That's what came to my mind. Maybe this delrin-like material has better damping in the highs than aluminium. I always look at phase plugs, grilles (or whatever people put in front of the diaphragm) with suspicion and a bottle of butyl rubber in my hand.
Love the video and feedback, I have as well been very interested in this compression driver, Is it possible to have a 10 ten C/D list , that you have test, In your opinion,
The 65CDN-T is a better overall driver offering better dynamics,lower distortion, and a flatter response. But the Eminemce excels slightly on upper treble soundstage depth/low level detail retrieval. Both drivers could stand to be a little smoother sounding however, such as the smoothness achieved with horn loaded planar.
Thanks for this review. My impressions were very similar. Great driver but it suffers at the top and has similar smearing to a silk dome tweeter. Switching to the Radian Be both lowered distortion and cleaned up the top of the response. It's a great driver but not an "end game" driver
2007 is not a horn cause it does not change an acoustic impedance. It's just a beam former. Secondly, Seas cannot play below 2k. Third, sensitivities are not even comparable. Cheers ) Good review by the way PS 700-1kHz resonance is caused by an aluminum cassis of the driver, and must be not observable being properly attached
@@JosephCrowesDIYSpeakerBuilding That's true, but then a pressure immediately drops at a throat, however I suppose that it must drop slightly as a horn expands.

@josephCrowesDIYSpeakerBuilding How's this sound compared to other 1.4" drivers like the SB Audience Rosso-65CDN-T?
The 65CDN-T is a better overall driver offering better dynamics,lower distortion, and a flatter response. But the Eminemce excels slightly on upper treble soundstage depth/low level detail retrieval. Both drivers could stand to be a little smoother sounding however, such as the smoothness achieved with horn loaded planar.
Does Eminence make a 1” exit version of this with a Textreme fram?
Not that I know of.
Hello,
if you could pick a 1,4" or 2" compression driver, money aside. What would come to mind in that scenario? :) Kind Regards
Thanks for this review. My impressions were very similar. Great driver but it suffers at the top and has similar smearing to a silk dome tweeter. Switching to the Radian Be both lowered distortion and cleaned up the top of the response. It's a great driver but not an "end game" driver
Did you flatten its response when comparing? It’s quite shelf above 10kHz.
@@JosephCrowesDIYSpeakerBuilding yes, flattened and tested in a number of different horns
@@gerhardwestphalen well, I’m glad others are hearing the same thing as me. Thx. 👍
Thanks for this. Now I know to save my money and move on to another compression driver.

Compression occurs in the phase plug of the driver.

Human ear can hear comfortably up to 15 kHz 😅
The Faital HF1460 doesn't suffer from the concerning build quality of the Eminence. Unfortunitly, the Faital is harder to obtain in North America.
Yes, I know. I’ve tried to get it.
