All You Need to Know about Bookshelf Speakers and Wireless Speakers
Wireless speakers are very similar to traditional wired loudspeakers, but they transmit audio signals using radio frequency (RF) waves rather than sound waves over audio cables. A Bookshelf speaker is a compact loudspeaker, generally sold for consumer-grade home audio applications as part of a shelf stereo pair or a home theatre package that is compact in size and intended to be placed on a raised surface, such as a bookshelf. Everyone, from recording studios to home theatre enthusiasts to hardcore audiophiles, has a place in their life for bookshelf speakers. Small speakers deliver great visual appeal and fit into small spaces. Combine a pair of bookshelf speakers with a subwoofer and you have a system that is booth roomfriendly. Bookshelf speakers neednâ€™t necessarily be installed on a bookshelf. They are normally installed on stands or mounts. They tend to be front ported or fully dynamic in configuration. Because of their small size, they are known for their ability to display very nicely, but they rarely produce deep bass. Thatâ€™s why they are often also matched with a powerful subwoofer to get a full range sound. Bookshelf speakers are also used frequently today as side and/or rear speakers in 5.1 and 7.1 speaker configurations. Wireless speakers are composed of two units: a main speaker unit combining the loudspeaker itself with an RF receiver, and an RF transmitter unit. The transmitter connects to the audio output of any audio device, such as hi-fi equipment, televisions, computers, mp3 players, etc. An RCA plug is normally used to achieve this. The receiver is positioned where the listener wants the sound to be, providing the freedom to move the wireless speakers around without needing to use cables. The receiver/speaker unit generally contains an amplifier to boost the audio signal to the loudspeaker; it is powered either by batteries or by an AC electric outlet. Batteries may last for three to four hours. Some wireless speakers operate on rechargeable batteries. Different types of Wireless speakers are designed for specific needs: Stereo speakers can deliver both Left and Right stereo channels in a single speaker. Speakers designed specifically for outdoor use have a robust casing; manufacturers claim these are weatherproof. Home theatres utilize a specialized set of speakers in which only the rear speakers are wireless, while the front speakers are wired.
