The No. 3.1 loudspeaker is a perfect introduction to the fascinating sound world offered by a plasma tweeter. The goal of this design was to create a benchmark two-way loudspeaker with compact dimensions and an elegant appearance that is easy to integrate into any living or listening space. The main challenge was to develop a driver for the midrange and bass frequencies that is seamlessly matched to the superior speed and resolution of the plasma tweeter. This 20-cm driver design combines a very fast midrange response with a beautifully low bottom end and is complemented by a 22cm long excursion, which is integrated in a down-firing arrangement

The enclosure is based on a combination of MDF, low-vibration ceramics, and absorbent heavy foam. On the interior, a reinforcement matrix provides interlocking boards to further increase the enclosure’s rigidity. The base plate is a one-centimeter-thick aluminum slab that also holds the floor spikes. The loudspeaker cabinet is thus completely decoupled from the floor. The angled inclination of the narrow baffle is an effective solution for time-correcting the impulse responses from the two transducer systems. The loudspeaker’s phase position is perfect at a seated listening height. The No. 3.1 model thus satisfies both your needs for exquisite sound quality and for appealing, subtle visual aesthetics.2016-06-13_11h16_49
