We always jump at the chance to show off our acoustic competence while fulfilling the stringent requirements for THX certification.  The System 4 THX is a prime example of both: A home cinema system in its purest form for small to medium-sized rooms that will put you right in the action.

Why THX?

THX is the industry standard for movies and music. It guarantees a high-quality sound experience so you don't miss anything the sound engineers put in.

Loudspeakers with THX certification guarantee the following:

  • 3 identically constructed & tuned front loudspeakers for homogenous and precise sound reproduction
  • Maximum noise reduction at high volumes for a consistently clean and detailed tone
  • An almost completely linear frequency response for extremely accurate sound reproduction
  • Wide dispersion along a broad horizon that reaches more listeners
  • Distortion-free high volumes for authentic sound reproduction

An authentic cinema experience in your living room

The compact yet extremely high-performance satellites offer smoothly integrated sound reproduction for movies and all types of music. We spent several months and went through countless prototypes to determine the final position of the set’s special flat membranes as well as the shape of the enclosure, baffle, and grilles. The result is extraordinarily wide and uniform dispersion for an all-encompassing surround sound that delivers an authentic THX experience.

A slender appearance belies real power: the S4000 SW is capable of ultra low frequencies all the way down to 35 Hz. Three X 130 mm woofers manage an enormous 8 mm of excursion. This movement fully compensates for a smaller membrane surface. The subwoofer’s drivers are nothing short of sensational:  An ultra strong magnet, close tolerance, perfectly round coil carrier as well as the use of robust adhesives enable exceptional load capacities and thereby the clean rendering of low frequencies. Teufel's proprietary Air Stream Bass Technology suppresses wind noise in the bass reflux vent.

The THX dipoles ’ omnidirectional lateral dispersion greatly contributes to the realistic sound reproduction of the rear speakers. Two midrange drivers and two tweeters produce enough power to reproduce even very dynamic soundtracks with a high degree of realism. A cinematic soundstage, whereby individual surround channels are reproduced by multiple loudspeakers, is convincingly simulated by dipole speakers.

Not only does each component delivery amazingly precise sound, the components work harmoniously with each other for an enjoyable listening experience. As audiovision wrote in their review:

"Musicality and balance are the true strengths of the compact THX set from Teufel. Even long listening sessions don’t reveal any flaws that could disturb the fine impulse fidelity of the soundstage."

Lacquered side panels provide additional support and minimize cabinet resonances. The contrasting finish is subtly underscored by red synthetic inlays in the shadow gaps. In terms of set-up, the speakers can be easily wall-mounted thanks to handy keyhole brackets. The AC 4002 SP stand allows the speakers to be placed at ear height. With the AC7500 SM wall mount, the speaker can swivel in a horizontal direction.

Thanks to its efficient design, the System 4 can be connected to even inexpensive A/V receivers (THX licensed receivers are not absolutely necessary) with good results.

A big sound statement in an understated size

The System 4 offers all the advantages of THX tested and certified acoustics, but is small enough to be easily integrated into any living room interior. The ability to reproduce not only movie soundtracks but all kinds of music at the highest hifi niveau makes the System 4 an excellent and very versatile 5.1 home cinema set.
