Small but mighty: the small Nubert offers great HiFi virtues.

  2. Data sheet

The NuBox 311 may not quite deny their genes: compared to the old model 310, but crucial details have changed. Firstly the optics: A shiny acrylic front is a so edgy series like striking design, the foil surface looks quality. The proven combination of size 13 and fabric dome has remained, the membranes are but different coating than in the predecessor.

Especially the crossover vote has changed. The new 311 in the high-frequency audible neutral supposed as the old 310. Nubert uses the components not only to the distribution of sounds at different frequencies, but smoothes the frequency with complex filters. In the case of the new NuBox series are also the edge reflections in the field with three kilohertz in the calculation involved.

A feature of the more expensive Nubert series finds himself for the first time also in the entry-level model: the tweeter can be either easily lifted to switch if the acoustics should be too much attenuating this area. In the AUDIO listening room especially the neutral height adjustment had a positive effect compared to its predecessor.

Hearing test

Where the height information in Schubert’s octet (AUDIO Super listening course 5) like with an additional Spotlight illuminated the 310, the 311 could produce significantly better balance to the middle tones. That was not to the detriment of the detail view – also the new NuBox would call a high Ender probably as “high resolution”. In other disciplines she held the high level of its predecessor, without a significant drop: in too deep, at moderate volumes but extremely dry bass, who just took the kick only the spikes of drums. In comparison with the Mordaunt Short could score the NuBox 311 with more detail ability and the more neutral tones, not quite reaching the gentle ESS and the spatial presentation of MS 902i however.
