I just read this. Very good value indeed

Do you think the mounting would take B&C DE250?

- Yes I think so, the bolt holes seam to match perfect. At least the pair of holes that are on the bigger radious. They are on the same diameter, 76 mm.

Looks right to me, compression driver on a horn that doesn't narrow the dispersion much as the frequency increases. But I would have like to see the driver/horn make it down flat to below 2khz.

Faital STH100 with FE104:

Click the image to open in full size.

Measured indoors in a relatively small room 2.4*4 m. Driver 1 m above floor. Mic 1 m in front of the horn.

I have used the microphone described at gainphiles blogg.

I think the response is very similar to yours jogi59 but with less amplitude. I am a very new at measuring stuff so I might have don all the errors there is but I have at least caught something with my DIY-microphone. Grate fun and thanks gainphile for the description on your blogg.

kind regards

to me, you are lifted a bit in upper mids (+5db 2-3.5khz).
That can sound harsh over time.
I'd want more high end boost.

Thanks for posting (again )! Were the measurement conditions identical to your previous measurements?

BTW, I think the most useful way of doing these measurements is non-normalized and with some global EQ in place to make the response more or less flat. Now the on-axis response is a big factor in the representation of the combinations' performance.

Below you'll find my results. Yeah alright, I'll admit: it's a normalized plot. Anyway, it looks a lot better than yours. My measurements were taken outside, gated and at a distance of somewhere close to 2 meters. Smoothing is 1/12 oct. There's a small on-axis dip at 3.65 khz, hence the apparent widening.
