imposing from a price and appearance standpoint.
Bookshelf Speakers
Quite a bit smaller than their
floor standing cousins, these speakers are designed to provide a happy medium between sound quality
and space efficiency. While bookshelf speakers will lose some of the performance of a larger speaker,
their size makes them a popular choice for many rooms.
Satellite Speakers
In areas where space is at
a premium, satellite speakers are a popular choice. These are small, usually plastic, and are often
included in many cost-effective "home theater in a box" packages. Their small size and cost
effectiveness make them an ideal choice for smaller rooms or a budget system, but their sound quality
often comes up short when compared to higher quality options.
Recessed Speakers
Some companies
offer a type of speaker that uses the wall or the ceiling as an enclosure. In other words, these
"recessed" speakers put the empty space in those areas to work for you. You will need to consider a
few things for this type of installation:
A suitable mounting depth
—
Most speakers need 3-6 inches of space behind the wall or
ceiling. If you go this route, make sure there aren't drain lines or wires blocking the way.
A sturdy mounting surface — For this, properly installed drywall will usually provide a stable
area.
Wire access — Some high quality wire can be as thick as your finger. How do you want it run?
Is the wire you will be using code compliant? (See "Running Wires" section for more
information.)
Soundproofing — Things may sound great in one room, but can be irritating to those in the
next room. Proper treatment will cut down unwanted noise, as well as help your sound quality.
A working knowledge of your house's construction — Before you begin installation, know what is
hidden before you cut or drill! This will help avoid any costly uses of the word "oops."
Needed ToolsSome tools used in the installation profession can cost hundreds of dollars. However,
these tools can save hours of work on a project and allow a skilled installer to learn about a house's
construction without cutting into the wall. They also eliminate much of the risk involved in working near
electrical and plumbing systems. Here is a list of tools needed for speaker mounting:
? Stud finder
? Tape measure
? Level
? Drywall Saw
? Pencil
? Power drill ? Flashlight
? Speaker template
— usually comes with recessed speakers
? Wall probe
—
piano wire, etc
? Wire running tools
—
fish/carpet tape, flex rods, electrical
tape
Running Wires You'll have to get a wire from your speaker to your equipment. There are a few rules
you'll need to be aware of when it comes to running wires: The National Electrical Code (NEC) is a set
of rules that govern how wires and varying types of power are to be run in a building. These rules cover
both high voltage (outlets, light switches) and low voltage (phone lines, speaker wires, cable lines). Any
work you do MUST be in accordance with the NEC, as well as local ordnances for your city, county and
state. It's good to have a clear understanding of these rules before you begin. Speaker wire can be
susceptible to interference from external sources, such as electrical lines. The NEC dictates minimum
safe clearances for wires, but it is best to keep as much distance between your speaker wires and any
potential sources of interference
