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!

  1. Can you please provide an estimate of the crossover component cost? This is a critical variable before committing to purchase of the design.

  2. Hi

    The DXT-MON RNX is described as "significantly less bulky than the DXT-MON-182 in terms of housing size". However, the dimensions for both are identical in the technical data. What are the correct dimensions for the DXT-MON RNX?

    The BR pipe is probably on the back, right?

    Thanks and regards
