never heard m50w before.. heavyarm say the clarity will not on par with x3, then i don bother to listen edi haha..

sp2500 is smaller to begin with. size does matter
anyway, nice setup u got
want more rumbling bass? place it at room corner and adjust sub volume accordingly
port point to the wall facing u, distance close up about 5"

unlike home theater receiver or amp, PC cannot do the bass crossover job.
so, pc (line level) >h6 (high pass) >h4

i suggest sp2500 put corner because it is ported sub, need wall reflection to gain deep bass.
h10 is seal sub. no port
u can try 1 "back wall" reflection instead of 2 wall (such as corner)
should give u cleaner bass line & less annoy outside ur room. haha

Vented/ported subs have holes in them to let air escape so you can make use of positioning to so call "boost" your bass.

well, if u dont reflect the port, u cant get enough low & deep note from single 8" sub
i saw ur table pic, very tidy. if u already satisfy, leave it as is
if like experiment, u may try this..
under table, sub face right. stick close to wall

ok i tried tilt it down, now i feel some better bass lolz... maybe tilt too high..

couldnt wait any longer already

For now, it sounds great, but not awesome yet, have been running for 4 hours only. But Cyntrixtech what about those settings behind the H4s? For HF anf MF I know adding a sub shouldnt affect those, but what about LF and the HP?

Since Im using a H10 now, does the LF part doesnt matter anymore since the low frequency is being handled by the sub?

the HP is at 72Hz now, meaning that the satellite  will handle until 72Hz only right before passing on to the sub? the sub is at 80Hz now since "direct" will sort of turn off the sub. So wouldnt there be a conflict between the sub and H4 when playing sound between 72 and 80 Hz?

Im really blur now lol, so maybe all the sifus here can give some enlightenment

maybe keyoke can also share his experience?

-1 eh? will try and see whether it helps in clarity or not. Yeah i thought this will have a nice crossover adjuster at least if wanna try out audio without sub is easy, just change to direct

actually, I'm using K58, sharp eyes you have really nice case which haven't gave me any reason to change
and man, that is HUGE!! does it play well with the H4? not bad, have a dad who is interested on this stuff also

Hopefully they have something internally to make the H series sub and speaker to blend well so that clash between 72hz and 80hz isn't too bad

Wow, bigger sound stage by changing subs? Maybe you might need some bass traps to make the H10 less boomy? Btw, what are your system, speaker and master volume on the sub like? I think I'm only at 12.5 % now after taking into account all three volumes lol, guess my room is very small for this speakers

But seriously, the placement of the sub makes a HUGE difference in my case. Just a little distance difference meant getting either super boomy bass which makes you nauseated, or really nice, smooth, and actually sounds different while playing difference songs

It's pretty amazing really how sound travels across the room and how a little bit of placement tweaking can make a whole lot of difference.  Oh yes, may I ask what is that below the H4s that you are using to bring the speakers to ear level?

Need to find something to raise the speakers

Lol, exactly the same volume settings, just maybe my sub volume is slightly lower.

At that position in the pic before, standing right in front of the sub gave me boomy bass, standing while facing o the right side of the sub makes it completely boomy. Sitting on my chair gave zero bass,as if I don't have a sub lol  and after moving the sub to the opposite direction about 1m,and bam! Everything works just like it should.

Need to try some songs with lots of cymbals and other high frequency to see whether the HF level is good or not.

subwoofer langgar phase with main speaker.
either u turn the "0-180 phase" knob at subwoofer
or terbalik the red and black wire

0-180 phase work this way:

0 phase
u play a low note.
main speaker cone push, subwoofer cone also push.
becos of wall reflection, subwoofer push sound will be bounce back inverted become pull.
push + pull sound will cancel off each other = bass dissapear, u lose detail



---------------------------------------------------
180 phase
u play a low note.
main speaker cone push, subwoofer cone pull.
becos of wall reflection, subwoofer pull sound will be inverted become push.
push + push sound will overlap, boost the sound level = more bass, but no detail loss.

if this happen, adjust crossover to lower hz or turn down sub volume to prevent over boom.
the sympton above can happen vice-versa, so test ur own 0-180 phase

[attachmentid=3421497]

have you tried putting the sub under your table? on your right? but my table is not all the way to the back, touching the wall, maybe thats why my bass isn't really boomy now? but this is a sealed sub, so isn't corner not suppose to make any difference?

I might need to find a way to reduce that "extra bass" sound from going to other rooms though

sometimes when the speaker is playing loud, if I go downstairs, the bass note is pretty annoying lol.

Yup, moving it just a meter to my left made the bass completely disappear at the place I sit. But where it is now it's just awesome
Will need to read up more on this two stuff. Will really need it to reduce complaints from others in my house
Didn't play much with the phase switch as it didn't feel like it was making any difference will need to try again as I only played with it when the sub was at the non optimum position.

Maybe they only start making a significant difference after burn in? Anyway, glad its not boomy for you anymore

Yesterday i left the system turned on with nothing playing and no fan/AC. when i came back, the sub felt like it can be used for BBQ ready

But i think should be ok la, coz for example those tube amplifiers some ppl use for their stereo system, only once its heated up it sounds good, according to them, so even if these are not using the same thing, the heat should be fine, just ppl like us who are used to completely cool speaker sustem need to get used to this kind of systems haha.

Oh yes, that audio/video setting behind the sub also im not sure of the difference. Will need to test out more.

That much difference with just the flick of a switch  
Will test extensively today, but i think i might need to wait till it burns in to feel the difference, will see how it goes, pretty interesting stuff haha.

Yup my previous was class D. Couldn't make it warm even after playing loud for a whole day. But then again this set which has hardly burned in, is eating a 2 year old sp2500 like nobodies business

So can just close one eye about the heat issue

the best way to check ur phase is use test tone software, such as SinGen 1.2 (freeware)

start with 0 phase, low volume. set maximum hz crossover at sub, LF++ at speaker (in order to maximize the effect of overlap)
play a tone about 90-120hz which makes both speaker & sub exercise.
u listen closely to speaker, then switch 180 phase to check any cancelled out tone.

u can also check room mode reverb (usually 60-90hz) to reduce boom2 sound outside of room

in my opinion, sub (seal or port) should be located near 1 wall to get efficiency & great low frequency effects
u dont have to turn volume up causing  it leaks outside room.
recommend 2 adjecent wall (like corner) for little sub below 8" only

some says down firing sub is easiest to get good sound hoping hivi can make 1

yup, i believe 180 not suitable becos u sub facing front which is same direction as H4.
when H4 push, sub pulls back the bass =cancelled out liao

haha, try it during free time

H10 more like hiding in tunnel

ok, have been testing the 0 and 180 phase a lot for music game and videos and it seems to be 180 has a more pronounced bass level compared to 0, but not to the extent of being boomy, so I'll leave it at 180
btw, guys try listening to Illegal Bass by Bass Outlaws....might wanna reduce the volume before starting to play it, confirm your walls, furniture and everything will shake

don't dare to play this with my default  volume lol
