Depends on what you spend. Good studio monitors should have fairly flat response across the audio spectrum and most tend to be Near-field monitors which sound absolutely great when you are positioned in front of them as you would for mixing, but don’t sound quite as good when used as a general room speaker. Mind you they are often still better than many peoples setups just the same. The ones that are not Near field can work even better for a general audio situation but tend to cost even more.

Some studio monitors like the popular KRK series are not flat response and are a bit bass heavy.

Speakers (of any kind) can vary tremendously, which is why it's nice to be able to compare them. Guitar Center carries more than just guitar-specific items, which is why I thought it would be helpful to mention them; it's not something many people are aware of. I would never consider guitar speakers for general purpose use.
