thank you. This is what I was assuming. I can always add a smaller supertweeter if I need HF extension. Or just make a shelf filter when I pad down the HF driver to match the level of the 15".
I would second the Radian or Eminence Textreme N314 products. The best CDs I've heard have been Radians, and I hear a lot of praise around the N314.
Not a bad driver but sounded a little dull compared to the Radian 745. The Radian sounds good but doesn't have the resolution of the ND3SN. All drivers eq'd as similar as possible.
Depends on your hearing whether the top octave matters that much to you.
I can't be of much help here as I've never used compression drivers, but the FaitalPro HF146 has been tested in conjunction with the 18Sound XT1464 horn by an indipendent Italian loudspeaker shop with notable results.
Way out of date, but curious how Altec's once best of the bunch large format (1.4") 288-8G on a 300 Hz expo horn fares with these newer ones.
Just looking to see on cost on availability of the 18sound ND3SN in the US? Also the Radian seems like it drops off like a rock at the HF. I was planning on doing a shelf filter on the HF146 to get a bit of the top end sparkle back.
I've been getting drivers from France at cheaper prices than domestic sources....even with shipping. But it doesn't look like the 18 Sound is available until March and it's expensive elsewhere.
Honestly, most drivers of a given size and quality will get the job done. The differences after eq may or may not matter based on your ocd levels.
Anyone have any experience with the other Beyma 1.4" line? CD14ND, SMC-65ND, CD1114Fe, CD1014Nd and of course the CP-755Nd which looks promising.
Survey? Probably doomed from the start owing beryllium's high cost, but any love for the overall sound of these diaphragms?
Specifically, the Radian 745neoBe?

Can't talk to the Radian 745neoBe unfortunately, but I do have a pair of TAD TD-4001 with OEM BE diaphragms running on the previously mentioned A-290 clones. The level of detail with the TADs / Be diaphragms is on another level from the 2440/2441 or Radian 950neo. I had a lot of problems getting the Radian to integrate properly with those horns. (Lots written elsewhere) Suffice it to say there are a limited number of drivers that work well with the A-290.
Aluminum seems a lot more forgiving generally than Be. It is important that the driver exit angle matches the horn entry angle requirements.

Beyma CP755Ti is a ferrite versión. Has same diaphragm and is cheaper than 755Nd

Have you actually done some comparative listening tests with AL and Be diaphragms with you great and not great quality recordings? If yes, please share any details.
Regarding driver exit and horn entry geometries, are you saying this is largely or wholly dependent on the driver throat adapter?
I ended up going with the SB Audience 65-CDNT . For price can't really fault it. Its no TAD but again $$.
Indirect comparison of 2440 with 2441 OEM Al diaphragms, Radian Neo 950PB Al, and TAD-4001 with OEM Be diaphragms is as close as I got. In measurements the 4001 is more extended in the HF, but at least on the A290 clones this wasn't a benefit I could use because even with DSP it was harsh. The "2441" actually sounded pretty good, but distortion was much higher (both measured and in listening.) Do a search for a couple of threads where this is discussed. (I would provide links but I am a bit short on time.)
I think 1.4" drivers with the appropriate adaptor are a good way to go if you are using an older horn design like the A-290 which was designed for drivers with narrow exit angles. (say 8° - 12° ?)
DSP can't fix something that is fundamentally broken due to bad choices.
Note that I consider myself to be relatively inexperienced and am still figuring things out. I'm no expert, just have had some relatively bad experiences with 2 inch drivers. 😀

May I ask what horn you're using with it? Which tube and/or solid state amp (s)?
And on scale of 1 to 10, with 10 being the least forgiving of your less than pristine recordings, how would you rate that driver/horn combination?
Did you find this driver's overall tonality in any way reminding you or other drivers, even non-compression cone drivers?
Do you have this driver/horn on your short or long wall?

Yes - these behave very well in the top octave! I would not go down to 800Hz in a PA environment but for HiFi it's worth a look.
