While purchasing wireless speaker products, there are a couple of things to watch out for to steer
clear of unwelcome surprises as well as to make sure that you are getting the best bang for the
buck. I am going to offer various guidelines to adhere to whilst choosing the ideal speaker.
Wireless loudspeakers are tempting as they eradicate the loudspeaker cord and eliminate
requiring an external amplifier. Just imagine setting up a pair of loudspeakers at your deck in the
blink of an eye without a big cable clutter or sending audio wireless throughout your home.
Regular loudspeakers require an external audio amplifier to be driven. On the other hand,
cordless loudspeakers have their own built-in power amplifier. For average to high audio power
amplifiers, those speakers commonly need to be plugged into a power outlet. This means that
these speakers can only be positioned in locations that have power. This normally is not much of
a predicament if you plan on putting speakers in a different room of your house. However, to
eliminate the power cord, a number of cordless loudspeakers are powered by internal
rechargeable batteries. The downside is that following each use those have to be recharged.
Moreover, a number of products are quite heavy making it challenging to move them around.
Batteries also tend to age and need to be changed every so often. Depending on your application,
you want to select loudspeakers with the right audio power that is enough for your setting. If you
are planning to use your loudspeakers outside, be sure to pick speakers that have a waterproof or
at the very least rain resistant housing. Normally the maker would indicate if its speakers can be
used as outdoor loudspeakers (read this on the subject of wireless indoor outdoor speakers).
Moreover, make sure the transmitter has the audio inputs that your audio equipment provides, the
more inputs the better. Some transmitters provide a speaker level audio input. This sort of input is
regularly necessary whilst attaching the transmitter to the rear loudspeaker audio outputs of a
surround receiver to be used for wireless rear loudspeakers. A lot of surround receivers do not
offer dedicated line level audio outputs for rear loudspeakers. If you have an iPod or iPhone you
may want to select a transmitter with a built-in iPod cradle. A lot of transmitters will at least have a
line-level audio input. Ideally the audio input may be adjusted in volume such that the transmitter
may adapt to different audio sources.
A number of of the most modern cordless speakers utilize digital audio transmission typically
either at 2.4 GHz or 5.8 GHz. These kinds of speakers eliminate the audio distortion and noise
that are inherent to speakers which use analog audio transmission, normally at 900 MHz. With the
growing range of wireless products, there is more and more cordless interference. Latest wireless
speakers typically use some sort of error correction method. This technique allows the
loudspeakers to be able to tolerate interference with no audio dropouts.
If possible, attempt to set up a listening test. Be aware however that the sound quality also
depends on your listening environment. Various wireless speakers have adjustable trebble or
base. If you can't part with your existing speakers or cannot find a cordless loudspeaker that
sounds just right, you can go with a wireless speaker kit. These kits have a transmitter and one or
several wireless receivers. These receivers incorporate an audio amplifier and may attach directly
to your old loudspeakers.
