This speaker is a model full of dynamic energy and enthusiasm. Weighing in at only 35 kilograms, the 1.15 meter high and 0.5 meter deep M 520 F offers immense mass and volume capacity, which is put to optimal use based on precisely and efficiently engineered technology.

Neodym tweeter and monumental bass

The column contains two 2 x 160 mm carbon fibre midbass drivers and a 25 mm neodym tweeter, and is supported by a laterally emitting 300 mm woofer. The result of this configuration is a conveniently thin front end combined with monumental bass reproduction. The integrated woofer functions as a pure subwoofer which is coupled at 80 Hz and driven by a separate 190 watt amplifier. Due to the universal design of its rear terminal area, the integrated active subwoofer can be activated by either the sub-out output of an AV receiver or the speaker terminals of your stereo amplifier. In any case, the amplifier/receiver is no longer required for bass reproduction, lending improved ease to the other frequency ranges.

Active/passive construction

The M 520 F offers a simple way to dramatically improve the bass quality of your stereo system or add two subwoofers to your home cinema system. A three-stage volume selector switch allows you to assign various weights to the subwoofer and tweeter/midrange ranges so that the column speaker can be adjusted to various space requirements. This active/passive construction is effective down to 30 Hz and can generate a breathtaking volume level of 105 dB/meter! This makes these column speakers capable of filling an entire 50 sqm room with sound.
 
D'Appolito configuration

The M 520 F provides clear proof that the easiest way to get the best results is to rely on “classical” methods: increased housing volume, large cone surface, solid chassis technology, proven D'Appolito configuration plus a great deal of “inspiration” (see active/passive subwoofer in the column speaker). As a result, this pair of M 520 F column speakers can deliver stereo sound whose quality will simply blow you away. Of that we are certain.

Specifications

Hybrid Speaker M 520 F
Hybrid Speaker M 520 F
Here is a speaker that is never shy and reserved – to the contrary, it has an explosive dynamic range that begs to be cranked up. Weighing in at 35 kg, the M 520 F is 1.15 m high and 0.5 m deep, thus having an immense capacity in terms of mass and volume. This capacity is put to optimal use thanks to the precise and inspired engineering from Teufel.

This floorstanding speaker contains two 2 x 160 mm carbon fibre woofers, a 25 mm neodymium tweeter and a side-firing 300 mm woofer. In this configuration, the front panel can be conveniently narrow even though the speaker has monumental bass response. The integrated bass driver functions purely as a subwoofer coupled at 80 Hz and driven by a separate 190 W amplifier. The universal connectors on the rear terminal allow the integrated active subwoofer to be connected to either the ‘Sub Out’ of an AV receiver or the speaker terminals of your stereo amplifier. In any case, this relieves your amplifier/receiver from bass duties and frees it up to concentrate more on the other frequency ranges.

Using the M 520 F, you will dramatically improve the bass response of your stereo system. In home theatre environments, you will effectively add two subwoofers to your system. A three-stage volume selector switch allows you to select how much bass is split between the subwoofer and tweeter/mid-range drivers and thus match the system to your listening environment. This active/passive construction is effective all the way down to 30 Hz and can generate breathtaking sound pressure levels as high as 105 dB/m!

"Full bass, excellent mid-ranges and clear listening."
AV Magazin.de 11/2008

The test subject sent over from Teufel played from the beginning with good detail and finely harmonised dynamics. An imposing orchestra played in all voices equally well. Even if it's lacking in higher frequency spectrums here and there, the M520 F makes up for it with its cleanly graduated representation.

Thundering drums and spirited strings play equally with expressive character. The acoustic underpinnings of the subwoofer to the included Satellites work fantastically, with the high, mid- and low ranges flowing together. Large and heavy bass drivers present themselves with the M 520 F with an acceptable group delay. The bass range is seamlessly implemented in the sound and plays together hand in hand with the agile but light midrange drivers. (Which can’t be taken for granted, especially with a standing loudspeaker of this price class.)

To bring the broad bass drivers out of the shadows, we placed some demanding classical music into the player. The Hip Hop CD "Tarantula" (from US rapper Mystical) and the album "Shock Value" (from Timbaland) really bring out the deep, powerful bass.

The dynamically compressed but still well co-ordinated baselines and kick drums are blasted unfiltered and powerfully into the listening area. Through the large hub capacity of the boxes are out there every time and fully heard – by you. With an almost unreasonable nonchalance, the two stand loudspeakers throw it out into the test room. And that makes us very happy. The M 520 F is a solid loudspeaker, that, very simply, makes it fun again – and that in the classical stereo area as well as the multi-channel setup. Full bass, neutral mid-ranges and clear listening – a powerful construction.

In plain words
The Berlin music-smithy can always be counted on for a real surprise. With the M 250 F Teufel offers an acoustic goodie at a seductive price. The symbiosis between the active and non-active technology works out devastatingly good. The thin stand boxes sound commanding, thanks to the included subwoofer, are cleanly made and please the eye with their contours. Measured against its price, the play is unequalled in its price class.

Help regarding this product
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.
What are the volume switches for?
The sound of the speaker always depends on the room where it is located.

The volume of the active subwoofer can be controlled so that you can adapt the relationship between the active bass and treble / mid tones to suit the room.

Use your own senses to judge which settings sound best in your room. This switch is especially useful in stereo mode. On the other hand, multichannel amplifiers often have technologies that adjust the subwoofer volume - so when using a multichannel amplifier the controller should first be set at 0dB.
How do I connect the hybrid speakers to my AV Receiver?
The hybrid boxes are treated just like two normal active subwoofers. You will need a Y adapter that doubles the sub out output of an AV Receiver. Each one of these now two outputs are connected to one column speaker with one mono RCA cable each. At the back of the column you will find a corresponding "Line In" input in cinch format.

You will also find the "Line" switch at the back which ensures the optimal filtering and polarity of the subwoofer.
How do I connect the M 320/ M 420 F/ M 520 F hybrid speakers to my stereo amplifier?
The M 320/ M 420 F/ M 520 F hybrid speakers are treated like two normal passive stereo speakers and connected to the speaker outputs of the amplifier with two-pole speaker cables. At the back of the column you will find a corresponding "High Level" input.

The "High Level" switch also located at the back ensures the optimal filtering and polarity of the subwoofer.
Is the M 320 F/ M 420 F/ M 520 F from the Theater 3 Hybrid home cinema set suitable for hi-fi?
In every way.

Teufel does not artificially differentiate between home cinema and music playback. The objective of the speaker is to consistently achieve the original playback quality created by the sound engineer in the studio. As such, it is a fully adequate replacement for your old stereo system. After all, Lautsprecher Teufel is a pioneer in the sector of high-quality satellite - subwoofer combinations.

Even if the M 320 F/ M 420 F/ M 520 F look like standing speakers - technically they are a subwoofer/satellite combination.
Doesn't the M 320 F "break" with the Teufel philosophy of satellites and subwoofer combinations?
Not at all.

The column is nothing other than a closed two-way satellite (the centre speaker) set vertically on a narrow active subwoofer and combined in one collective housing (but separated acoustically). As such, it is a partially active subwoofer/satellite combination in the guise of a conventional passive standing speaker.
