With defined dispersion characteristics for perfect Dolby Atmos surround sound

Dolby also imposes extremely strict requirements to ensure that the demanding multi-channel procedure can generate perfect reproduction. The dispersion characteristics and position of the add-on loudspeakers are important. A subwoofer with an integrated tweeter, a so-called coaxial driver, is the best option here. The Cinema Ultra AEH 400-ATM is a coax with a 13 cm bass plus 25 mm tweeter cone and is a perfect fit, in terms of both external appearance and installation depth, on top of an LCR 100-THX – which is also where it should be according to the Dolby guidelines. For those cases where home cinema fans prefer to mount the excellent sounding AEH 400-ATM on the wall or ceiling, we have, instead of the frequency response optimised for ceiling reflection as stipulated by Dolby, included a second crossover for linear reproduction which can be activated via a toggle switch.

Test review (audiovision, 04/2016)

"Hard to think of a better all-rounder. Great!"

+ Sensational macro and micro-dynamics
+ Vivid sound stage
+ Subwoofer with good level stability and depth

Conclusion: Great dynamics, but with feeling

"With the Magnat Cinema Ultra, the developers have created a loudspeaker set that is fun in the truest sende of the word. The concept and finish are consistent and coherent, from the well thought-out details like the VESA brackets to the add-on speaker that can serve as a Dolby Atmos enabled speaker and be switched over for wall or ceiling use. The front and dipole speakers play together in an amazingly harmonious way and reproduce acoustic events consistently throughout the room and beyond. The exceptionally powerful subwoofer also enables the set to not only play in an airily detached way with good microdynamics; it can also pack a powerful punch, easily reaching cinema or live concert level even in large rooms. Hard to think of a better all-rounder. Great! "

Test result: Very good
Price/Performance: Outstanding


"Saving on looks, which don’t really count anyway, and showing off with the special effects and the balanced, differentiated fine-tuning of the sound quality. Andadded to that: micro and macro-dynamics in abundance – incredible. Incidentally, Magnat also makes music almost as crisp as a small PA."

"Our new reference among THX-compliant loudspeaker systems."

+ THX Ultra 2 Licence
+ Option Dolby Atmos speakers
+ Extremely powerful subwoofer


"Magnat has landed a very big hit with the new Cinema Ultra Set. This surround sound set plays at the very hightest level and lends wings to any movie. With huge dynamics and crystal-clear, undistorted reproduction, the Cinema Ultra Set is extremely enjoyable, can be operated in various constellations and can be supplemented for Dolby Atmos. It has also been awarded the seal of approval from the movie sound authority, THX, in the form of a THX Ultra 2 licence, so there's nothing to stand in the way of a perfect home cinema sound. Magnat Cinema Ultra - our new reference among THX-compliant loudspeaker systems."
