Shouldnt be a problem if the sub is powered. Its a simple lfe out of the receivers preout to the sub. If the sub isnt powered make sure the specs of the sub fall within the allowable specs of what the receiver supports. I personally wouldnt do this though.

Adapt computer sub to receiver?
Hi all.
I have a set of Klipsch ProMedia 2.1s. I am looking to add the subwoofer from the 2.1 to my receiver, a HK AV-135 (RCA out for sub).
The subwoofer (powered) specs are:
FTC Rated Subwoofer: 50 watts @ ≤ 7% THD, 40 - 100 Hz
Max Burst Power*: 200 watts @ ≤ 1% THD (Note: all channels driven)
The speaker system is set that it takes the stereo output 1/8" from a computer sound card and routes it to the satellite speakers through subwoofer pin receptors (left speaker has control pod for speaker power- not sub power, but a subwoofer adj level) and the sub. The sub has a preamp in through DIN plug.
I've been on the Klipsch forums, and through other threads I know it can be done, but it's really dead there. So I'd like some advice about how to do this...
My thought is: subwoofer in

The sub is powered.
But there is not direct RCA-type input connection-- just that DIN input which covers stereo sats and sub.
A LFE out is just the sub Frequencies + .1 for surround setups? Would I just use the sub out if I don't care about surround? ANd it should not matter if the sats are hooked up?

I am familiar with that system, and I believe you can just (disconnect the sats), keep the control pod, and connect the mono RCA (by way of appropriate converters) to the stereo mini input. Should work fine, I did the exact same thing with another system (but mine didn't have detachable sats, so you're better off). Works fine.
What are your mains? That Klipsche sub is weak, making most decent mains a better bass alternative. If you have tiny bookshelves, then you will probably extend your low end, but computer subs tend to have very high QTS and make all bass very boomy and very little extension. I'll assume that the 40hz figure is -10db since 50w RMS is not a lot of power and the small enclosure will limit low frequency efficiency. With that assumption, your likely to get -10db at 40hz from almost any larger bookshelf, and it is likely to be cleaner. Also, with multiple bass sources, you tend to even out room nodes, producing a more uniform bass.

Well, I have just built a budget system (HK AV receiver, Onkyo 6CD changer, speakers, wire and and stands) . My mains are Athena ASB2.2s, they're rated down to 50Hz. I spent a little over my budget, and have no additional money to buy a 'proper' sub. I am really just looking to take the low end off the mains.
I have never really heard any subs that people usually recommend in any audio board. What I do know, is how the sub sounded when I used with my computer. I thought it sounded nice, but then I have no reference point.
My wife would certainly not want the sub back in the house, would you really recommend not using it?

Your athenas claim +/-3db at 50hz. Together they have 2 6.5" woofers and each enclosure has more internal volume than the single Klipsche sub. The sub will probably have greater excursion, but I doubt that it has over twice that of your mains. Simple physics says that your mains are likely better at bass than that sub. Any audible advantage from adding such a sub will probably be due to an abnormal FR bump due to the sub's small size. However, your room size probably limits your audible bass substantially from any affordable source: it takes some serious amps to keep a room full of deep bass.
So, in other, don't hook it up.
