The 18NTLS5000 represents the latest 18sound technology for high quality, low distortion applications, in compact subwoofers suitable for HIFI and high power cinema usage. The longest tetracoil we ever developed (43mm deep) is pushing an high mass membrane, while an ultra long suspension system, made of a single roll rubber surround and a double silicon spider keeps everyhting in control even at the highest excursions. Thanks to the combination of the super wide Bl symmetry provided by the tetracoil technology and the state of the art suspension compartment, the 18NTLS5000 represent the perfect hybrid between high power professional drivers and HIFI oriented applications.
