The jbl control series can be regarded as industry standard speakers. Featuring all the high performance of the standard version, this self-powered, and almost free floating, speaker system will ensure the control 1's re-affirm their position as the speaker of choice for so many purposes. Simply connect the wireless transmitter to the back of your audio source (dj mixer, hi-fi system, mp3 player etc) via a simple phono connection, plug the speakers into the mains and your good to go. The speakers are self-powered so no amplifier is required, and they can be placed 30 metres away from the audio source. Included wall brackets and a remote control with mute and volume control eradicates any inconvenience from the distance between your sound source and output. With a 4" low frequency woofer, a 3/4" polycarbonate dome tweeter and high performance dividing network, you still get a very impressive jbl sound. Thanks to the included remote control, 30 metre roaming capability and the fact that the control 1's are incredibly durable, potential uses of this system are unlimited. Wired systems can be a thing of the past, your audio equipment no longer needs a mile of cable to reach your carefully placed speakers! Connect to your computer and enjoy your music anywhere in your home, house parties can venture outside with no risk to your equipment, mobile dj's can expand an indoor show outdoors, venues can still offer smokers the pleasure of audio whilst punters obey the new smoking regulations. All the simplicity of plug and play, all the quality of jbl, all the convenience of a wireless system and best of all THE PRICE
