Some rambling on....
Bitflipper had it right - good studio monitors are
neutral - by definition. The reason for this is that a neutral speaker doesn't sweeten, gloss, or otherwise mask any imperfections in the source material. This does not mean the speakers are 'cheap', it's just that the speaker are made to be deliberately (and accurately) flat. They may look like bookshelf speakers, but they are not.
The problem with non-monitor speakers is that they aren't necessarily flat, they sometime have all sorts of gimmicks to sweeten their sound, even so-called estoric, 'audiophile' speakers.
If it sounds good on a studio monitor, it's gonna sound good on consumer speakers.
