As a consequence, none of the ordinary catalog technical specifications will prepare you in any way to the exemplary Norton®i-Series sonic performance.

In order to deliver the best sound quality, i-Series loudspeakers are designed to be exclusively driven by Norton® ND2 or CF10 power amplifiers that integrates all the required signal processing and firmware.

The i118b is a very accurate low distortion and high output   bass subwoofer that delivers consistent performance down to 35Hz in a very compact enclosure. The i118b contains a single high power and long excurtion18" LF transducer integrated into an optimally tuned bass-reflex enclosure and is intended to reproduce the lowest frequencies reliably, consistently and with great fidelity. The i118b could be used stand-alone or in bass-arrays with controlled directivity. Combined with i12 the i118b forms a multi-way system that delivers an amazing combination of fidelity, depth and impact.
