New Celestion Full Range Compression Driver Axi2050

So I just bought a new Celestion Woofer and noticed this on the Celestion website when I was snooping around:

This beast looks like it will do 300hz to 20khz....good lord!


http://celestion.com/product/174/axi2050/

and a youtube video talking about it:


Sounds like something to go toe to toe with the BMS COAX....at any rate looks really impressive! Anyone know anything about this?

This is an amazing compression driver design. I wonder how much it will cost? I also wonder who, if anyone is producing horns or waveguides that will accommodate a 6" compression driver, and can hold pattern from 300hz all the way to 20,000hz?

I've been waiting for my sample for a little while. I believe they will be a bit less than the BMS coaxials.

Finally a worthy CD. I want to hear this. Hope it sounds good.

Thanks for posting, I haven't been around the Celestion site in a while.

While I was looking around, I saw someone mention a $395 msrp. I'll try to find the reference and post the link... Not sure how accurate that is, but if so, very attractive

Sent from my F3113 using Tapatalk

Hmmm....can't find that reference, maybe I was imagining that, but did see someone mention it is half the price of the BMS coaxial here:

http://forum.speakerplans.com/celest...opic96040.html

At any rate more competition is good. It would definetly be cool if someone got a hold of one of these puppies and tested them.

Looking at it's response on an actual horn (not plane wave tube) the extension looks only a little bit better than some of the best 2" large format horns already out.

I could see how this would look awesome but I'm not too convinced it's anything special just yet.

And that's probably going to be the only great thing about this. A good value.

Depends what you want it for, this + nice midbass horn = win (maybe) in a 2 way. Now if you want a nice flat measurement, move along

That might be all that's needed, but who knows.

They did send me some preproduction 1" compression drivers either late 2015 or early 2016 that had hand written 'engineering samples' and build numbers on them. They weren't bad, but didn't extend quite as high as I was hoping. There was a very interesting sample that they decided not to produce because they didn't think demand would be high enough. The guy I was dealing with talked to corporate and at first they were going to make them just for us, but the order had to be at least 1000pcs. It was a lot of money but I really considered it, after a couple weeks they changed their mind.

Did you think I thought this was a super tweeter?

The point of these is to use it over the widest range of frequencies possible. I don't see how this does that any better than what is already on the market.

Do I have to break out all the pdf's of every 2" output horn on the market? Well I'm not.

You don't have to tell me why a wide-range driver like this on an awesome 2-way system is awesome. I need to know why this driver is better than what I can get already.

No I did not.

Yes wide frequencies but it is gonna be down at the top, I don't dig out all the CD specs but the larger ones roll off more or are coaxes, dunno about this one since I haven't heard it but it looked good to me for a 2 way, that is all. Also Celestion is often nice sounding IMO so I think it has potential based on the little info there is, but potential is the key word. I gather this isn't a coax.

It's appears to be "full range" and not coaxial.

IDK. I just see another titanium diaphragm large format compression driver here.

It's got a 5" voicecoil though so...I'll give it that.

Lol, how many CDs, not coaxes, thats good for 300-20Khz? I have been out of the CD game a while, please enlighten me. Yes some roll off is fine.

300 might be a stretch for this but seems better than most CDs I remember. If you have a CD in mind that can go lower, I am all ears.

How bout one that is flat to 20khz while also flat to 300hz? Don't forget that part.


You find one, you let me know.

what I don't like is the "OEM only" comment although maybe Eric can work around that for us

I'm much more concerned about it going lower, roll off into the top is fine by me. Like I said the first time, it's not going to be flat.

Check out the BMS midranges then.

They are good up til the 6-8khz range and then roll off. All rated down to 300hz like this one.

Interesting design. If I ever build a bigger theater in the future I'll have to look into this more closely (maybe...)

It's an annular diaphragm, so for breakup the relevant dimension is not the 6" dia, but the distance between the annulus ID and OD, which looks to be about 1 1/2".

And it's effectively less than that because the VC is not at one of the edges.

But if this isn't the first annular diaphragm with this size/range, I guess it's not the big deal the guy in the video makes it out to be.

I don't think it's gonna be enough, but I assume measurements will eventually be published. Will be interested to see.
