will need to set the settings again...if not they will be on default settings.
Example, if you have set the best setting for the DVD source, the same setting might not follow for TV,VCR or multiple input source.

I think i set my surrouns speaker to Large as i following the default setting lo.

Later back home will try to change the setting.
Thinking of selling YST-SW315.

= = only 1week plus = =

That could be the reason

Never set the Front, Center and surrounds to 'Large', unless you are using a very expensive and powderful AVR and massive floorstander speakers with 10~12 inch speakers built in!

Set all to "Small". By doing so, the low freq will be diverted to the Yammy Sub.
You will even get better sound from the surround speakers and also lessen the AVR load to play all those bass sound.

Try it out

And remember, If you use multiple sources....check between the sources that the setting remains the same.
Example media player and Bluray player Large/Small, Tone etc settings. On some AVR models, you need to set again.

Note: YST-SW315 should be adequate for most ppl except for those bass head sifus replying in here. Dun get poisoned by them You should be fortunate to own a Yammy Sub, other ppl like me only cap ayam Sub, before that, I was DIY Subs with old components and cheapo jalan pasar speakers..hehe

icic.. Only set the speaker to Small right ? then others just remain the same ?

I just know how to judge is the sound for Music is good or bad.

In term of Movie i still not good in it. Thats y i request for "solid" bass.

1 More question. If i use my Laptop to play music.
What sort of cable should i use ? izzit the banana head ?
(output from LAPTOP into my AVR input infront of the AMP)

or shall i use RCA cable to input my AMP and Buy a converter for RCA into banana head.

Set all the speakers to "Small"....Front, Center and Surround (back)

Laptop? well, most of the time you will get only stereo from a lappy...but can you be more specific what model / brand is your lappy. Wanna check the specs.

I guess if you want to use it for music only then its OK for stereo.

Thks azbro u been so helpful since the 1st time i came here.

The output for my Laptop is just normal hole. Yeap i think is Stereo.
Dell Studio 15 i guess.

Hey, a word of 'thanks' goes very far

If I'm not mistaken, the Dell Studio 15 comes with HDMI port and the means of getting a 5.1 audio out of there.

Your Yammy AVR also has HDMI inputs..

If you dun have a HDMI cable lying around, just go to Tesco and get the RM19.90 cable to test it out.

IC wow..nice nice. so HDMI cable that sell is everywhere is the same?

I mean is all standard ? can use for PC/LCD/TV/AVR....bla bla ?

Basically, you can categories HDMI cables to free, cheap, expensive. and then there is the standard 1.2, 1.3, 1.4..1.3 itself got a few variant...

But no need to confuse yourself...go to tesco and grab one

Here is how it looks like. Pictures from a member named PrincCaspian:



And remember this, I can't guarantee you it will work, depends on you Lappy and the software.
but at RM19.90, its worth trying it out..but if you connect it to AVR, you need another cable it from AVR to LCD....but I'm sure you can think of that. How is your system like now?...what components are you using?...example LCD, Bluray player, AVR, PS3 etc. You must make sure all are properly connected...if not another trip to tesco will you will be tired

And when you go to tesco, go alone, never bring your wife and kids cause the RM19.90 cable will cost Rm200 out of your wallet because of the rest of the junk food etc

lol azBRO u must have gone through this ! i'm still in a relationship status XDXD.

I just have my LAPTOP and 1 cakai DVD player with RCA cable only.

Have been working for 4months only. still not afford to high end product like bluray bro ~

Take small steps bro..and best is to ask question before buying anything...you wouldn't want your hard earned money go to waste for buying the wrong stuff.

yeap. May i know how long u have been playing AV system ?

Oh, everybody thought you're offering that price for CHT-10Q.

Just to clarify...

In a movie soundtrack bass info can be found in 2 places: (a) the normal speakers channel (front, center, surrounds) and (b) the LFE channel (for the sub).

Info in the LFE channel will always go to the sub. So even if you set the speakers to L the sub will still play the bass coming from the LFE channel.

Once you set the speakers to S (and if you can select the crossover freq) then that means the bass info from those speakers will be redirected to the sub. Meaning the sub will now play the bass from the LFE channel + bass from the other speakers. So for example if you set speakers to S and crossover to 80Hz, then any signal in the front speakers which is 80Hz and above will be played by the speaker, below that will be played by the sub (remember the sub will still play all the signals in the LFE channel).

wow.. what a deep explanation ! is time to learn how to play with the Hz / Om / dB..

if not really scare my speaker and AVR will busted !

Anyway thank you so much for the advise.

Much appreciate

Yeah...try it out tonite...I simply cannot believe your system lacks bass!

what abour crossover? 160hz ok?

This post has been edited by azxel: Nov 18 2010, 10:29 PM

i just set my crossover to 80Hz.

May i know how is the crossover works ? izzit related to our speaker ?

Crossover depends on your Surround speakers....if they are smallish, you can set it at 160Hz for the sub to take over from there.
If they are surround speakers are capable of more bass, you can set the crossover to 80hz.

So bro...oledi set them to "small" or not? How is the bass now?

yup set to small d and place it at the very corner. Not really try out yet coz is at night. I don't really dare to open that loud. Maybe later after finish work 3something i try and let u know.

Bro, my Yamaha amp right. Got few setting for front speaker and surround speaker. So can teach me how to set all of these speaker KHZ ? or crossover? Thanks

First, I need to know what brand model are your Fronts, Surrounds and center speaker...

Bro, my set is here (with pictures) :
http://forum.lowyat.net/topic/1642611

This assumes the sub is capable of reproducing freq up to 160Hz. Some can, some can't. Like the CHT-12Q and 10Q their limit is up to 120Hz only.

Wah, you're selling off the whole set? Thought you just wanted to sell the sub.

ohh..really huh...then it will create a void during those frequencies


Try 80hz first.....then you have to play around with the settings..I can't really tell you specific what to set because this is not just text book thing. Need to be there to adjust the sound depending on your liking, surroundings, etc.

Try play around with the phase of the Sub...but usually the default should be OK.

Bro there is a setting behind the sub which is Normal/Reverse switch.

So which 1 should i choose ?

I think thats the Phase switch...set it to normal.

So how?...still no bass?

Bro i listen to u : Put in the most corner / switch it to small speaker

Still not satisfied i don't know what else can do

Wondering izzit my darn ear problem. Even i sit beside my sub still felt lag or solid sound.

I don't know how to explain the bass quality. Like a band: the Bassist voice is louder. Then when reach the drummer bass i very low

i really dunno what to say bro....most sub box...even cap ayam ones got the capability to make the neighbors knock on the wall.

Did you up the volume or not on BOTH AVR and the Sub own volume knob?


this could be a setting issue..

This post has been edited by azbro: Nov 20 2010, 02:48 PM

I max the SWFR in my AMP

The sub it self i set to 3/4 full. If i nearby the sub is quite strong. If i walk far away still like that nia lol..

Should go and test the Velodyne. Maybe psycho by Velodyne seem so many ppl said it is Good Sub .

Then try to Reverse the phase...

By the way,,,how far is it from your seating position to your Sub..just estimate will do.

what do u mean by reverse the phase ? what is phase?

erm.. i sit maybe 2meter from my system?

Heh heh

Candidate for HTlegs poison liao..

HTlegs poison?

See the phase thing at the right...is it in normal?....If normal than try Reverse it...is the bass getting better?

Lol bro both i tried same effect .. lol .. Yamaha sub got so cacat 1 meh?

u need a proper adjustment instead of changing the whole set.

Please run the YPAO room calibration. Set the volume knob at the sub to mid position when you do this.
Take some time and read the manual on how to do this correctly.
After this calibration set the speakers to small and the cross-over to 80Hz or 100Hz for the sub.
You may also be sitting in a null position. Try the sub crawl to find the best position.
Set the phase to normal during the initial set up.

Setting the gain to max for the sub at the avr will give a lot of distortion and no head room.
Try and achieve 0dB or -2dB for the sub after calibration. This will mean adjusting the volume level at the sub and re running YPAO calibrtion until you get the desired level.

This may all sound confusing and steep learning curve but once you have done it, it is rather simple.

Thankyou so much for advising everyone. But this is so complicated man. Those setup izzit in Setup --> Speaker Config. Everything inside ?

You should at least read the manual book once to know what functions and setting it has. Then refer back when you encounter a problem.
99% of info are in the manual book.
Stuff like these are never 'Plug ad Play'.
And its really a waste of money just to sell it off just because you dunno how to set it.

Some ppl like me only dream to have a system like yours

I know. But the manual comes with a CD. Is not a book. Plus my Pc monitor died. Thats y. lolz.

Azbro u wake up so early ho everyday !XD

Added on November 22, 2010, 8:20 amBro the set is very normal set only. I believe that u will a better set than mine XD

umm... your PC monitor died so you can't read the PDF file but you can still surf and post stuff on Lowyat.net?

Anyway... I'm still curious as to what your reference audio files are.. Playing from CD? MP3? Watching DVDs?

lol bro. I using my office pc. thats y cant bring any cd or usb lolz

even picture that u guys attached i also cant view.

Now my plan is:

Since i still have no budget to buy new plasma TV

So i decide to buy a LCD monitor bout 22 - 24 inches.
Then, output HDMI from my PC to LCD monitor to play DVDs or MP3. I dont really use DVD player to watch movie. Coz my DVD player very cakai one = =

Oh... I see...

Umm... HDMI from a PC to a 24" LCD Monitor for MP3? How about your Yamaha set?

Bro just went to lawyat to grab the new Samsung LCD BX2231 with HDMI. But still confuse for the setting lolz..

I try to OUTPUT the HDMI from my PC into the YAMAHA AMP. After that i OUTPUT from AMP to LCD. Will it works ?

Of course it will work lah...provided your setting is correct...

I think you should need to read the manual book before asking such a basic question like that.

If you can't access the book at home, then get it printer out somewhere.

Bro do u good in PC stuff too?
