QEUS APS SERIES

The QEUS APS SERIES is a speaker system of unprecedented compactness that fits perfectly into any room.

The problem solver
"The QEUS APS Series loudspeakers are the unique solution for almost all sound applications, elegantly discreet, powerfully superior in performance."



The APS Series
A speaker series that sets standards

The innovative QEUS APS Series, a combination of flat diaphragm and magnetostatic drive, is a speaker system of unprecedented compactness that blends harmoniously into any room design. The speakers are available in four lengths (APS50: 50cm, APS70: 70cm, APS100: 100cm and APS120: 120cm) and in 2 colours (white and black), for every conceivable application.

The APS loudspeakers are not equipped with conventional dynamic drivers, but with 20 x 120mm flat sound emitters. The APS50 has two of them, the APS70 and APS100 three and the APS120 four.

These are not, as usual, driven by diaphragms in the centre, but, similar to a magnetostat, over the entire surface. The result: a large, homogeneous and evenly vibrating surface that concentrates the sound vertically, but not horizontally.






The QEUS APS Series can focus on the frequency spectrum above 170Hz (APS50/APS70 above 160Hz, APS100 above 150Hz and APS120 above 120Hz) with a phase correction previously uncommon in this price range. The APS drivers focus sound energy and, combined with redefined speech and music intelligibility, achieve unprecedented range. Whether you use a digital, analogue or tube amplifier as your sound source: The APS behaves similarly to a real resistor.


The design of the APS avoids the usual high, complex loads found in all conventional passive loudspeakers.

These new technical features of the APS Series allow to use the speakers in a variety of ways: From an unobtrusive centre speaker, the use as an additional pair in existing systems, to stand-alone use in complex multi-channel surround systems. In addition, the APS Series is also available as a 2.1 complete system with subwoofer and specially developed crossover.

The latest technology in all components

The QEUS APS Series speakers deliver an unprecedented sound experience. The horizontal dispersion angle is 160° and the vertical dispersion angle is 40°, which makes the loudspeaker almost unlocatable to the human ear. With the QEUS APS Series the sweet spot grows to unprecedented size.

The QEUS APS Series enables a unique ambient sound. In contrast to conventional technology, the sound level varies significantly less. While conventional systems have a sound drop of 6db per doubled distance, with the QEUS APS Series it is only half of that with 3db.






Revolutionary technology

The chassis of the QEUS APS Series are as new as they are unique in their design: they feature a high-quality and unique honeycomb membrane system, built into an extremely compact body.


Intelligent drive

The conventional voice coil is replaced by a multi-layer PCB that drives the entire surface evenly thanks to two neodymium magnets.




Technical Measurements

APS Series technical meqasurements that speak for themselves.










Uncompromisingly slim design

At just 36 mm wide and 22 mm deep, and only 510 mm (APS50), 710 mm (APS70), 1010 mm (APS100) or 1210 mm (APS120) long, the QEUS APS Series speakers blend elegantly and unobtrusively into any room.


Unlimited applications

Thanks to their extremely compact design and unique performance, the speakers can be harmoniously integrated into any room design: classic TV/amplifier arrangement in the living room, home cinema rooms, integration into a complete house sound system, use in conservatories, horizontal or vertical mounting - let your ideas run wild.

Hard to see - powerful to hear

Play Experience

“With the APS Series, QEUS brings us a loudspeaker that can be wonderfully integrated into any room and, despite its discreet appearance, provides an outstanding and powerful sound image. Whether used purely as a stereo system with the ELEC subwoofer or as an addition to a home cinema, the APS series is barely visible but can be heard powerfully...”

Model variants

The QEUS APS Series speakers are available in four different lengths (50cm, 70cm, 100cm and 120cm) to suit almost any application. Each version can be purchased as a single speaker for use as a centre in a multi-channel installation, or as a pair.


In addition, we offer a perfectly matched 2.1 complete solution of all four lengths: The loudspeakers are then combined with the Elac SUB3010E subwoofer, which perfectly matches the characteristics of the QEUS APS Series, as well as a crossover specifically developed by QEUS for optimal combination with the subwoofer on into one installation package.
