Wireless models of loudspeakers are quite popular these days. That is because the wireless technology offers more flexibility in placing speakers then regular models which require running speaker wire all over the house. In this blog post, I’m going to offer some tips and also reveals some secrets that manufacturers of these wireless speakers do not want you to know.
One of the misconceptions of wireless speakers is the fact that many speakers actually are not truly wireless. That is because wireless models require an internal amplifier as well as a receiver in order to reproduce the music and drive the internal woofer and tweeter. Therefore wireless speakers by definition require power. Power can be received from a power supply or internal batteries.
An internal power supply has to be connected to a wall outlet. Usually the connecting cable between the power supply and the plug that fits into the speaker is fairly short. Therefore, a wall outlet needs to be in close proximity to where you plan on using the speaker. If you’re planning to use the speakers outdoors, then chances are that there won’t be an outlet nearby. In that case you might prefer to purchase speakers that have internal batteries. Batteries offer the highest amount of flexibility. Unfortunately, batteries only last for long. Therefore, you will be stuck having to either swap batteries which can be expensive in the long run or having to recharge the battery pack every so often.
Also, the limitation of speakers that work from batteries is the fact that the internal power amplifier requires a substantial amount of current. Batteries typically are not able to supply enough current to drive the speakers to high volume. The wallboard power supply, on the other hand, is a better choice since it allows the speakers to run continuously and also provides more current.
Another problem that wireless speakers have is the limited wireless range. Bluetooth wireless models typically are restricted to within 50 feet. Other wireless models can go up to 300 feet. Therefore the type of wireless speaker very much depends on where you will be placing the speakers relation to the transmitter. The farther away you need to transmit more you have to be concerned the range of the transmission.
Wireless speakers that use digital transmission, will usually drop the signal as soon as speakers are outside of the wireless range however, models that utilize digital technology are more robust against wireless interference which can be caused by other devices. So the type of speaker which you choose will depend on the range as well as the wattage that you require.
