I am in way over my head. I have hooked up two LSR 308's and an LSR 310 Sub to my PC via an HTO Striker 7.1 sound card. The 308's havea an XLR aoutpu to the sub, and th en I took the sub from XLR to 3.5mm for the connection to the sound card.
Is this even close to correct? The sound doesn't sound "full" to me, as it is.
What have I done wrong?
Thank you, in advance, for your help.

I took a look at pictures of the back panels of the LSR308 and LSR310s.
First of all, make sure your sound card is set up to output a 2-channel down-mix through the 3.5mm jack. You say it' a 7.1 sound card, so some configuration may be required.
To hook the 3.5mm stereo (TRS) jack to the LSR310s L/R inputs, you need something like the adapter cable shown above. Follow the link below.
(If by some chance you instead used a cable that adapts a 3.5mm TRS to a single XLR cable, it would indeed sound very weird. It would essentially be playing the difference between the left and right channels.)
To hook the LSR310s L/R outputs to your two LSR308 speakers, you need two standard XLR cables. I assume you already have that set up correctly.
Assuming that the 3.5mm output is a standard consumer line level, you probably want to set the input sensitivity of the LSR310s to -10dBV. The other setting (+4dBV) is for a typical balanced input. I'm actually not sure if the LSR308 should be set to -10dBV or +4dBV in this configuration; it depends on how the LSR310s works, so check the manual.
Could you describe the outputs on your sound card? Do you have left and right RCA outputs? Do you have a single stereo 3.5mm output?
If you have a single 3.5mm output, then you will need a 3.5mm to RCA adapter. http://www.amazon.com/Plated-Stereo-Female-Adapter-Splitter/dp/B0146L3VDQ/ref=sr_1_9?ie=UTF8&qid=1456032426&sr=8-9&keywords=3.5mm+to+RCA+splitter
Thereafter, you will need a pair of male RCA to male XLR cables. http://www.amazon.com/Seismic-Audio-SAXFRM-2x5-Patch-Cable/dp/B00AFEMMVQ/ref=sr_1_1?s=musical-instruments&ie=UTF8&qid=1456032294&sr=1-1&keywords=xlr+male+to+rca+male
Be certain to get these in the appropriate length! They need to travel from your PC to wherever your sub may end up. Note, this maybe much farther away from your PC than your sub is now.
Then you will need a pair of XLR female to XLR male cables. Again, be certain to get these in the appropriate length! Note, your sub maybe much farther away from your speakers than it is now.
If your sound card has RCA output, plug your male RCA cables into the RCA output and then plug the male XLR ends into your LSR 310's inputs. (If your card lacks RCA outputs, plug the adapter into the 3.5mm plug and then plug the cables into the RCA outputs.)
Then, plug your female XLR connectors into the output ports, and run the cables to the appropriate left or right speaker.
Make sure your sub and both speakers are plugged into AC outlets.
Look on the back of each speaker and set the volume knob to the 12 o'clock position. Set the sub's volume to the 12 o'clock position as well. Make sure the sub's crossover setting is set to 80Hz. Set the input sensitivity to -10dBV. Note also there is a polarity switch.
These are your initial settings. Using these settings, move the sub to various locations in your room until you find the best response for your setup. Be creative, well off to one side of the room may be the best for your setup. During this process, be certain to toggle the polarity control and listen for a bit with it in each position at each location. It can make a surprising difference.
Once you've found a place for the sub, I recommend orienting it so you have easy access to the back panel controls and connections. Then you can start using the controls to fine tune your sound. A little bass boost goes a long way, as does a little bass reduction. If the system is too quiet, then turn up the volume on the speakers and the sub, making sure to match all three for the flatest output. Have fun!

I've attached a photo of my sound card. The Line In is the one powering the system, at this point. I have all the adapters to get it from 3.5 to XLR in sub. Sub to speakers is XLR cable.
I've also adjusted the sub and speakers according to your instructions, but the sound level was too low, so I bumped them all up. Even on top volume, the sub isn't sounding right. It's not prominent enough. I've tried the two polarity settings, but haven't noticed any difference. The sound coming from the speakers still sounds rather hollow, but not on every song.
To complicate things further, I have a DAC, which may or may not make this easier. I don't know.
I appreciate you, and everyone, who is helping me. I am trying to achieve a quality sound set up, because I enjoy music so much. Unfortunately, I am at a disadvantage, because I know very little about the set up. But, I want to learn.
Thank you.
One more thing to add to my post below. You say you have a DAC. What DAC is it, and is there a reason you prefer to use it or not?
You say: "The Line In is the one powering the system" . Do you mean you have attached the sub to the Line In jack on the sound card? If so then that's your problem. Plug it into "Front" instead. WARNING: Turn down all volume controls before you do this. You've probably cranked everything up so high to hear whatever crosstalk was leaking into the Line In jack.
This connection is shown on page 14 of the HT Striker 7.1 manual (link below). See "Connecting 2 Channel Speakers".
I perused the manual a bit more, and you may indeed have to do what I said before about configuring it for a 2-channel system instead of multi-channel. See section 4.2 at the top of page 19. It looks like you need to make sure "Analog Output" is checked and the "2" speaker box is selected. It may detect this automatically from the fact that you have nothing plugged into the other outputs, but it's worth checking.
Let me know if you have further problems.
I apologize. I checked it again, and it is coming through FRONT channel, not Line In. I'm old. Can't see like I used to!
The Striker settings are correct at 2 channel analog.
I have a Dragonfly DAC. I have no experience with a DAC, but I had access to this. I figured it was something to try, if I ever went to a 2.1 system.
My previous set up, for many years, was the Striker and Logitech Z-5500 5.1 system, for what that's worth!
Try using the Dragonfly instead of the sound card. Does it sound about the same as the sound card, or does it sound very different? If it sounds very different then there's some issue with the sound card.
It doesn't sound any different, to me. Actually, it sounds better from the sound card, if anything.
Were you able to work out the issues, and if you were, what did you do?

I've moved the speakers to a position to my right and left front. I cannot seem to get any bass kick from the sub, positioned to my immediate left, under the left front speaker stand. I've tried positioning it off to my right, to no avail. It simply has no "ass." The volume of the sub is on max,and the other settings are as suggested in this thread.
The speakers themselves are very, very sweet positioned as they are. I need more depth of sound, from the sub.
Suggestions, please?
I reluctantly admit that the sub did sound better when located between the two speakers when they were behind my listening position. It's just going to be a wiring nightmare to put it there, and run the speakers back to it, and then forward, again.
Try this. Set the output level of the sub to match your speakers, then move the crossover setting on the sub from 80Hz to XLF. That will add a little more punch to the bass.

That's a difference that made a difference.
I believe, with equalizer tweaking, I am there.
If you've got a monitor in your room, load up this video, switch it to full screen, crank up the volume on your speakers and enjoy more than fifteen minute of pure adrenaline.

Wow!
Sweet!
If you are happy, settle in and enjoy your new speakers. I still worry that you may have your sub in a bass null room mode if you need to use the XLF setting. Have you tried simply sticking the sub in the various corners of the room to see what happens?
If you can, make sure the tweeters on your 308s are close to your ear level. If the 308s are too far apart you won't get a center image. Fiddle around with them for a bit and you may find a spot where the sound stage "locks in." You'll know it when you find it.
Have fun!

"A difference which makes no difference is no difference at all." - William James
Well, the post has two black lines, so I'm OK there. I think the connection is as it should be, and the problem lies in my positioning of the speakers. I have them set up behind me, in the corners of the room. The room is about 12'X12'. I'm used to 5.1, and being surrounded by sound. I'm going to move the speakers to a position in front of me, and I think with the current wiring, I will be good. I've moved the sub to several locations, and it does make a big difference. I think by moving the speakers, everything will be right.
I appreciate all of you for taking the time to help me. You gave me the confidence, and the tips, to get this done. Thank you.
In his first reply to you, ephemere posted a picture of what we're guessing is the type of cable you are using to go from the sound card to the sub. Could I ask you to switch off the sub, then pull the 3.5mm plug from the sound card and examine it? The plug should have TWO black bands on it as shown in ephemere's post. If it only has ONE black band then that is likely the issue. You need to have a "Tip, Ring, Sleeve" jack in order to get stereo output. If you have one black band then you have a "Tip, Sleeve" jack and will only be getting one channel.
Be certain your 308s are on their -10dBV settings. Also set the high frequency and low frequency "trim" controls on the speakers to the center setting.
I also agree that it may be best to first set up the speakers without the sub in the mix. If you simply don't like the sound of the 308s, adding a sub won't improve things.
By the way, where do you have the 308s positioned?
Good Luck!

"A difference which makes no difference is no difference at all." - William James
Then I suggest doing what E-Stat suggested -- connect the sound card (or DAC) directly to the mains, and take the sub out of the system. Make sure you put the speaker switch to -10dBV.
Let's start from the source. The signal from the sound card goes first to the sub and then to the mains?
Yes, out from the PC to via one 3.5mm wire to a split. The split goes to the two sub inputs. The two sub outputs are going to the speakers via XLR cable.
to the sub input? To TRS/Phone plug or XLR?
I read the manual and that is the recommended way - I would typically drive the mains directly first.
To XLR. I was mistaken. It's coming out of the sound card through FRONT channel, not Line In.
I might try bypassing the subs and see if you get the same results with the mains alone.
You may have an impedance mismatch. Typically sound cards are not designed to drive power amps directly.
I run the analog outputs of the office server to a high level input on an integrated amp which provides extra drive.
