The System 4 is the ideal choice for home cinema or home concert fans who want an extremely compact design but no lack of sound quality in smaller rooms.

Absolute sound performance
The System 4 delivers incredibly powerful performance that sets new standards in its class.

Concert or cinema versions
The two additional speaker units (concert version) or the Dipoles (cinema version) are used to deliver sound to the rear zone.

Incredibly compact

The System 4 by Teufel is essentially a condensed version of the legendary System 5 THX Select. The design of the System 4 is the same as the System 5 THX Select save for its smaller size, use of different chassis and lower maximum volume. The System 4 is thus the ideal choice for home cinema fans who want an extremely compact design but do not want to sacrifice any sound quality in rooms up to 35 sqm.

The System 4 delivers incredibly powerful performance that is setting new standards in its class. The reason for its high performance can be found in the three identical M 450 FCR front speakers whose neodym chassis in THX compatible D'Appollito configuration ensures consistent high sound resolution. All with the smallest dimensions: The front side of an M 450 FCR is not much larger than a DIN A5 sheet of paper!

Included components

  • Satellite Speaker M 450 FCR
  • Subwoofer M 4500 SW


Subwoofer M 4500 SW
Subwoofer M 4500 SW
The M 4500 SW active subwoofer has low space requirements due to its upright design and small footprint. It features the latest power block model, extremely powerful RMS rating of 350 W and the most advanced neodymium magnets currently available anywhere in the world.

Measurements of this subwoofer confirm its breathtaking dynamics and extraordinary power, qualities that one might not expect based on external appearances. This subwoofer seems to pull sub-bass out of the basement. Whenever you want, you can recreate the sound of a pride of wild lions roaring through your living room in quite an authentic fashion. Provided your neighbours play along.

Satellite Speaker M 450 FCR
The extremely compact M 450 FCR satellite speakers are perfectly suited for all of the channels in a home cinema: Front, centre or rear – these solid, miniature speakers are perfect for each of these roles.

The D’Apollito configuration has been ‘borrowed’ from the THX standard and provides a wide listening range with extremely fine detailing. This is very important for ensuring the intelligibility of speech!

System 4 "Stereo 2.1" review of HiFi Test
"Unbeatable home theatre sound from such compact speakers – test winner!"
HiFi Test 04/2008

The HiFi Test Magazin tested the Teufel System 4 against five other competing systems of the same price class in the July/August issue. This test victory made us so excited, we had to include a short excerpt out of the total test here for you:

"In the end, there can only be one winner and the winner this time is the Berlin-based direct seller Teufel. It's amazing what the designers were able to put together for a total price of € 800,-. The most powerful subwoofer in this test is able to lay a solid bass foundation beneath the balanced sound of the satellites even in large home theatre setups."

Overall rating: A / "very good"

System 4 "Stereo 2.1" review of Area DVD
System 4 "Stereo 2.1" review of Area DVD
"Exceptional acoustic performance with elegant design."
Area DVD 03/2008

"The homogenous, highly dynamic sound and detailed response of this system are very unusual in this price category. On top of this, the System 4 offers outstanding transparency in the high frequency range. Voices are always clear and highly intelligible. The very powerful active subwoofer blends harmoniously with the other speakers and has sufficient reserves to handle even the most thunderous special effects. At the same time, it is also sophisticated enough to handle demanding musical material smoothly. The two very compact dipole speakers are responsible for the lively, dense surround sound experience."

• Surprisingly detailed response
• Very clear separation of voices and instruments
• Full, atmospheric rear channel sound
• Outstanding SPL-handling capacity
• Active subwoofer with amazing depth
• Very good performance in stereo mode

Price/performance ratio: 10 / 10 stars

Help regarding this product
Will the System 4 harmonise with my receiver?
The System 4 can be successfully combined with a wide range of AV Receivers providing that they have output performance of at least 5 x 40 watt sinus.
Can I order the Teufel speakers in different colours than those offered?
To realise the very reasonable sales prices usual for Teufel, it is not possible to offer the speakers in a multitude of housing designs.

This circumstance would drive up the production and storage costs, which would result in a significantly more expensive sales price.

A paint shop in your vicinity will surely be able to repaint the speaker housing to your preferred colour without loss of warranty - after expiry of the eight-week right of return.
Kann das System 4 meine HiFi-Boxen ersetzen?
Auf jeden Fall. Das System 4 ist ein vollwertiger Ersatz für Stereo-Standlautsprecher und für Musikwiedergabe wie Heimkinoton geeignet. Lautsprecher Teufel ist Pionier auf dem Gebiet hochwertiger Satelliten-Subwoofer-Kombinationen. Wir garantieren Ihnen mit einer sorgfältigen Entwicklung der Satelliten M 400 FCR einen Stereoklang vergleichbar mit deutlich teureren (und vor allem größeren) Standboxen. Ein Standard-Lautsprecher müsste schon etwa die Größe eines Kühlschranks haben, um einen tiefen Bass wiederzugeben, der mit einem separaten Subwoofer wie dem M 4000 SW vergleichbar ist. Mehr Informationen zu diesem Thema finden Sie hier: HiFi im Heimkino?
Do I need the same cable length for all speakers?
In our experience, there is no acoustical difference for different cable lengths for lengths up to 15 metres.
The RAMPA insert at the bottom of the speaker sometimes is turned out with the tamping screw. What can I do about that?
Unscrew the tamping screw from the Rampa insert and screw the Rampa insert back into the bottom of the speaker.
