Aurum Cantus AST2560 Aero Striction Tweeter

The Aurum Cantus AST (Aero Striction Tweeter) AST2560 pneumatic transducer is accurate, efficient, and ideal for applications ranging from compact 2-way to dedicated supertweeter. A powerful neodymium motor and "bellows-like" convoluted aluminum diaphragm combine to deliver sensational high frequency output. Sound is produced by compressing and expanding the air molecules that couple with the diaphragm's radiating surface. The AST2560's audio reproduction is immediate, highly defined, and capable of tracking complex, dynamic waveforms.

Aurum Cantus AST2560 Aero Striction Tweeter
Aurum Cantus AST2560 Aero Striction Tweeter is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Excellent tweeterI can only support what has already been said. In 30 years of fooling around with speakers, I think this is the best sounding tweeter I have tried. Very natural sounding, crystal clean and and fast. Best of all it does not beam in the vertical dimension like a ribbon. Not inexpensive, but not too expensive either.

Rated 5 out of 5 by from excellent tweeter if modified correctlyThis is a great tweeter if used correctly. I am crossing over at 8k using two 2.2mf caps. I don't know why but it sounds better with two caps instead of one 4.4. Also the small screw terminals are easier to hook up with the two caps leads. I could not get much information on this tweeter online or from tech support. Nobody has heard it. I was told that it could not be used dipole. It can. I must warn that the back of the tweeter membrane is only protected with a thin felt strip. IF YOU USE THESE MONOPOLE YOU MUST MAKE A REAR CHAMBER. There are no instruction with these units. I have been working on this dipole speakers for almost 5 years and will be showing at the Rocky Mt show. so I have been building for over 30 years. Now for the brave. These heil type tweeter did not sound that great as monopole. I believe it is the thick front horn loaded face plate that produces the honking sound. Once I removed the face plate and rear felt I placed them in a piece of 3/4inch Mdf .the sound was transformed (see picture). I mortised the back side to the outside dimensions and the front to 1 1/8 X 2 1/2 inch. The tweeter unit is 5/8 inch thick so the front mdf is only 1/8 inch thick. A drop of hot glue at the four corners and set the unit in place. It looks great and better yet completes my dipole design. The smoothness and sound stage are enormous. The total lack of stored energy almost makes you think the unit is rolling off the highs. Nothing could be further from the truth. The total lack of stored energy make this perhaps the best tweeter I have heard. Yes at least as good as the scan speak beryllium or the raven ribbon which are $1000 or more a pair which were the best tweeter I know of. This has been a fascinating project for me and I have enjoyed the challenge of building a completely dipole design. My room is open floor space so the dipole is more room independent than any other design I know of. One big benefit is the back side of the dipole fills the whole house with music when not critically listening. The 7 inch driver is made by Dc gold in USA it is the reference 7R unit. I have yet to hear its equal in a dipole setup. It handles 120 hz up to 8k. They are an excellent value though not cheap. Good luck Ralph

Is the rear of the magnet open-vented on these- in other words, do they need a sub-enclosure when sharing a cabinet with a woofer/mid-woofer?

Asked by: aric audio
The back of these drivers are sealed.
Answered by: MattP

I'm running very loud professional mid-bass drivers with efficiencies from 96 db to 99 db. Will this work? Is it possible to use tweeters with lower efficiency with higher efficiency speakers?

Asked by: Shane Urbanavicius
There are a lot of factors involved with this type of question. Please contact our tech support for more help with this question, or 800-338-0531 x1.

lowest 2nd order x/o point?

I see it says can be crossed at 1900 hz, but just checking as it doesnt state what slope. Thanks
Asked by: fish fingers
That would probably be for a third order crossover if I had to guess, but what I think they are saying is that it wouldn't damage the tweeter if you put your 2nd order high pass at 1900 Hz. I would think that you would want to go a little higher than that though since its frequency response range only goes down to 1600 Hz. You want to always maintain at least one octave of seperation between the speaker and the bottom or top of its range if you can help it.

If used as a monopole, what kind of chamber would be best?

In their original speakers these sounded great, but I haven't seen the cabinet specs.
Asked by: Ed B.
These do not require a chamber in the rear since they are already sealed.

How is the vertical dispersion of these type of drivers,do they "beam" like ribbon drivers

Asked by: T sprite
No they do not beam on the vertical axis. Please read my comment on the customer reviews. These are very fast drivers and they store very little energy. What is most important is what mid-range or mid-woofer are you using to avoid a speed mismatch between drivers. If you are building a two way, I would go with the bigger units and cross over much lower, as low as 1300 hertz with a Linkwitz 2nd order crossover or use a dome tweeter. If you are doing a three way this tweeter can cross as low as 2500 hz. Remember to invert the phase on the tweeter for second order crossovers. good luck Ralph.

Can rear felt be removed for bipol/dipol applications?

Is it possible to get a pic of the rear without the rear felt?
Asked by: The Audio Artist
While it may be theoretically possible to pursue such a modification, it's not something that we can do here, unfortunately. Doing so would most likely void the manufacturer's warranty.
