Energy ES subwoofers were designed to work best when used in smallenclosures. However, their electro-acoustic parameters are optimisedfor use in many different enclosure types; both in terms of typology(sealed box, reflex, bandpass, etc.) and in size, insuringextraordinary versatility and performance. The use of a long excursionmobile voice coil and high flux density double magnet have createdsubwoofers that can stand very high power with outstanding musicalityand bursting dynamics. The special anti-scratch finish and butyl rubberrings offer protection and an aggressive look.
