does a subwoofer kill stereo sound?


I was wondering whether adding a subwoofer to a pure stereo system would cause any harm to the soundstage and other features of the system. What are your experiences? Should one buy a subwoofer to complement a great bookshelf pair (that may be lacking some bass) or necessarily one would have to buy a new par of speakers with deeper bass?

When I shut my sub off, the stage gets narrower.

Sub is playing well with panels.
Hi, again, Mac.
Agreed about setup. I spent about an hour doing first placement of sub.
I listened over a period of the next few days making 'little' adjustments. No joy and the bass remained 'thick'.
Finally, I turned the x-over all the way down. That is an indicated 30hz, but who really knows?
I turned it UP until I heard it again than down sightly. I adjusted the vol. again than the crossover frequency again. It's been untouched in a couple months.

the variation between recordings is a far bigger problem now than any possible improvement to the basic setup.
My final adjustment? x-over under 40hz and the sub 1 foot from a side wall and nearly 3 feet from the 'front' wall. The sub is in the same plane as the panels. When I rotated the panels around, I shut off the sub and when I had the panels properly adjusted, turned the sub back on and my bass disappeared. OOOPS! Flipping the phase switch on the sub restored the bass.

If I had the $$, time and inclination, I'd work on NOT running my panels full range. I suspect there are additional benefits in that direction, but also a whole new learning curve.
OhJoy,
Isn't bass mixed to mono below.....say 80hz?
Also:
Given that bass wavelengths are longer than the longest dimension of MOST rooms, I'd say a sub was not locatable, eyes closed.

In large rooms, this may change.
