Xonar STX + M-Audio AV40 + Polk PSW10 sub...How to connect it all? Update: Connected!

post #1 of 22
Thread Starter 
I have an Asus Xonar STX sound card, a pair of M-Audio AV 40 speakers, and a Polk PSW10 subwoofer, and I have no idea how to connect them all.

At first, I was just going to connect the RCA out on the STX to the sub, then plug the speakers into the sub with speaker wire. But then I read that this is a horrible idea that will result in death or damage to the AV40s.

So now I'm sort of clueless as to what to do. My current plan is to get Y splitters for the RCA outs on the STX, and then run RCA cables to the AV40s and the sub separately from the Y splitters.

Any help is appreciated. In providing advice, please treat me as if I were a mentally handicapped monkey raised on a steady diet of sewer water and leaded paint chips, because I'm an audio noob and I have no idea what I'm doing.

Thanks.

wow.............thats tough:headscrat

not letting you down friend , i did some search and found this:

_What you have is a subwoofer with a passive connection. What your stereo expects you to have is a powered subwoofer that has either a built in amplifier, or a subwoofer that is connected to an amplifier.

First off, you are probably wondering if you can connect the subwoofer to the RCA output with some kind of adapter. The answer is yes, BUT the volume that comes out of the sub is so low that it is barely audible, if at all. You won’t damage anything, you just won’t be able to hear any sound from the sub and it will be useless.

The reason for this is that the RCA subwoofer connection of the back of your stereo is meant for an a subwoofer that has an amplifier either built in to it, or a subwoofer that is connected to an amplifier. Either the subwoofer with the amplifier built into it connects directly to that RCA port (the subwoofer it’s self will have a connection for an RCA cable), or an amplifier connects between the subwoofer and the stereo through that RCA port.

But don’t worry, all hope is not lost, you have two options.

OPTION A) What you could do is go to your local Radio Shack or Walmart and buy a cheap amplifier for your subwoofer. If you have money for something expensive, then I suggest just buying a whole new subwoofer that has an amp built in.

OPTION B) The other option, and the one I tend to use in these situations is to connect the subwoofer to either the left or right speaker output, just like you did for your other right and left speakers using normal stereo wire. Now you are probably wondering, if the right and left speaker are already connected to the right and left speaker connections on the stereo then how can i connect the subwoofer to one of these?

Well if your stereo is a good enough quality one that it has an RCA port for a powered subwoofer, then chances are it actually has at least 2 connections for the right speaker and the left speaker. One group of connections will be for an entire surround sound system. You will see the front left, front right, back left, back right, center, subwoofer, and possibly a few other connections.

There very well may be another two connections that are just plain old left and right stereo speaker connections, as you would see on any old stereo. You can connect your subwoofer to either the left or right one of these. You may have to play with your stereo settings to turn on those speaker output though.

This will work decently well, it will not sound as good as if you just went ahead and bought a powered subwoofer like your home stereo expects you to have. The subwoofer is built to only output low tones, thus when you connect to the right or left speaker connection, your subwoofer will only output the low tones from that connection and give you some bass, not great bass, but it should still enhance your movie watching experience.

_and one more thing about the Y splitter i read that its very BAD it might give you mono or even damage the main unit

hope that helped

This is good info. I'm trying to get this set up without damaging anything.

The subwoofer does have an amp though:

Polk PSW10 - Single 10-inch subwoofer with built-in high-current amplifier for big bass.

Does this change the analysis?

i have to say that there is always some danger in that operation cause usually adding a subwoofer to a stereo system requires a separate amplifier to power the sub. Without a separate amp, the sub can draw too much power from the stereo and throw off the sound quality

here a guide i`v found on some site:

1 Examine the back of your subwoofer and identify a single RCA-style input marked as either "Line In" or "LFE." Locate a set of speaker wire terminals marked as either "Speaker In" or "High Level In." There will also be a corresponding set of speaker terminals marked "Speaker Out" or "High Level Out."

2 Examine the back of your receiver for an RCA output marked "LFE" or "Sub Out." If your receiver has this output, proceed to Step 3. If your receiver does not have this output, proceed to Step 4.

3 Connect a subwoofer cable from the "LFE" or "Sub Out" RCA connection to the corresponding connection on the subwoofer. This directs the low-frequency information from your receiver to the subwoofer for amplification. It is the most common connection used with home theater receivers in which a channel of information is set aside for low-frequency effects.

4 Connect speaker wire between the speaker outputs of your receiver and the speaker inputs of the subwoofer. Go from "out" of the receiver to "in" on the subwoofer. Connect the right speaker output of the receiver to the right speaker input of the sub and then the left output to the left input.

5 Connect speaker wire from the "speaker" or "high level" outputs of the subwoofer to your stereo speakers. The subwoofer will filter out the low frequencies, amplify them, and pass on the rest of the information to the speakers.

6 If your subwoofer has a "low-pass" control knob, set it to 100 Hz and then adjust to taste as you listen. Setting it higher will send higher notes to the sub, whereas setting it lower will restrict the sub to the very lowest frequencies.

frankly you don't have to expect great improvement , this issue is very common in cars sound system and there is some difference between the two especially in the terms of powering management (Electrical impedance)

so i advice you to forget about it and maybe save money for a new 2.1 set
i do not want to freak you out, it might work , but there is some DANGER

Wow I literally just googled "subwoofer for AV40" and came across this thread. I'm in the same boat. Just got my AV40's last week and I'm craving more bass. I also happen to have a PSW10 but it's currently the home theater sub.

Given that the PSW10 would probably require more work than it's worth in this situation, are there any other powered subwoofer recommendations?

subwoofer's left and right speaker inputs (they will be labeled"Speaker Level Inputs" or "High-Level Inputs") and then from the subwoofer to your main speakers

no..

You can't have a powered input going to the AV40's at the back. The AV40's have an amp themselves. It doesn't make sense.

sorry for long speech i just making sure things are crystal clear redface.gif

that's for a stereo receiver and its not entirely correct. You have to set the speakers to large and switch the LFE off.
Stereo receivers have poor bass management and is set to cut off frequency too high (between 80-100Hz)
So you'll have to set the frequency between 50-60hz

For a cheap but not good solution get this:

It would be better to get an active splitter although.

eh? Don't you have a receiver or amp? Does the AV 40's have a LFE input?
