The very first look upon these 25 kg heavyweights reveals that this is a potent representative of a modern subwoofer series. But by no means it is just a pure SPL subwoofer that can only play loud. Quite the contrary: The ESX Vision subs are also tonally very outstanding masterpieces which follow clean details down to the deepest frequencies without losing control. Due to their high efficiencies they create this state already up from 1000 watts output. But if you power them up and feed them with the rated capacity of 3000 or 4000 watts, they unleash elemental and mighty forces. Levels up to 151 dB with the 30 cm (box volume 70 L) and 154 dB with the 38 cm subwoofer (box volume 100 L) inside cars are no problem – assuming you want. Even at quiet levels these woofer play absolutely sovereign and smooth. Technically the VISION VE woofers convince with their sturdy die-cast aluminum baskets, triple-magnet drivers, chrome pole plates, dual Nomex spiders with sewn strands and a generous ventilation system to cool down the large 76 mm CCAW voice coils.
