Aurum Cantus G1 Ribbon Tweeter
Aurum Cantus G1 Ribbon Tweeter is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Louder is betterI Love Loud Concert Level Sound. This ribbon can accomplish the task. I have replaced the voice coil on my seas millenium tweeter a sinful amount of times at 45 bucks a pop. This tweeter costs 14 bucks to repair and is 10db more efficient than the seas. Very sweet sounding in the human voice or string department. Expensive but a robust sweet sounding unit.

Rated 5 out of 5 by from Pushed and abused.Gradually tore the G1 ribbons to shreds with a Marantz SR7500. At full volume and a generic radio shack crossover.The remedy? Lindt cocoa dark brand chocolate foil wrapper and a gear to crease the strips, at forty some dollars I may fix the crossover problem first.On the negative side I did find one of the end plate screws sheared off.On the positive side,an amazing sound even with the makeshift foil,a literally indestructible speaker.

Rated 5 out of 5 by from Fast and articulateI have these tweeter ribbons mated in an mtm using two Focal Audiom 6wm midranges. Crossing at 1600 w/24db crossover makes this combo very fast and clean - you are there sound. Very efficient and not shy of very high SPLs.

Rated 5 out of 5 by from High end that's affordable!!!!!!!!!!I did'nt know what to expect when I first hooked up my G1 ribbons........ but that soon turned into amazement. Smooth.......transparent......realistic....... clear sound at it's best. I can't wait to complete my latest speaker project!

Face-up mounting?

Any problem with this tweeter be mounted horizontally - i.e. facing up, rather than having the ribbon "hanging" vertically?

GRAVITY HAS SO LITTLE PULL ON THIS.. THE MOUNTING IS NOT CRITICAL

Can this be considered a high end product?

Asked by: mrspis
Hello, may I ask why you keep asking this question on multiple items? Also, for us to tell you if it is "high end" we need to know what your definition of "high end" is. Realistically only you can make the determination since "high end" is a subbjective term.

What tweeter is better, this or AST30130? I cant decide what to buy, i want apsolutly the best tweeter!

Asked by: mrspis
Your amplifier and crossover choices will have the greatest impact on the final decision as to which tweeter is better for you. The G1 is an 8ohm driver which would require different value caps/coils than this 5ohm driver. Those caps/coils are what affect phase, inductance etc, which affect the audible experience. The G1 is way more sensitive as well; 3dB more sensitive. That plays a role in what driver it mates well with and/or how many items are between it and the amplifier, just to bring it down to match a less sensitive mid. You'll have to do a little homework on this one to figure out which one matches your mids and amp better with the least amount of caps/coils/resistors.

Correct spacing between this and Morel's SCM634 Supreme midrange.

I'm thinking of building a 2-way speaker. I have read about the importance of center to center spacing between drivers and how it relates to crossover frequency. Is that as important for ribbon tweeters and if so where on the ribbon tweeter do you measure from.Thanks
Asked by: Wookus
Excellent question. There is interaction between cone woofers and dome tweeters. There is less with ribbons due to the dispersion field. This considers a vertical design. If you do an MTM it's a more complicated crossover ballgame.Build out your cabinet and the spacing you need between the two drivers will be more than enough. With the Morel you'll be matching very well. I suggest a sealed enclosure with a total Qts of .707, or .5 if you can live with the low end rolloff - that will match the ribbon better. With this high end application - and it's more complicated - but a 24db/oct crossover will be more linear and protect the ribbon better...

What's a good woofer to go along with the g1?

I was thinking of the Eminence Delta-10A 10" (2 of them in a WTW format) with the Eminence PXB2:3K5 2-Way Speaker Crossover Board 3,500 Hz (assembled). Or if you have better suggestion?
Asked by: limechile22
This ribbon tweeter deserves a support system that provides clear responsive sound. I think you are on the right track. Several great combinations are available thru PE. If I could afford to build the system, I would communicate with tech supports best speaker builder, the get to preview a lot of speakers.

Whats the best crossover for the Amazing Aurum Cantus G1?

Would like to know values of caps and coils for 6dB, 12dB, etc., in the frequency range that this tweeter works the best? Does a 12dB protect the tweeter more? With your reply I will be able to buy the proper parts from my favorite store, PE!
Asked by: rlelectromechanical
For the recommended crossover frequency of 2kHz, I would recommend a 12dB filter. This would comprise a 6.8uF capacitor in series, and a 0.90mH inductor in parallel with the G1.
