Perhaps the most important component of a PC / desk audio is speaker stands and speaker isolation.
For a speaker to sound correct it has to be positioned, for example you have to get the tweeters in the area of your hearing. The other thing is when you lift a speaker from the desk it changes the bass and how the speaker fills the room.
There is also optimum positioning of the left right speakers from each other. If you widen the gap between two speakers it increases bass, close the distance between the left right speakers it will highlight higher frequencies. You should be positioning speakers so the vocal is central and sounding back behind your monitor. After this you should toe speakers in so the sonics of the overall sound is balanced.
Another thing to discover is the minimum distance a speaker can be from the wall. Generally you want the speakers as far back as possible (i'm assuming your desk is against a wall), however there is tipping point where the sound quality will suddenly drop off, so normally you would place the speakers just ahead of that point.
I'm referring above to under 1 cm adjustments in distances and height, and small 5 degree changes in toe angle. These small changes are all it takes to adjust the sound. This is why you need proper deskstands you can adjust and lock in place.
If you have a sub, that needs placing so it's sonics are working with the main left / right speakers. Again it's positioning of the sub, how far forward / back to the wall. Lifting a sub on a isolation platform again helps tighten sound.
The other thing important is speaker isolation foam as it stops resonance into your desk that will muddy the sound. To help understand resonance place your hand flat on your desk with music playing, if you can feel vibration that is resonance that's reducing your sound quality.
And regardless if you have a £100 setup or a £1000 or more setup the above all applies. This is why a budget system that's setup correct can sound better then a incorrectly setup more expensive setup.
And none of this is expensive, speaker isolation foam can be as little as £10. Adjustable desks speaker stands there £20 upwards. Subwoofer isolation stands are more money, however you can at first use polystyrene foam to lift and isolate a subwoofer. After this it's just your own time to set everything up.
Yes, placement and the room the speakers are in can make a noticeable difference indeed!
My Focals are on stands at either side of my desk. Tweeters roughly ear level (but they have a wide dispersion on frequency charts so the sweet spot is quite wide, similar to KEFs).
Still using my edifier r1600t with an essence STX 2 sound card (hifi setting)
I actually ran those, and have 2 sets in box's i'm thinking of selling.
Those R1600T's were the best speaker OCUK sold for £50. The downside is the cabinets had a bit vibration in them compared to more expensive speakers, also the tweeter on them was a little harsh, Edifier is now moving to soft dome tweeters. Also like most 2.0 speakers they lacked frequencies below around 50Hz and would benefit greatly from a sub, they were pretty flat speakers however, as in they were not particularly coloured. But overall amazing speakers given what they originally sold for, they sound better with the dust covers off them. Btw nice sound card also.
personally I'm not a big fan of heavy bass so quite like these for that reason,
Any recommendations for speaker stands for the edifier speakers?
I have an Edifier R1280T that I just purchased from OCUK a couple of weeks back. They're pretty good for less than 100 notes.
I have these and they sound pretty good once tweaked the bass/treble
Pure flat reproduction doesn't mean things will sound good. Vital for mixing audio but not so good for home use.
I'm all for using an eq to tame the sound to the profile I like. It won't turn a turd into a diamond but if you've got good stuff you can tune the sound to what you like which accounts for the room interactions as well.
The physical dimension of my room creates a null around 180hz so I have to eq that a bit to get the sound I want....if I run 'flat' the sound is less engaging.
