Live Sound Speakers
Speakers are everywhere in hotels, houses of worship, restaurants, cars and even in your ears. Many kinds and types. Today We are talking about speakers used to amplified live sound events. In other words: Pro audio speakers. A sound system has three main parts and speakers are one of those. They come in different sizes, shapes depending on the intended use. Manufactures like Turbosound, Yamaha, DAS audio, RCF, QSC are well known and make high-quality professional speakers. Based on the amplification method we can say speakers come two types, powered and non-powered. They are also called, active and passive respectively. The most popular sizes are 8", 10" 12" and 15". Bigger speakers are called subwoofers, and their sizes are from 18" to 30" for big sound reinforcement events.
Powered & non-powered speakers
Powered speakers have the amplifier built-in in the speaker. The manufacturer matched the speaker to the amplifier, so you don't have to do it. Powered speakers are ideal for those new in live sound. They are easy to set up and connect to the sound mixer with one microphone cable. Anyone can do it. Powered speakers are great for trainers, portable churches, DJ's, hotels, outdoor events, and house parties. The size and shape Most powered speakers have a two-channel mixer in the back. If all you are doing is connecting one or two microphones, no external soundboard is needed.
Speaker types, by use.
Three types of speakers come to mind. Main speakers, subwoofers, and monitors. Main speakers deliver most of the sound to the audience. Subwoofers reproduce low frequencies only and are the soul of music. There is no good sound without subwoofers. The Kick drum comes alive with subs. Monitor speakers are intended for the musicians to listen to what they are playing.
Line Array speakers
Have you ever been in a concert? Did you see those prominent speakers hanging of a structure? Those are line-array speakers. Their purpose is to give the audience loud and clear sound anywhere in the venue. To achieve this, speakers are hung on one on top of the other one forming a big tower. Line array speakers were reseved for big events until a few years. Companies like DAS Audio, CRF speakers, brought the line array concept to smaller scale events. Today many small bands, churches and rental companies can cover more audience for less. A favorite line of speakers is the DAS Event series. Available in 8" 10" and 12".
