"The Heart"
The 666 and 666DB compression driver
The Compression Driver – The Heart of Unparalleled Sound
In a horn system, two key elements define the sonic character, and one of them is the compression driver. This is where the difference between “pretty good” and “absolutely breathtaking” is made.
With the Model 666, we set out to achieve the extraordinary: a driver that not only impresses but redefines expectations. High efficiency, ultra-low distortion, an exceptionally linear frequency response, and an incredibly powerful motor – we’ve achieved it all with this masterpiece.
Technical Excellence That Speaks Volumes
The performance of the Model 666 is unmatched:
• K2 (second harmonic): At -40 dB below magnitude, it is imperceptible to the human ear, which can detect distortion up to about -35 dB.
• K3 (third harmonic): With an astonishing average of -70 dB, this driver sets a new benchmark for precision.
The secret behind this exceptional performance lies in its motor. With a field strength of 23,500 Gauss, it is the most powerful and, thanks to its extremely lightweight diaphragm, also the fastest driver in its class. The diaphragm excursion is less than 0.1 mm, even at high room volume levels. This enables an unparalleled reproduction of even the finest details, which would otherwise typically remain hidden.
A Sonic Experience Like No Other
The dynamics, detail resolution, and transient response of the Model 666 are nothing short of extraordinary. It brings your music to life with breathtaking realism, revealing even the subtlest nuances that make every performance feel intimate and alive.
The Model 666 – The Holy Grail of Compression Drivers.
