Features
All technologies at a glance


Discover spatial sound
All speakers have the same acoustic equipment, which therefore produces the same sound quality and always guarantees an immersive surround sound experience. Even the central speaker has the same drivers. Only Teufel takes care of such details.

Easy integration
Each sleek column only takes up the equivalent of an A5 sheet of paper in terms of floor space, which makes the system easy to position, even in smaller rooms. The elegant aluminium exterior looks good in any setting.

Quality you can see as well as hear
The LT 4 loudspeakers are made entirely from brushed aluminium – a very expensive but stable material that is perfect for loudspeaker construction thanks to its noise-reducing qualities. Aluminium has the added advantage of giving the loudspeakers a subtle elegance that fits into any living room.
Sound with perfect power and grace
The LT 4 takes movie soundtracks, music, and games and transforms them into sonic events you can feel. The following acoustic features make this experience possible:
- A 3-way system distributes the incoming audio signal from the A/V receiver to five different drivers that are optimized to play back their dedicated frequency ranges. This results in a better sound than that produced by a 2-way or broadband system.
- A total of four larger 75 mm midrange drivers ensure full, deep playback. The only thing thin about this system is its columns. .
- Long-throw drivers produce high, precise and distortion-free levels
- A large 20 mm tweeter endows voices and effects with a silky, highly detailed tone without sounding shrill or aggressive
- In spite of the slender columns, the crossover frequency to the subwoofer was set at 120 Hz. This makes it difficult to localize the bass which means more flexibility when positioning this speaker in the room.
- The lightly slanted corners on the columns and satellites produce a large, horizontal dispersion angle so that an extraordinary sound can be enjoyed in every listening position.

Easy setup and installation
The slender standing columns are securely positioned on a massive aluminium base. The centre and the shorter columns have integrated wall mounts. It is also possible to place the centre on an included plate. Each loudspeaker is equipped with sturdy, gold-plated screw terminals. These can be used with cables with diameters up to 2.5 mm² .

Impaq 8000 Blu-ray Receiver
The Impaq Blu-ray A/V receiver is a Blu-ray/DVD/CD player, AV receiver, network player, radio and much more. You won’t require any other device to enjoy 5.1 surround with the best possible sound and greatest number of playback options. A single slimline receiver measuring just 8 cm tall is all you need.
The Impaq 8000 delivers balanced sound and stable levels across the entire frequency spectrum. A highly efficient class D amplifier from Texas Instruments gives the little system plenty of power.
The system's ability to process and decode video content is also state-of-the-art. Not only does the Impaq 8000 support this standard, an integrated upscaling function can convert HD content into 4K.
PlayStation 4, Xbox One, Wii U, television, SAT or cable receiver, Apple TV, smartphones and tablets can be easily integrated itno the system via one of the Impaq's HDMI, digital or anlog inputs.
7.1 option: An RCA pre-out connection on the back makes it possible to expand 5.1 into 7.1 setups. Note that active speakers must be connected to the pre-out. With a Rear Station 4, even passive speakers can be integrated and wirelessly controlled.

Bluetooth, radio, streaming
The Impaq not only streams via Bluetooth, it offers the highest quality sound via aptX codec. This makes it easy to play back audio from apps like Spotify, Apple Music and YouTube and enjoy CD-like sound quality. Thanks to NFC, the pairing procedure is also easy: Just hold your smartphone up to the Impaq and the two devices will automatically forge a Bluetooth connection.
In addition to Bluetooth streaming, the impaq can access data on your home network and play back all the movies and music you have stored there. Pictures can also be acceessed and displayed on your television. Connect your smartphone to your home network and transfer all the music, videos and pictures you have stored there.
An oldie but a goodie, the Impaq 8000, of course, also includes FM radio. Save up to 30 stations thanks to the Impaq's RDS function.

The optional Wireless Audio Set, available separately, allows you to control the rear speakers wirelessly.

Premium flat active subwoofer
The T 4000 SW bridges the divide between easy room integration and mega bass playback. An incredibly flat enclosure makes it easy to place the T 4000 where it won’t get in your way. That small space behind the sofa or coffee table is enough. In fact, the T 4000 is so slender, it can even be positioned under most sofas, wall mounted or used to support your television. Its highly robust, reinforced MDF enclosure was designed to withstand the weight of conventional televisions making it the ideal sonic pedestal.
In spite of its highly convenient dimensions, T 4000 is driven by 250 watts for power to spare. A three driver system that is already successfully employed in Teufel’s highly popular System 4 THX model is used here as well. This ensures balanced playback based on THX standards and produces powerful, deep bass all the way down to 35 Hz for home cinema that makes you part of the action. Even very high levels are accompanied by very little distortion thanks to the long throw-drivers used.
The T 4000 is a universal subwoofer that can be combined with just about any home cinema set, even very high-performance models. This means the T 4000 is perfect for accompanying surround speakers or for giving an already complete 5.1 set an extra boost.

Suitable for the transmission of images (including 3D) and sound (including HD) between devices such as Blu-ray players, TVs, AV receivers and soundbars.
