Additional technical data on Beyma 15XA38Nd

Having requested a few bits of additional information from Beyma regarding the compression driver unit, they kindly responded quickly and I post this information that has been kindly provided by Beyma. They are all associated with the HF unit (or compression driver) on the 15XA38Nd. Also of note, I received a confirmation from Europe Audio regarding the shipping of the drivers, and I look forward to their arrival next week via FedEx.

DC Resistance (Re) of the HF Unit = 10.05 R

  1. Hi there! I am really interested on follwing your developments with the Beyma. A couple of them just arrived some weeks ago and have to start working with them (not much time now). I don´t have big technical knowledge, so would appreciate your comments on them.
    Thanks in advance!

  2. Thanks for that. The speakers did arrive a few weeks ago, but in the process of a house move, and haven't had a chance to open them yet. But at the moment, my thoughts are a Onken type enclosure or an Open Baffle. Or, an Onken with a removable back, so that it can become a pseudo U-shape open baffle.
