The embodiment of Raumfeld by Teufel’s audiophile standards, the Raumfeld Speaker L is the world’s first active high-end floor-standing loudspeaker with complete streaming functionality.

The best of Raumfeld and Teufel in a very stylish design

You no longer have to compromise on sound if you want to stream music. The Raumfeld Speaker L is an active WLAN loudspeaker with simply amazing sound. The Speaker L’s elegant appearance is the worthy expression of the sophisticated technology within: two 170 mm bass drivers with stabile yet lightweight carbon membranes, a 130 mm midrange driver, and 28 mm tweeter fired by an extremely noise-free amplifier combined with faultless linear tuning ensure a superior sound experience. SFT Magazine noted of the sound:

“Acoustically, the Speaker L is remarkable for its neutrality. The speakers sound natural, balanced, and do not emphasise any one frequency range over the other.”

The Raumfeld Speaker L is able to stream from various devices and reproduce breathtaking sound. Even non-compressed files can be streamed and played back thanks to advanced Raumfeld by Teufel technology. A free Raumfeld App allows you to control streams of music stored on your Apple iPhone/iPad/iPod (iTunes) or Android device directly to the Speaker L freeing you from cables, PCs, or intermediaries of any kind. The Raumfeld App allows you to access a wide range of online music streaming services including Spotify Connect as well as Internet radio stations; and you can enjoy this inexhaustible font of music without any loss of sound quality or interruptions. As Area DVD noted in their enthusiastic review of the Speaker L:

“Its uninterrupted signal transmission is to be commended.”

Raumfeld by Teufel products are characterised by an astonishing expandability. The Speaker L is no different and can be easily integrated into an existing Raufeld system or with other Raumfeld products. Enjoy multi-room as well as multi-music flexibility. Cable-free streaming of different or the same music in one of more rooms can be easily achieved at the touch of a button.

The Speaker L is the uncompromising audiophiles‘ choice when it comes to streaming and perfect for music lovers who want access to the huge variety of music offered by online music services without sacrificing sound quality. The Speaker L dispels any lingering doubts about the ability of streaming to deliver high-quality sound.

Raumfeld Stereo L – Design"The Stereo L floorstanders are big and imposing but gobsmackingly good-looking. Standing a princely 1145mm tall by 220mm wide, they’re finished in a luxurious white lacquer that contrasts stylishly with the large black magnetic grilles. These grilles rest on a brushed silver block bearing the Raumfeld logo, while the whole thing sits on a thick black plinth that creates a gap for the bass reflex vent at the bottom.Build quality is phenomenally good, every bit as robust and rigid as we’d expect for the money, although at 27.5kg and 24.2kg we don’t recommend lifting them out of the box without help. Pull off the grilles and you’ll expose a 130mm midrange driver, two 170mm woofers and a 28mm tweeter, all housed in a thick metal baffle that adds to the overall sense of luxury."...Raumfeld Stereo L – Performance"Based on our impressions of the Stereo Cubes, which deliver an incredibly refined and entertaining sound for £400, we were expecting amazing things from these bigger, pricier speakers. They didn’t disappoint.Poised and punchy with bags of energy and detail, Stereo L musters a remarkable sound. It laps up anything you throw its way, be it jazz, rock, pop or hip-hop – every instrument, vocal line and rhythm is played with purpose and spine-tingling clarity. It throws out a big, muscular sound that fills the room, no matter how cavernous."

"[T]he new version of the Speaker L [clearly] illustrates that the many small improvements achieved a positive effect overall: A balanced foundation and extremely neutral midrange is built on a powerful and deep-reaching bass foundation. Powerful and finely details highs are added to the mix.”Conclusion:"Controlled via an Android or iOS smartphone, the floorstanding speakers offer a markedly self-confident and neutral sound from the deepest bass to the highest levels of brilliance. Along with a fair price and uncomplicated controls within a network (LAN or WLAN), the Raumfeld Speaker L Mk2 won us over with truly convenient music streaming.”

Testbericht - smartaudio - Raumfeld Speaker L - sehr gut 10/2014

"The days when you needed a whole host of devices in your living room are over. Raumfeld wants to prove that two loudspeakers are enough.”"The lynchpin of the Raumfeld operating system is the app. From this, other audio sources are chosen.""In the listening test, we started out with [...] a jazz piece. In it, the uncompressed WAV file was played back by the loudspeakers with exceptional dynamics. The plucked strings of the upright bass sounded wonderfully alive and agile. The tonal quality was also very good. Thanks to the markedly well-tuned midrange, the instruments played on a well-defined virtual stage.“"Our next selection was LL Cool J’s new album "Authentics" with which the Raumfeld speakers impressively displayed their abilities in the bass and low end. The bass lines were presented in our listening room with well-dosed amounts of pressure while Seal‘s perfectly reproduced soulful voice really knocked us off our stools.”"The sound is perfected by nuanced and brilliant tweeters that subtly yet emphatically enrich the overall acoustic performance of the Speaker L."Translated from the original German.

"Whoever purchases a Raumfeld loudspeaker gets a complete hi-fi system in the bargain. [...] The era of having to accomodate an armada of electronic devices in one’s living room has passed. Raumfeld wants to prove that two loudspeakers are all you need.” "The Raumfeld control system is based on and centers around a free app. [...] In order to ensure potent audio playback, the Speaker L loudspeakers make exclusive use of high-quality technical components. In this way, the loudspeakers operate with a high-performance arrangement of drivers that are conceived according to a 3-way arrangement.“ Sound "We started off with a few jazz pieces [...]. The plucked strings of the upright bass sounded exquisitely alive and agile. The tonality is likewise good. Thanks to strong tuning in the midrange, the instruments play on a perfectly outlined virtual stage.” "The sound image is perfected by the high-definition, brilliant tweeters that enrich [...] the acoustic overall performance of the Speaker L loudspeakers.” Test result "The streaming loudspeaker system, the Speaker L from Raumfeld, expertly unites the most cutting-edge technology with a flexible variety of use scenarios. Thanks to multiple functions, the Raumfeld system can be recommended for smartphone and tablet users who desire first-class sound quality and contemporary user comforts."

Testbericht - HiFi Test - Raumfeld Speaker L Highlight

"Both loudspeakers are equipped with first class drivers which were thoroughly improved for the new Stereo L (previously named the Speaker L Mk2). A bass reflex enclosure and two long throw woofers with carbon membranes ensure plenty of bass dynamics down to 35 Hertz on either side of the stereo pair. In addition, a coated 110 mm cellulose membrane for the midrange driver and a tweeter with a 22 mm diameter show their musical trump cards.”In practice"The initial startup with the Raumfeld Stereo L is joyously simple. An app that Teufel provides free of cost for iOS and Android devices is all that is needed to control the system.”"The imaging is first rate. Musicians are accurately placed in the room; the virtual stage is realistic and unfolds in an exciting manner. The Stereo L creates a sound that in part operates at the level of a much more expensive loudspeaker and includes its own active electronics and integrated streaming technology in the bargain.”Conclusion"The new Mk2 version of the Raumfeld Stereo L loudspeaker makes it easy to stream music at a very high level. […] The sound in this new version is even more commanding and neutrally tuned and offers high fidelity from the deepest bass to the highest treble at a very fair price.“Translated from the original German.

"They set an acoustic standard that goes well beyond their price class and are also extremely flexible in their capacity as active streaming speakers."

"The Bauhaus style Speaker L with its timeless design and carefully applied matte white lacquer features a stand in contrasting black as well as a protective grille over the drivers neatly covered with black fabric. Happily, the protective grilles are magnetic and there are therefore no unlovely holes [...]Beneath the black baffle is […] a silver aluminium strip. In the middle of this on the master speaker is the volume regulator which has a pleasant feel. [...] The very stiff and solid MDF enclosure is exemplarily quiet even with high loads. The Speaker L does not give off any enclosure noise.”"The Speaker L Mk2 is the absolute master of the situation. There is no dynamic compression, no enclosure noise, […], no banging of the bass membrane. The level stability is first class [...]. The acoustic maturity of the Raumfeld Speaker L generation Mk2 both astounds and inspires.“"The very 3-dimensional overall presentation is held together by an enormous dynamism that is sustained even at very high levels. [...] This well-thought-out balance is exactly what characterizes the largest of the Raumfeld speakers: Always in the center, but never disruptively pushing to the fore.”"Praise for the Speaker L Mk2: Great shaping of vocal reproduction, lively overall acoustics, rich dimensionality – top, without reservation. [...] One doesn’t need anything other than these two large floor-standing speakers to enjoy a sound quality at a completely fair price that some stereo systems with a similar set up – that is, with an amplifier, CD player, and speakers – that cost twice as much can’t meet. [...] The Speaker L Mk2 is a prime example of the way modern music is listened to – with a combination of flexibility and high-end sound quality.“Conclusion"Depth, level stability, braod and fine dynamics – in all disciplines, the Berliner loudspeakers prove to be way above average. They set an acoustic standard that goes well beyond their price class and are also extremely flexible in their capacity as active streaming speakers. They are therefore true show pieces [...] The Speaker L Mk2 offers a mixture of strong sound, flexibility, and a price/performance ratio that is without rival at the present time."Translated from the original German.

"The balanced playback of the upper range, [...] creates a a very homogenous integration of individual instruments into the whole."

"What began as a compact multiroom system has advanced into a full-fledged streaming set that stands alone without equal in the new 2.0 generation." "Both loudspeakers can be operated with nothing more than a Wi-Fi access point and a corresponding Raumfeld App or, alternately, the Raumfeld Controller. An additional loudspeaker input enables the Speaker L to be connected to an A/V receiver or stereo system with integrated amplifier.” "A slightly horn-shaped driver that’s responsible for the directional sound is located on the same acoustic dispersion plane as the midrange driver. This construction makes the spatial unfolding oft he sound markedly noticeable without the need to force the optimum from the crossover or via a DSP guided correction of differences in propagation time.” "When it comes to tuning the Raumfeld Speak L2, Teufel gets a lot right and forgoes an overly exuberant tone. The sound design is heavily invested in deep bass playback, something that will please many music enthusiasts. On the other hand, any form of harsh or sharp tonality is utterly absent from the loudspeakers. Vocals are not unnecessarily pronounced. The balanced playback of the upper range, [...] creates a a very homogenous integration of individual instruments into the whole. The optimized mid-to-high range enables playback with well coordinated propagation times which ultimately supports the spatial imaging on the acoustic stage. Modern and symphonic works benefit from this in equal measure [...]. An additional room configuration menu enables [...] playback according to one’s own preferences which makes the Speaker L2 the most acoustically versatile loudspeaker in its class.”

"Raumfeld - the name already sounds superior. [...] Three different stereo speaker systems, a one speaker solution and – last, but not least – the Raumfeld Connector for connecting an existing hi-fi system combine to create a product range that just about satisfies every requirement. All components communicate with each other via accessible WLAN through which they also have access to music libraries available in the network [...]. In addition, Raumfeld naturally has command of Internet radio and various streaming services [...].” Conclusion "Those who are not just looking at comfort when it comes to multiroom, but maximum sound quality as well should take a closer look at Raumfeld. The system plays nearly all file formats, including many lossless and high resolution varieties, and therefore guarantees maximum music enjoyment with minimum cabling effort.”
