Rated 5 out of 5 by from Stand alone super tweeterUsing as a stand alone super tweeter crossed at 8500 hz with 3rd order crossover and L pad. Plays loud but very clean and fast with little distortion - adds top end shimmer to Tannoys

Rated 5 out of 5 by from Excellent TweeterVery good quality tweeter. Easy to fix if you blow it out. These are used in very high quality Salk speakers. Recommend to give the best shimmer at the top. Be sure to cross it right.

Rated 5 out of 5 by from When this tweeter goes on sale, what a value!!!!!I have used these Aurum Cantus G2s in three speaker projects now. They are extremely well made and have the air, dynamics, and frequency extension that I love in a tweeter. I have seen several speakers made from OEM venders and it looks like they use the same or very similar tweeter in their speakers. One high end manufacturer uses this similar tweeter in his speakers and they sell for $30,000 or more!For do it yourself hobbyists, this tweeter is high on the curve.

Rated 5 out of 5 by from Not too bad for that priceQuite pleasant to listen to. Good choice in this price range. Good sound with tube amps.

Rated 4 out of 5 by from Good ProductDhese Tweeters are very naturally and transparent sounding.I love them more than all dome tweeters i heard bevore.Overall built quality is good for a Chinese product.But take attention for too much power (6dB Crossovers),because the ribbons stretched under to much stress.Ok,you can change the ribbons,but that is a very difficult work to do.These units are really not for PA Speakers,but they are very good for audiophile stuff.

Rated 4 out of 5 by from Excellent Tranparecy and Horizontal DispersionI used this tweeter in an MTM cabinet with two Aurum Cantus, 5-1/4" carbon, kevlar woofers and a 3d order x-over at 3kHz. After toning down the slight bump in the frequency response at 10kHz with an LCR notch filter I was able to achieve a +/-1dB flat repsonse from 3kHz up to and past 20kHz. The transparency and detail of this tweeter is excellent and the sound is never harsh or too bright. The frequency response falls off rapidly in the vertical plane outside of 20 degrees or so but only in the upper octave. I don't currently have any high quality tweeeters to compare these to but cymbals and other percusion instruments never sounded so clear, crisp and natural.

Aurum Cantus G2 Ribbon Tweeter

What is the lowest recommended crossover frequency for this tweeter? Can you recommend an ideal filter slop if I were to couple the G2 to a pair of Aurum Cantus AC120/50CK 5" Midwoofers wired in parallel? Thank you!

Asked by: Pontifex
Aurum Cantus recommends a minimum crossover of 2,500 Hz, although there is no mention of slope. I would safely say a minimum of second order.

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

I see the G2 is available in a rectangular housing. Is it also available in a round housing? Similar to the G2Si.
Asked by: JCris

Watt level

My amp puts out 110 amps @ 8 ohms, is that too much power for this tweeter?
Asked by: Vintage Listner
Assuming that you meant 110 watts rather than amps, it could be too much power if you were using that amplifier exclusively for the tweeter. However, in a 2- or 3-way speaker system, the woofer will use the vast majority of the available power, leaving relatively much less power available for the tweeter. That being the case, I'd say this tweeter would be perfectly fine in a 2-way or 3-way system powered by your 110 watt amplifier.
