Whether you are relaxing in the garden, on the terrace, or by the pool, the experience is enhanced by music. Cambridge Audio's ES30 offers a surprisingly large bass extension thanks to its ported cabinet design and specially selected mid-bass driver. This injection molded cone woofer is mated to an aluminum dome tweeter for the crispest treble delivery. Both are carefully treated to ensure longevity even in humid or damp conditions. The durable cabinets are specially treated to prevent discoloration from UV rays, and the adjustable brackets and OmniMount fittings allow owners great flexibility in positioning. These speakers have been specially tuned by the acoustic teams at Cambridge Audio to provide the sound quality and clarity you would associate from a well made indoor speaker, allowing you to enjoy the quality of your hi-fi outside your home. Mounting brackets included.
