| 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! |

Crossover
Can you please provide an estimate of the crossover component cost? This is a critical variable before committing to purchase of the design.
Hello Tom
With Jantzen standard parts (3 Aircoils, 1 Iron-Core Coil, 6 Crosscap MKPs, 6 Mox 10w resistors) about 65€ in Germany.
Sorry for the delayed answer!
Best regards
Alexander
Can you provide an impedance plot for the DXT-MON-RNX? Or at least a minimum impedance @ approx. frequency?
…done… 🙂
