It made sense to test the, allready in Mark K's ER18DXT installed and proven combination of Seas ER18RNX (H1456-08) and Seas DXT 27TBCD/GB (H1499), also in the DXT-MON series.
And the test was successful ... In terms of cabinet size, it is significantly smaller than the DXT-MON-182, correspondingly a little less deep bass. In terms of horizontal directivity, the DXT-MON-RNX sets the bar even a little higher. An extremely fascinating speaker!

Technical data

Frequency range (-3dB): ~ 36-> 20000Hz
Sensitivity (2,83V/1m): 84 dB
Crossover frequency: 1950Hz LR4
Nominal impedance: 4 Ohm
Principle: 2 ways, passive membrane
Net volume: 18l
Dimensions (HxWxD): 380x224x338mm

Applications

ambitious stereo applications in small to medium-sized rooms
passive near-field monitor
In home theater aplications as a main, center or rear speaker. With DXT-MON and DXT-Wave perfectly combinable

Features

extremely neutral and precise reproduction
outstanding uniform directional behavior
lowest harmonic and non-linear distortions
the built-in drivers are of the highest quality
very impressive and effortless reproduction of even the lowest notes
Thanks to the passive membrane (Dayton DSA-215 PR or Seas SP22R) there are no problems frequently encountered with ventilated systems in terms of flow noise or "mid-range waste"
