Subwoofer to add on to Logitech z506?

[Ironarmygeneral]

I would like to add another sub and MAYBE a few more speakers (I have eleven as of now with three subs, two subs suck), and I would like to run them in a compatible configuration. I have a bunch of audio jack splitters (some 4mm and some 3.5mm) already, so if I need to run them separately from the z506, I am totally cool with that. Are there any subwoofers that are pretty good, (Maybe even THX qualified), that I can get for no more than $100? Requirements it needs:

- RCA output, or regular audio output if it comes with speakers. No more than two satellites.)
- RCA and/or regular audio input
- Bass control

What I prefer if possible:

- THX qualified
- Large, bigger than the z506 subwoofer at LEAST
- Downward facing driver

That's it. I dunno where you all got the idea I wanted a new PC sub... I never said that.

"I would like to add another sub and MAYBE a few more speakers..."

And where exactly did you get PC speakers or even PC out of this sentence at all?

Nothing stated otherwise.
However, the z506 was mentioned.

Anyway...you've been given suggestions, both cheap and expensive
I'm out.

Gods. I have no idea why I'm getting f-ing bashed here. Yeah, the z506 was mentioned. So? What does that have to do with computer speakers?

As you seem to think that a high quality subwoofer can be localized, congratulations if you can discern the direction of sounds at or below 80Hz, or perhaps congratulations that your ears are much farther apart than most humans. I, like most humans cannot, although I expect that my dogs can, it is basic auditory physiology. Kudos to your canine ears.

Read your earlier posts and you will know:

"Dude, I have some of the best speakers I've ever heard. But I just bass. To me, the more, the better. The only thing that sucks are two of my subs. Which is why I want a new one to run with dual subwoofers. If you were able to, I'd ask ya to ask any of my friends that have visited my house... my surround sound is f-ing gorgeous sounding. Clear as day. Almost $2,000 worth of a computer and $1,500 worth of speakers. Please don't judge and just help me... II really want another sub."

The problem is that what you want is just not available at your price point. If you really want high quality sound, it is very expensive and subwoofers are no exception. In my experience really good subs are expensive and good amps or receivers are necessary.

When just those frequencies I mentioned are played, most people can localize them, this isn't a "golden ear" claim, it's around 40-65Hz that they finally become very hard for most people inside a room (outdoors it can go lower). But as I pointed out, that was mostly a secondary issue which usually doesn't matter for the reason I mentioned. Balance throughout the main listening area is the primary concern and I gave the specific reasons why multiple subs matter for sound quality based on physics.

@OP:

The title of your thread is "Subwoofer to add on to Logitech z506" with no mention of an AVR, receiver, or pre/pro/amp not to mention what speakers/subs you have. It very much sounded like you were just throwing "pc" speaker systems together. But you finally got around to explaining what you were doing.

Regardless, ssddx gave you a suggestion which I also agreed with.
