DE250 and Horn combo tested here

[ttan98]

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 1.5Kz.cheap, 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.

cheers.

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.

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.
