It certainly is. I'm familiar with several applications, in RCF PA cabs and have listened to 3 pairs of Blumenhofers with the ND850 >
it's his preferred mid-size compression driver. However, these were all 1.4" versions, which also seems to measure slightly better.

Do you also have experience with those coaxial compression drivers?
But the DCX354 is too new to find listening impression...
The distortion measured in voice coil shows slightly lower distortion on DCX464?
The DCX464 has been used in many project in this form with very good result.

Did they cross over 8kHz with another driver to avoid the resonance shown in CSD?
Or it's actually not that audible
Faital HF140 will work to 500 at lower power. They give power ratings to 650. https://faitalpro.com/en/products/HF_Drivers/product_details/index.php?id=502020150
No, strictly 2 way...
The Blumenhofers are among the best speakers I've listened to, regardless of price.
The 2x220s were head and shoulders above the rest at the latest local high-end show. Still not perfect due to pattern flip and the 'handover' between the waveformer and radial horn, but in terms of imaging and naturalness from a different, more advanced universe, compared to the Magicos for example. The only system that succeeded with flying colors in 'teleporting' the listener to the band and vice versa.

Hi guys,
I just tested several Elliptical OS horn, I have never use them before:
Here are what I found vs biradial horn that i normally use:
1. Ellliptical has much smoother freq response but earlier roll off and steeper slope in the high. Need more eq to fix
2. Biradial has jagged freq response, not as smooth, but the roll off is latter and less steep than elliptical. Less eq to fix.
Can someone tell why this happens?
Any horn design that have both characteristics? \
Thanks

OS=CD so it exhibits the usual roll-off past ca. 8 Khz.
The horn path + mouth termination of most biradial horns are less smooth, which results in a (more) ragged response.
In addition, the horn is more efficient in the highest octaves due to a gradual expansion of the wavefront.
Never had DCM50s, but have listened to a system featuring the driver.
I liked it, but it's not perfect.

I guess you might be interested in this also.
DCM414 is basically the DCX464's MF part so I think it can correlate.

I have the same experience with them. Now I'm wondering why they do not sound like they are significantly lacking HF... last time I checked, I hear well up to around 15-16khz so why am I not missing anything when listening to speakers that roll off after 8khz? Is response above 10k overrated? Or is it just me?
Not worrying about HF too much makes choosing a CD for my 2-way design plans much easier...
i think it is even a better mid as there is not the same bump in the 5K region seems more flat too

The horn sections of BH speakers are (passively) corrected, so there's hardly any drop in the top octave. 2 examples:
what is the adavantages or cons between mid ring compression and traditional dome compresion drivers for mid ?
Good question. Tbh I prefer traditional dome comp. drivers, just like I prefer traditional dome tweeters to annular tweets > which were hyped about 15 years ago.
@Ro808 are those measurements of Blumenhofer speakers? If so, what model?
And if they are corrected, is still "breakup territory" is that not an issue?
In other words, when using DSP, is there any reason to not use a large format CD? Would the highs of a 1" still be better then those of a 2", or would you not be able to tell the difference once EQ'ed ?
@juanitox Also interesting question
