Ceiling Speakers. A guide on how to choose the right ceiling speaker for your home. How ceiling speakers work and the best places to mount and use them.

Ceiling Speakers
In - Ceiling and in - wall Speakers are finding their way into thousands of homes, and it's easy to see why. They're
finally good enough for people who want really enjoyable audio, and discreet enough for folks who want to enjoy music
without having to see their speakers. So for many A/V fans, the choice isn't whether to get them so much as how many to
buy.

How they work: the basics
An in-wall speaker works essentially the same way as a regular speaker. However, instead of being inside a cabinet, it is
mounted in a frame and set into the wall. It actually uses the wall cavity as a large cabinet, giving you more bass than
you might get from a stand-alone speaker of the same size.
In - Ceiling Speakers work essentially the same way, except that of course it's placed in a ceiling. (For the most part,
in-wall speakers tend to be rectangular, and in-ceiling speakers tend to be round.) Almost all in-ceiling and in-wall
speakers have paintable grilles, so you can really camouflage them in your walls or ceiling.
Using in-wall and in-ceiling speakers
Different kinds of rooms tend to be used for different kinds of listening, and speaker recommendations are going to vary.
For example, in a family room you might sit in a specific place to hear music or home theater sound at higher volumes. In
that case, the biggest, best-sounding in-wall speakers you can afford, positioned at ear level when seated, are going to
be your best bet.
A kitchen or dining room, on the other hand, is a place where you might want low-key sound distributed evenly throughout
the space. An array of unobtrusive in - Ceiling Speakers or in - wall speakers is a great choice in that case. And a small area, like
a bathroom or hallway, is often a place where speakers are just used for background listening. Stereo-input in-ceiling
speakers are recommended for rooms like these.
Deciding between different speakers
In general, if you want a lot of clean, detailed sound in your room, you need to choose the best speakers you can afford.
Larger speakers often produce louder, cleaner sound than smaller speakers. However, that's too loose a generalization to
base your choice upon. The factors you should really be looking at are:
* Frequency response. The range of human hearing is about 20-20,000 Hz. A frequency response specification tells you what
portion of that range Ceiling Speakers can play. A speaker with a frequency response of 50-20,000 Hz handles a wider range and
offers deeper bass than a speaker with a frequency response of 65-20,000 Hz.
* Power handling. A ceiling speakers recommended power specification usually tells you at least the maximum amplifier power the
speaker can handle often minimum power handling info is included as well. A ceiling speaker with recommended power of 20-100
watts is well-suited to an 100-watt RMS receiver, for example.

Flexibility issues
Also consider flexibility issues. Many in-wall and in-ceiling speakers come with swivelling tweeters, so you can
angle your sound toward a preferred listening spot. Some speakers also come with bass and treble tone controls that you
can access simply by popping off the speaker grille! Finally, you'll need moisture-resistant in-wall and in-ceiling
speakers if you're going to be placing them in a humid area, like a bathroom or kitchen.
