The Hertz Energy ESF25.5 is an ideal solution for those who look for a subwoofer of compact size, yet providing powerful and engaging sound. At its highest excursion point, the Ultra Flat profile reaches 86 mm height for the 200 mm subwoofer, and 94 mm height for the 250 mm subwoofer, with a maximum power of 400 W and 500 W respectively. Care has been put into every detail of the design and building of these subwoofers, to ensure high mechanical quality as well as efficient thermal capability, to the benefit of bursting dynamics and startling power handling. Robust ferrite magnet motor assembly, pressed-paper cone, Back Vented Spider Support and copper voice coil, wound on aluminium former, are only some of the unique features of the Energy Flat subwoofers. The linear and solid design of the Energy ES F20.5 and ES F25 is enhanced by the ultra flat profile as well as by the Hertz logo on the dust-cap, making their cosmetics suitable to any installation.
