I concur that easiest would be to get a receiver. I force 2.1 from the PC to receiver (SPdIF as well). But at the receiver I have 4.1 running so my sub is enabled.

EDIT: On second thought, if you do not want to cancel the sub, go ahead and get it and see if it will work. At the very least you can pick up a decent receiver some time soon and get it working.

Correct.

Well you will need one less connector. lol It's getting an input from the sound card. Well for a real for a real subwoofer with the ability for a crossover frequency. You just use a 3.5mm splitter for your sound card and then a 3.5mm to RCA for the input on the sub. Just adjust the volume accordingly and then the crossover frequency. I would do around 100Hz. The crossover frequency is whenever the sub essentially "turns on" it will only play frequencies below 100Hz whenever it is set to that.

Using a receiver would defeat the purpose of buying a high quality sound card on a 2.1 setup.

Edit: I forgot to mention some subwoofers have low level inputs and outputs.

So instead of directly feeding the signal from the sound card you send it to the sub, then from the sub to the speakers. Much better way control a proper crossover frequency.

Bought my x-fi elite pro 4 yrs ago, not been a bad card except for the infrequent drivers, i use dolby digital live for all my music too so it had to be a digital signal from card to receiver, The receiver game me some good control and functionality with the card so would definitely recommend.
good luck with the project!

A soundcard alone will power the A2 but only to a point. Those speakers might be small but the got some oemf in them.

If you got a receiver Connect the subwoofer to the sub out of your receiver.
Connect your main speakers to the main speaker level outputs of your receiver.
Set the mains to "large" on your receiver.
Set the center channel to "small" on your receiver.
Set the rear channels to "large" or "small" depending on the bass capabilities of your rear speakers.
Set the Bass Out / LFE to "both".

you couldnt do this because input to the speakers is either the 2.5m jack or the left right phonos, speaker connections are different on a reciever.

Lol a phono to speakerwire adapter plug????

there's many issues here, firstly you cant really turn the phono cable into speaker wire to plug into the front L/R speaker connection of the reciever, and then you need to think that all these devices are gonna be requiring there own power, the sub needs power, the amp does, the speakers even do.

just seems too far fetched just to get 2.1.
We need a sub and speakers that are compatible, if we plug phono cable from amp to speakers were practically tellin the speakers to be the reciever when they should actually be the output,

OP's speakers got RCA in. Most receivers I have seen have audio out. Do not have to use speaker wire. If he gets a receiver that has audio out in red and white, he will be golden. And he can make it work with the sub he already ordered. No?
