Teufel Stereo L Bedienung
Lucky Man
Owners of the Stereo L can count themselves lucky. Because there is simply no better sound from a streaming speaker. A total of three bass drivers, a mid-range driver and a tweeter deliver powerful yet detailed sound from every source.

After 2.5 years of research, Teufel has developed an extraordinary driver in the form of the coaxial flat diaphragm chassis. Thanks to SCA (Synchronised Coaxial Acoustics) technology, this works almost like a pointed sound source, which guarantees very little difference in transmission time between mid-range driver and tweeter.

The tweeter and mid-range drivers are fused into one component. Almost all transmitted frequencies reach the listener's ear at the same time, resulting in a particularly natural sound reproduction.

As a result, different sounds (e. g. voices) are perceived, as in reality, as spatial sources and can therefore be precisely located. Overall, the 3D reproduction appears more realistic than it would with a separate tweeter.

The SCA coaxial chassis is also used in the Definition 3 and has already won several awards.
Extra-large tweeter for silky high-tones and low distortion, even at high volumes. Wide beam angle for best sound quality even when not sitting directly in front of the speaker.
Mid-range driver
This is arranged around the tweeter and offers a high level of impulse fidelity, and therefore precise sound reproduction, with its light and stiff diaphragm.
Teufel Stereo L
Three bass drivers
Made from carbon woks, so is also very light and low distortion for a high impulse response and deep, precise bass.
Moving coil
Highly resilient, for high distortion-free levels.
Everything goes
The Teufel Streaming speakers are fully compatible with other systems and services. Thanks to the extensive connection options, they can be transformed into a docking station.

Teufel Stereo L review of Audio
Teufel Stereo L review of Audio
"This is multi-room!"
Audio 08/2018
"[...] the Stereo L does exactly what the M had already done, only better."

"A perfect symbiosis of Teufel Definion speakers and active electronics from Raumfeld - that is our conclusion. The seamless integration of the two active stereo speakers into a multi-room system with sounddecks and bars, small and medium-sized music systems - this is currently only available from Teufel. The sound is great, the design too, and the app is super. This is multi-room!"

Teufel Stereo L review of www.connect.de
"An impressive multi-room active speaker with a sophisticated operating concept"
www.connect.de 26.04.2018
"[...] If you take the bass down a little bit, you have a very well-balanced loudspeaker in front of you, which is not only rich in contrast and detail, but is also extremely lively. Even with complex material such as Moritz Moszkowski's “Fakeltanz” the speaker got along surprisingly well. It was able to transmit the orchestra down to its finest parts and even in the faster runs it showed a precise timing that you don't hear in every speaker with such high precision.”

"In the louder passages and especially in the finale, it showed a touch of brutality that did not damage the mood of the play. On the contrary. Here it was once again impressively shown that the Teufel Stereo L can do one thing above all: have fun."

"An impressive multi-room active speaker with a sophisticated operating concept and an equally impressive sound image that also meets higher demands in terms of imaging and fine structure".

Teufel Stereo L review of Audio Test
Teufel Stereo L review of Audio Test
"a real all-rounder"
Audio Test 03/2018
"All in all, the Teufel Stereo L speakers are real all-rounders. They are particularly entertaining because of their extremely successful representation of spatiality and depth as well as the detailed separation of the signal sources. We did not get the impression that they are 'only' Wi-Fi or multi-room speakers or multi-room during our test. Many a classic floor-standing loudspeaker can take a leaf out of Teufel's [...] Stereo L book."

"The large active devices from Teufel with multi-room function are not only impressive because of their range of functions and many connection options. Their sound makes them a real competitor for passive floor-standing loudspeakers with a significantly higher purchase price. The Stereo L is incredibly vibrant and vivid, making a subwoofer superfluous."

    Help regarding this product
    Why doesn’t my BOOMSTER/BOOMSTER XL/BAMSTER/BAMSTER PRO/BAMSTER XS/ROCKSTER XS sound as good with my Windows PC / notebook?
    It could be that the speaker is connected as a device with speakerphone function. Please go to: settings menu > devices and printer > BOOMSTER (or other Bluetooth device). Right click on the device and remove the check mark next to the “speakerphone” option.
    My devices' wireless signal is permanently low or breaks down frequently
    To gain an overview over the signal strength of each Raumfeld devices in your network, open Settings > Network > Network Analysis.

    A Loss of WLAN Signal

    The constant loss of a device's Wlan signal even at high signal strength is due to interferences with other wireless networks. By changing the Wlan channel, you eliminate this interference and can fix this issue. Should your system contain a Raumfeld Base simply try out different channels as described in the online manual (Modifying of the Channel Setting (Raumfeld Base)) and see if the signal strength becomes steady. Access points from other manufacturers usually offer an according configuration option in their administration interface. 

    Alternatively you may contact our service team, which is happy to assist you with the detection of the best channel available.

    B Constant Low Signal Strength

    If the signal strength of individual wireless devices is constantly beneath 50%, steps should be taken to upgrade the Wlan reception of the device and therewith the music playback reliability. In most cases it is sufficient to reduce the distance or the number of obstacles between your Raumfeld Base and your playback device. Simply check out if the reception increases when positioning the devices at different places.

    In general, the less walls and ceilings between the devices, the better the reception is. Thick walls made from concrete or clay brick will especially abate the signal. Often a relocation of a few centimeters is enough to bypass any problems.

    Mind the following advice that accounts for both, systems with Raumfeld Base or systems that are run with an access point from another manufacturer:

    • Position the Raumfeld Base or the third party access point you utilise rather high up, on a cupboard for example. Make sure there's some space towards the wall. Do not position the device on the floor or in a corner.
    • If you make use of a wireless phone there may be interferences with the wlan signal. Therefore, do not position the Base or the third party access point you utilise right next to the phone's base station.
    • Set up the devices in a way that ensures there are a minimum amount of obstacles inbetween your access point and the playback device. Avoid setting up the Raumfeld devices in alcoves or behind prominent corners.
    • Make sure there are no large-scale metal bodies between the access point and playback devices (e.g. radiators or fridges)
    • Large plants may also block the signal due to their moisture content and should not be between the access point and playback devices.
     If the reception does not increase after a repositioning we suggest using a standard Wlan repeater or to connect single components of your Raumfeld system with your existing wireless access point (see Connecting of your Raumfeld devices with your personal access point in the online manual). Please contact our service team to find the perfect solution for you.
    I’m only able to access the Raumfeld Zones under “available devices“ in my Spotify App. How can I control the individual rooms?
    Deactivate the Multiroom Mode for Spotify in the Raumfeld App by switching to the "off“ setting. You will then be able to individually control each device in the Spotify App.
    Every title in my compilations are being shown as their own album
    Compilations or soundtracks are normally composed of various artists. In order to display them as a complete album, the tracks of a compilation must be grouped.

    There are many different methods of accomplishing this, assuming that the same album name, or Album Tag, is assigned to all tracks. 

    • Assign the name of the compilation's producer to the tag Album Artist. Use "Various Artists" if the producer's name is unknown.
    • If you use iTunes, you may select for every song that they are Part of a Compilation under Get Info > Info.
    • As long as the album is stored locally on the Raumfeld Base, a network drive or USB storage, it is sufficient to simply save the music files in the same folder. Make sure, however, that only music files pertaining to the compilation are stored within this folder.

    In order to edit your music collection's tags, we recommend the following programs:

    Media Players
    • iTunes (Windows, Mac OS; only supports MP3, AAC, M4A, Apple Lossless)
    • Windows Media Player (Windows; only supports MP3, WMA)
    • Winamp (Windows; supports the same formats as Raumfeld except for WMA, WAV)

    Special Tag-Editors
    • MP3-Tag (Windows; supports the same formats as Raumfeld except for WAV)
    • MusicBrainz Picard (Windows, Mac OS, Linux; supports the same formats as Raumfeld except for WAV)
    I copied new music to a network share. Why isn't it displayed under My Music?
    When you copy new music to a network share you have to manually initiate a rescan in order to see the music on your Controller or in the Raumfeld App, respectively.

    In order to do so, go to My Music > Recently Added and tap the button "Update music index" on bottom of the list. Alternatively, visit Settings > Music Resources and activate a scan for new music on the music resource you've copied the music to.

    Under Settings > Music Resources there is also an option to make your Raumfeld System check for new music every day. A manual scan is then not necessarily required.
    Can different music (Multicast) be played in different rooms?
    Multicast (different music in different rooms) is possible with Spotify, but not simultaneously. Due to certain restrictions stipulated by the provider, simultaneous multicast is not possible at the present time.
    I use a version 6.0 Android device and am trying to set up my Wi-Fi streaming system. The setup assistant, however, does not continue after the initial screen. How can I proceed?
    Make sure that your smart device is signed in to your home WiFi – the same WiFi network you plan to use with your Wi-Fi streaming system. If you are already signed in to your WiFi network, deactivate your smart device’s access to mobile internet for the duration of the setup.
    I use an Android device version 6.0 or higher. The music I stream directly from this device drops after a short time. What could be the reason for this?
    One reason could be that your smart device is going into standby mode and dropping the connection.

    Solution: Add the Teufel Raumfeld app to your standby exception list, also known as your device’s “whitelist.” To do this, go to “Settings” in your Android menu and then “Apps,” “Advanced,” “Battery optimization,” “All apps” and “Raumfeld.”
    Can I use my home cinema with the Teufel Streaming system?
    In order to use your home cinema system with your Teufel Streaming system you require a Connector:

    • Connect the analogue or digital output of the Raumfeld Connector to an appropriate input of your home cinema amplifier
    • Connect an analogue output of your amplifier to the analogue input of the Raumfeld Connector

    This will allow you..

    • to listen to music from your Teufel Streaming system via your home cinema system
    • to stream the audio signal of TV series or movies into other rooms of your house

    Please note that there will be a short delay between video and audio signal when you stream it into other rooms. If you choose to play the audio signal via your home cinema system only, audio playback is of course in perfect sync with the video signal.

    Do I need to be experienced with technology (WLAN, SSID, WEP, computers, internet, programming)?
    Knowledge about wireless networks or computer technology is not necessary for setting up or using the Teufel Streaming systems. New devices are added to the system simply at the touch of a button.
