DE250 and Horn combo tested here
I have tested a no of horns with the B&C DE250 compression driver. Those I have tested are:

1. B&C ME10, norminal x-over at 2.5Khz, and cannot use below 1.7Khz, recommended above 2Khz.

2. PE, 10" circular horn, min x-over at, not recommended.

3. RCF, H100 x-over as low as 1.5Khz. recommended

the last one, RCF H100 is by far the best, at $28 each at Loudspeaker plus. sounds good without equalizer required, fluctuate +/- 8db between 1kHz and 18Khz.

The combo costs about $130, a good deal and sounds very good, open and dynamic and smooth.

Some DE250 and a lot of DE25 measurements with various horns are available here. But RCF H100 is missing. Could you post or PM it? Thank you.

Take screenshots. Hit Prtscn, then open Paint, hit Ctrl V, then modify and save.

I cannot get my prtscn to work?

Anyway how is your testing of DE250 with DDS Eng 90 waveguide? Any results yet. Can you post them here? I believe the combo should give excellent. DDS costs about $99 retail.

No testing yet. Probably won't be for a couple months. I'd like to use Dr. Geddes waveguides so it may wait until then. The project these are for also need a woofer, so I have an AE IB15 coming and I'm still deciding if I should also pick up the B&C 15NW76.

As for the printscreen not working what exactly isn't working about it? I don't think you should need to turn anything on on the keyboard like function lock, etc.
