For mastering audio recordings, usually you have to look for studio monitors such as that Edifier Studio 7 (a.k.a Edifier R2700) shown earlier. Looking at your budget, you may want to consider Edifier Studio 8 (a.k.a Edifier R2800) which is a step up (and they are massive speakers as well)...

Those are kinda small, plus they are one way passive speakers (single driver per channel) only. Thus not sure how well they sound, but do not expect great trebles (esepcially) nor nice bass from them (since it uses a single full range driver only). You will need an audio power amplifier as well... 

Then can go for Edifier Studio 7 (a.k.a Edifier R2700) which is a little smaller than Edifier Studio 8 (a.k.a Edifier R2800). Not sure how much space you have on your desk, for comparison that's a 22-inch widescreen LCD monitor (1680x1050 native resolution) in the picture above. Much smaller than that would be Edifier R1600T III (also an active studio monitor). Can check this review here: Gecid.com Ukrainian IT-portal: Edifier R1600TIII 2.0 Speaker System review and testing which can see that the frequency response is totally flat (which is a requirement for studio monitors). But if you are willing to spend, then you can go ahead and get KRK Rokit 5 speakers...

Nopes. To use those Aune X3 speakers, you will need an audio power amplifier such as Aune X2 amplifier. Have to beware that those small speakers are rated at 15W maximum only (thus have to watch that volume dial)...

Aune is too small for full range reproduction. Plus i believe the tuning is not towards flat eq

interface is not amp. Amp use watt rating. Rokit got built in amp

cheap monitor speaker that i know is from m-audio and wharfedale pro

recording /playback interface is control the audio path & convert analog --digital signal.
amp is provide electric power to speaker, make it push away from magnet.

no good because cheap = small monitor. mid & higher note are flat tuned, but still cannot reproduce low frequency range instrument.

Besides R1600T III, there's also R1800T III which is of similar size though may not be available here. If you have the space then go for Edifier Studio 7 (a.k.a Edifier R2700). For your information, that Edifier Studio 7 (a.k.a Edifier R2700) won numerous acclaim as well, for example: Ixbt.com: Acoustic Roundup August 2012 outgunning other speakers of the same class and budget... 

The main purpose of an audio power amplifier is to drive big (passive) speakers. Usually the most power output from a LINE OUT audio output (from computers) is around 0.1W which may be enough to drive a tiny speaker or headphones/headset, but certainly not enough to drive big speakers. Those small Aune X3 speakers will require more than 0.1W to produce anything useful (audibly)...

Single full range driver weakness has always been the high frequency reproduction (trebles are weak and/or often simply missing). Furthermore it does not seem to have other tricks such as phase plug or whizzer (a.k.a "double cone") for improved high frequency reproduction. Add to the small size of the full range driver and the size of the speaker enclosure, bass will be weak also (difficulty in reproducing low frequencies)...

weak sound or nothing happen at all, becos unable to move speaker cone away from magnet.

buy USB type A to B cable (same as printer cable)
u need custom made audio cable.

pre-sonus, use 2pcs of mono phono jack plug into MAIN OUT L--R
edifier, use 2pcs of RCA plug into PC input

single a.k.a. 1 way speaker.
only 1 piece of speaker cone to cover low--mid--high frequency & instrument & vocal & backing chorus etc..
very good at low volume, u hear full range sound like headphone
very bad at high volume, the cone become distort & bunyi pecah like old laptop speaker.

2 way, got a cone and a tweeter.
audio is separated by crossover, so that bass to vocal mid is the main cone coverage, around 2000hz & above is tweeter's job.

3way, got sub, got main cone, got tweeter.
crossover separate low--mid--high.
sub handle from lowest note to 150hz (pc standard)
main cone play everything after sub.
tweeter play higher Hz after main cone.

buy a headphone adapter like the picture shown below and plug it to your "phones" out


or

connect it via RCA with 2 "1/4 male to female rca" adapters like the picture shown below and plug correspondingly to your main left right out



I'd recommend you go with the 2nd option

Have you finally resolved that USB cable issue, and found the right cable? 

Then the cone can hardly move (very tiny displacement only) resulting in very tiny sound and/or almost inaudible sound...

One single speaker/driver trying to cover the entire (audible) audio frequency spectrum. Usually these single full range speakers/drivers in reality cannot cover the whole range adequately/properly (weakness on the lower and upper frequency regions)...   

First of all, get a pair of these adapters...

Then simply use a RCA stereo cable to connect to the active speaker system inputs. Its that simple. Other than that, can use DIY cables if you cannot find those adapters...

If you had tried many cables without success then there could be some factors, such as the size of the USB connector core (as mentioned before in another thread) and/or some problem on your USB audio device (possibly loose contact which the connectivity can be affected by the core size, and/or possible cracked solder joints inside). If those I've recommended don't make USB cables, then can try me (PM me if interested)...

Headphones are really good examples of small/tiny speakers. That Aune X3 is considered small compared to other usual HiFi studio speakers, plus it requires some power to get the cone moving. You can do the maths, 15W (speaker) divide by 0.1W (line out) is 150. In other words, you need to amplify the line out power by 150 time to fully maximise that speaker. And that is the main job of audio power amplifiers...

You've already seen them. Edifier R1600T III and KRK Rokit 5 are 2-way speakers (have tweeter and woofer). Edifier Studio 7 (a.k.a Edifier R2700) and Edifier Studio 8 (a.k.a Edifier R2800) are 3-way speakers (have tweeter, midrange and woofer)... 

Lots of tutorials on the web, as well as on Youtube...

yup,  RCA to mono phono.

usb is same as printer cable can easily buy from pc shop.


r1600 is 2 way, u can see the obvious 2 separate piece.
ini 3 way, u can see the obvious 3 piece of small--medium--big size speaker. port is not counted.

For your information, I have quite a number of those USB printer type cables but mine comes from old school USB external 3.5" hard drives and USB external 5.25" CD/DVD drive. And those were yesteryear cables (have to dig them up back if required). Not sure what's the difference between ye olde cables and the new ones nowadays (in terms of connections and quality)...

That Edifier R1600T III is an active speaker system, which means it has its own power amplifier inside to drive the woofer and tweeter (each driven separately as it uses bi-amplifier design)...

Yups, that one is a 3-way speaker also... 

U never mention la bro, mana i tau dah beli byk cable
well, have to find high quality one, like my akai midi controller, only stable when using ori usb cable.
get from lex, easy senang.

generally, high watt got more force to push magnet  =louder.
less chance of clipping & distort etc.. Electronic formulae that require sifu2 sekalian to explain

As mentioned earlier, have to dig them up (packed them up in a box somewhere). I would strongly suggest bringing your audio device to test the USB cable first, as do you not want to end up with another useless USB cable again. May also check the reason for being "picky" about USB cables...

Differences are too many including pricing, brand, appearance (such as color, texture, shape, etc), size (dimensions), weight, features (such as remote control), volume and tone control location, etc. Technically the main differences are...

Edifier R1600T III
- Class D (digital) bi-amplifiers
- single power supply
- 4-inch woofers
- 30WRMS per speaker, total of 60WRMS
- Unbalanced RCA inputs only (standard connection)

KRK Rokit 5 G3
- Class AB (analogue) bi-amplifiers
- split power supply (each speaker has its own power supply)
- 5-inch woofers
- 50WRMS per speaker, total of 100WRMS
- Unbalanced RCA inputs as well as balanced TRS and XLR inputs (professional grade connection)

Obviously with bigger woofer on the KRK Rokit 5, can expect better low frequency response. That Edifier R1600T III on the other hand is considered as a very affordable high quality studio monitor. Of course, immediately those differences are reflected in the pricing as well (as that KRK Rokit 5 costs about 3 to 4 times more than Edifier R1600T III). 

Anyway, here is a review: Gecid.com Ukrainian IT-portal: Logitech Multimedia Speakers Z240 review that clearly highlights/demonstrates the problem of using single full range drivers. Can see from the frequency response graph the main weaknesses of using a single full range driver as I've already mentioned earlier... 

If you got more budget, give R1800TIII a try, just reach Malaysia last week.
