Sometimes you can find yourself in a position where cheaper is probably better and one of these situations will dictate the necessity, for example, for cheap speakers. Anyone living in a subtropical environment knows exactly how this kind of environment affects electronics.
For example a computer can be totally shut down or even refuse to boot up at all in the summer months when it is especially humid. One of the worst problem areas can be the speakers so sometimes it would be best to choose cheap stereo speakers.
This same idea applies to cheap in wall stereo speakers or cheap ceiling speakers. These are usually accessories of a home theater system and we as human beings rely more on our sense of sight than our sense of hearing. So if one is going to get a home theatre system and needs to know where to cut corners, better on the sound system than the visual inputs and parts of the whole ensemble.
Now keep in mind that cheap does not necessarily mean bad quality, it just means that maybe the competition on the market is working in favor of the consumer for a change. Shop around, see what is out there and what specials prevail especially during the Christmas season when many brands are trying to sell or promote their wares.
Either way if you do, as said before, live in that sub tropical environment you know how tempted you can be to just grab those badly functioning speakers and throw them out the window. So if eventually you do give in to temptation it is probably best they are cheap stereo speakers.
So remember sometimes cheaper is better depending on your circumstances and sometimes in some weather electronics can function badly no matter how expensive they are. Just ask the staff at your local electronics establishment and take time to find out which cheap speakers are best for your living space.
