Categories: Monacor Tweeters Ribbon Tweeters
Air motion transformers (AMT) are a unique type of high-end ribbon tweeter which were developed by German physicist Oskar Heil during his research into the characteristics of the human ear.
Although AMTs are members of the ribbon family, they have a radically different mode of operation: these tweeters feature a specially folded / pleated diaphragm that expands and contracts along its length like a bellows transforming an electrical signal into air waves and can therefore technically be viewed as a type of sound modulated air pump.The folding of the AMT diaphragm offers a larger active radiating area in the minimum of space.
AMT tweeters have a highly dynamic sound with an excellent transient response, very high efficiency and low harmonic distortion.
We recommend a minimum crossover frequency of 3kHz / 18db octave.
Frequency range | 3kHz-30kHz | Nominal impedance (Zn) | 8 Ω |
Ribbon dimensions | - | DC resistance (Ribbon) | 5.2 Ω |
Effective area (squared) | - | RMS power handling | 60 W |
Crossover frequency | 3kHz 18db | Peak power | 120W |
Sensitivity (2.83V/1m) | 98dB | Faceplate | 130x90mm |

Since 1991, I've had Linn Keilidh speakers, which I upgraded a year later to an active system using the Linn Wakonda and two LK100 power amplifiers. Over the past few years, I’ve considered replacing my audio setup with a more compact active system. However, the downside is that it would require a significant investment to achieve a comparable sound quality.
In the end, I opted for an upgrade of the tweeters and new speaker covers after more than 30 years.
The upgrade itself went smoothly using the supplied solder. I’m very pleased with the end result. The upgrade has had a noticeable impact on the soundstage: the bass, midrange and treble all have more space and clarity within the stereo image. This first became apparent to me when listening to vocals—it’s as if you can perceive the space surrounding the voice. And the longer you listen, the more this spatial detail stands out.
I’ve turned the amplifier up slightly, as creating that sense of space seems to require a bit more power.
It’s an upgrade I can definitely recommend.
Wow, just had my Mission 753 upgrades of crossover and also tweeters. What a difference it’s made! The high frequencies are more refined and OMG, the separation and richness of mud and bass if awesome…..much thanks to Willy’s for giving my 753’s a new life 😀😀
Excellent advice from will as usual and exactly what I wanted. These have improved the sound of my current speakers and taken them to another level. Sounds superb I can hear tonal difference's between things that I never heard before. Superb bass drivers dig so deep.
As usual will has been outstanding.
Brilliant to deal with always helpful and gives great service.
What a brilliant capacitor, from first listen exceptional clarity and depth. Bargain will be buying more.
Swapped out the 30 yr old AlCap capacitors for the Audyn Q4 on Wills recommendation (along with a ferrofluid change). What a difference, added so much more definition and clarity. Very impressed. Audyns are a fair bit bigger size wise but fitted easily enough on the board and the access aperture on the TDL Studio 1's.
