Hi, I'm relatively new to messing with speakers, subwoofers, amps, etc. but am looking into getting a pair of bookshelf speakers and maybe a subwoofer and connecting it to my PC

So, let's say I have a pair of Micca PB42X powered bookshelf speakers and a powered subwoofer like a Dayton Audio Sub-800 which I want to connect simultaneously to my PC which has an ASUS Xonar DG sound card. How would I go about doing this correctly?

Or it would make more sense to get the Micca MB42X's (non-powered) with an amp like the ~$25 Lepai? Thanks

get this....you won't be disappointed with the sound... I have one hooked up to to some polk audio Monitor 45's and a polk 10" sub and it will blow away any off the shelf 2.1 computer speaker system...

only think that sucks is the RCA input for the sub won't handle a thicker RCA cable but I don't think it's a big deal...I created a thread about this awhile back...

sorry.. I have last year's V2 model..the link is for the newer V3....

Your soundcard looks like it has 5 3.5mm headphone jacks. Look for subwoofer out and L/R (left/right). Your speakers and sub are powered and accept RCA. You'll need to buy 2 or 3 3.5mm (headphone) to RCA jacks.

The question is whether the 3.5mm jacks on the back of your soundcard are mono or stereo for the L/R. They usually are stereo. So 2 adapters are what you'll need. It's very common and shouldn't cost you more than $5 total.

Yeah the sound card has a 3.5mm port for center-subwoofer, so I figure a RCA to 3.5mm adapter may work.

I was looking at the powered speakers as a step towards getting into using such speakers, rather than getting unpowered and needing a receiver/amp. I wasn't planning to get a subwoofer right away. I'm just not familiar enough or have much experience to know if such a speaker system will warrant the ~$300+ I'd need for a good 2.1 system, over just a $50-$100 'pre-made' 2.1 system.

My old Creative Audio 2.1 system is giving out, but it's only like a $30-$40 system which honestly has done just fine for me so far. It's just that since I'm replacing it I thought about trying out the world of 'quality' speakers and such.

Just note that you'll have to the use the PC to control volume as the control on the speakers won't adjust the sub and vice versa.
