| 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… 🙂
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
Erich
Hello Eric
The RNX has a depth of 288mm, the DXT-MON-182 338mm. This is also stated in the technical data.
Yes, the BR pipe goes to the back.

Hello Mr. Heißmann
I'm a little confused by the possible uses.
I need a speaker that can fill my 24 square meter room with sound.
listening distance approx. 2,5-3m
You write that it is also a near-field monitor.
Possibly recording studio on the mixing console with listening distance of 50cm.
How does that work?
I hope you can allay my concerns or enlighten me.
I would like to build the speaker...
Greetings Frank
Hi Frank
Near field goes up to ~1,5m and that's what the DXT-MON-RNX can do!
I wouldn't go much below that. Larger distances are no problem at all.
In summary: Ab The speakers work perfectly at a listening distance of 1,5m!
Regards
