Problem with Sub placement...
The problem with powerful subs is you can put them under a desk.... or in a corner, especially not under a desk in a corner, as the 60, 70 and 100hz areas of sound get amplified way out of preportion and ruin the sound.
So the obvious point would be to move the sub out of the corner, right?
Not quite that easy.
I have tried placing it against the wall to the left of my desk. The sound is great, sounds as it should and no booming.... except I can tell that the sub is to my right next to the desk....
The sub is now where the Amiga was (white case, single black bezel machine) and the pedestal directly next to it has gone. So it's not where it is in the picture.
Any ideas?

beauty of a sub is that technically placement is not all that important but really should be at ground level preferebaly with carpeting.

move it someplace out in the open like a "coffeetable" type of deal. what does your floorplan look like in the rest of the room?
What I have now done is turned the sub so the port is facing into the room (in the pic its facing the side of the desk) and bought it out a bit, but it has only made a marginal difference....

(Excuse the picture, if I turn the flash on then everything is too dark to see properly).
try it in the middle of the room first and work from there perhaps.
Sorry, that sentence just makes no sence at all to be honest.

hmm, have you tried to the left of that shelf? where the blue thingy is?
btw nice desk and nice headphones
just don't enclose it between objects is all I can suggest without being in the room I guess. subs mainly move air and it should be placed in a open space.
I've always found the best way to eliminate the problem of being able to detect where the bass is coming from is to leave the sub right at your feet, either directly infront of you or just slightly to the left or right.
Move it away too far and you can start to hear/feel the direction of the bass.
580's actually
I can't put it under me as the bass levels are just stupidly enhanced and it causes 3 spikes (60, 70 and 100 as I said) so that isn't possible. It was great when it was there as the sound was in the right place, but WAAAAAY too boomy and disproportionate.
That blue thing (aka a "Bin") may be too far away. Though which blue thing do you mean? The one directly to the left of the desk doesn't work, I can tell where the sound is coming from, as I already tried that.
Not quite sure what you mean, but the speakers in the picture, going from left to right are - Left Rear, Left Side, Left Front, Centre, Right, Right Side, Sub (on the floor) and the Right rear speaker is just off the picture to the right.

look familiar? 580's rock
too bad that keyboard broke.
ok back on subject .... I had a 4.1 system awhile back (altec lansing 641, nice system and i got it for $100) and i placed my sub behind me against the opposite wall .... if you have enough cabling ... can you put it on the opposite side of the room?
better. do you have an amp? you will wet yourself.
Thank you.
P.S. if you use a high power home theatre amp like that, TURN THE VOLUME ON EVERYTHING TO ZERO BEFORE YOU TURN ANYTHING ON, THEN ADJUST IT. You will thank me.
I don't have enough cabling due to Creative using "Photo to Dual Wires" method, meaning I would either have to buy loads of extended wires, as the rears have enough of a hard time reaching as is.

The sub is the 210W RMS Creative Gigaworks S750 Sub -

So where do you place it?
I think the more "walls" you place it against the least happy you'll be with that "directional" effect IMO. That is why I suggested starting in the middle of the room ...get the decibals comfortable for you (and heaven help those downstairs) then move it to a corner at most. The fewer walls you have directly surrounding the sub the happier you'll be IMHO The reason you feel the direction is because of the sound/air bouncing off of the objects directly nearby ...make sense?
My guess is ...210w sub and you are no longer popular in the house AND someone is considering a basement quarters for you!!! j/k
At a guess, since your setup has most of its speakers left of the computer, your ears are also hearing its sound to right, making things worse, but I would not be surprised if part of the spiking is RFI\EMI interactions between electronic things. SUBS can have a big field, and if not real well cased can be interfered with also by things like monitor EMI\RFI. So, I would get some cable extenders, put it behind you, bounce it off ceiling from behind as a trial, see if you can get the reflected sound to sound decent or if not then move computer to where bookcase is, and put a shelf on wall for sub (thick dense wood, protects from RMI\EFI interference by basicly not allowing it through if it is not soft and sappy or green wood), or make a grounded metal plate UNDER it to divert RFI\EMI interference from below to ground instead of up into sub.
Only other issue I can SEE, is if ceiling is hard plaster which has been impressed\stamped\carved, or metal, is that ceiling sound reflections will make things awkward. Looks like you are trying to eliminate that with your setup, but moving computer against wall and using foam if needed on part of ceiling that reflects sound worst would look tacky but eliminate sound bounce. Even fabric covering on foam mounted to thin plywood would dampen some.

Of course staying a way from windows if possible...
They suggested trying to turn the sub in different directions. Examples were fireing it right into the wall or turning it so that the sub fires into the floor...
It looks like your on an upper level so I suppose that firing into the floor woouldn't please the peeps below you...
I found that my pc sub sounded the best turing it so that it fire into the wall but in the HT I set my sub in a corner almost behind the listening position... that is where the corner post to my foundation is so I think that is why it sounds good there.
It helps to have a suspended floor too that is made of wood...
Concrete absorbs too much of the vibrations and you lose a lot of boom...
Is it just that the sub is in the way or does it not sound right? You could try getting an analog sound meter and trying to set your sub settings to blend to the same db as the rest of your system...
I did that on my HT, made a huge difference, I had always had trouble with getting my base just right, but after setting everything via a sound meter I can't tell where the base is comng from and it sounds great... I used a cheep $35 USD radio shack analog sound meter to do it.. was really simple to do too...
gl,
"g"
I have already replied to this thread once, where did it go....?
Anyway, basically I tried putting it near the monitor, but I couldn't put it within 2 feet of it otherwise it went crazy, plus it sounded crap, but I have now put it... cant explain, i'll get a photo....
