Imagine my surprise that after all these years of mixing monitors that an Italian speaker manufacturer has come out with this claim on their website...
"COMPLETE ABSENCE OF FEEDBACK
The advantages of the coaxial transducers are
the complete absence of feedback and, thanks to the coherent single spherical wave front with a perfect dispersion control, a perfect listening in every position. "
I wrote an email to take them to task on, what I see as, false claims. Nothing new I guess...
Oh, and the grammar... :o
:o ::)

It's very possible to create a speaker with no possibility of feedback. Just eliminate the input connection on the speaker. Duh.
-
Or don't fit a voice coil or a magnet.
If they're so good, we should use them for everything!

If it's an active model, maybe it has built-in feedback killer?

You're kidding, right?

Yes. His name is Guido, and he pays you a little 'visit' if there is a squeal, howl or rolling rumble. He only pay one visit, however. You learn fast or find you can't mix with prosthetic hooks. ;)

LOL!!! ;D ;D

I will agree that a coaxial design has the POSSIBILITY of better gain before feedback-but not the ELIMINATION.
HOWEVER just because it is a coax does NOT mean that you can get a better response out of it.
There are two factors that have to be considered.
The First is having a good physical alignment between the woofer and HF driver. Not all drivers "allow" for a good crossover alignment.
The next is the actual crossover design. Of course if the driver is physically wrong-there is nothing you can do in the passive crossover to fix it.
I have no idea what manufacturer is in question, but there are examples all over the place of products that "think" they do something that is impossible.
But that does not stop the marketing dept. ;)

The company is question is RCF and this is in the description for the NX series of bi-amp'd powered wedges. No need to beat around the bush.... It's certainly hyperbole. In fairness, as a modern DSP processed coax wedge, in my experience it has above-par GBF feedback on the usual mics compared to popular competitors. That is what they should have said - it should be enticing enough to say that. Don't let their marketing departments flashy language turn you off from the box though :) it's a great box.

RCF.
If you highlight a section of the sentence quoted and do a Google search for it, you will find the claim on their website and the websites of others selling the product.

They’re an Italian company, so I suspect a little bit got lost in the translation to English, combined with an over enthusiastic marketing department.
I wouldn't lose any sleep over it or the gramma; it’s still a good product.

Yes it's RCF but I didn't want to be specific and look like I was just slagging the company.
I heard this box at a demo day and we have one on the way for further testing.
It does sound quite nice and I won't let marketing BS throw me off a good product.
While it's common to see the truth stretched somewhat in advertising, I had to call BS on this one and contacted the company and the Canadian distributor.
As for the grammar, I can let that slide considering the Italians make great coffee and cool cars and bikes ;D

That's fair enough. I wanted to know who ut was though! Even if RCF changed the wording on their website, it has been copied by a fair number of distributors now so it wouldn't make much difference.

Coffee - Hate the stuff
Italian cars - Rust buckets.
Italian bikes - You might have something there!

Its good that there are more coax wedges on the market now. It makes a noticeable difference for wedges

I use NX monitors and can attest that I've never had any feedback ::) .
Although I wrote that with some sarcasm, the reality is I can't actually remember ever having any feedback issues with these monitors for the dozen or so shows and festivals I've used them on. Just turn them on and they get loud without any EQ. I don't need to run them anywhere near the volume where they would feedback.
I don't do super-loud stage volumes without IEMs.
Although they tested similarly, I like something about the sound of the 12 over the 10, other than the size and weight. Those 10s are amazingly compact.
Nice compact monitors. I don't have any hands-on experience with similarly priced monitors for comparison.

The sample came in yesterday and I had a chance to listen to it.
I didn't realise the volume was full up on the amp and drove it into feedback right off the bat. DOH!
Maybe it was a defective unit ;)
Anyway, the 12 does sound very good and, yes, GBF is very good as well.
Put it up on a stand and listened to music playback. Still good.
Shot it with SMAART and it looks reasonably flat with a small dip between 3-5 K.
To me, they sound better with the bass contour button in the "floor" or cut position.
Otherwise, great overall cab. Probably going to get 6 or 8. :)
