extremely neutral frequency response: + -1,25dB of 50-23.000 Hz
Exceptional bass depth (-3dB 36Hz, -8dB 30Hz)
D´appolito arrangement => Intensive spatial representation of the sound
Both horizontally and vertically very well balanced frequency response at angles
low distortion, flawless burst-decay
optionally closed-box, bassreflex or a combination of both
=> Very adaptable, even in "complicated" rooms
Test in Klang & Ton 04 / 2013 (excerpt)
Perfectly matched equipment:High-quality woofers and the ringradiator play together as built for each other.
measurements
Klang & Ton measurement 0 °, 15 °, 30 °, 45 °
Flawless: On axis frequency response is in the range of plus minus one decibel from fifty hertz to over twenty kilohertz - the -3dBPoints are at 36 Hertz and 40 Kilohertz ...
listening
It sounds balanced, sovereign and ready to do bad things when it comes to mean levels ... profound and dynamic bass ... discoloration-free mids ... The ring radiator ... unobtrusive and extremely smooth with a profound level of detail that only gradually draws attention to itself.
Conclusion
Clever driver combination, paired with perfect tuning, results in a box that does everything right.
