The next big thing

The ROCKSTER makes XXL sound a reality wherever you need it. Without a professional sound installation, you can transform your next grill party, outdoor football viewing, block party or backyard celebration into the event of the season. 

Complete portable party sound

An integrated 2-channel DJ mixer with a 3 band equalizer, channel fader, prelistening function and individual source selection for every channel lets you do much more than just blast music with the ROCKSTER: You can mix the perfect sound for all your events. Simply connect two smartphones or MP3 players for the ability to create your own mixes. An instrument input lets you feed the ROCKSTER signals from electric guitars and e-drum kits.

And because you’ll want to protect your sound console from the odd fermented beverage, we’ve equipped the ROCKSTER with a sturdy cover. A rain cover for extra protection from the elements can be purchased separately.

Combine ROCKSTERs for an even bigger sound

The ROCKSTER can fill a football pitch with sound all on its own, but the principle of stereo sound applies here as well: Two speakers sound better than one. This is especially true when each speaker plays its own dedicated channel. That's why we designed the ROCKSTER with the ability to connect to another ROCKSTER via speaker cable. Each speaker can be made to play either the left or right channel simply by flipping a switch on the control panel. The result is an enormous soundstage without equal. Depending on how your ROCKSTERs are arranged, you may want to have each speaker play in mono. To do this, simply select the mono option from the control panel. A mono arrangement and can come in handy when multiple ROCKSTERs are connected to each other.

Bluetooth battle

The ROCKSTER is equipped with 2 Bluetooth inputs, allowing two separate people to feed the beast with the perfect sonic material. While one song waits in standby, the other can play for flawless transitions between tracks. The use of the advanced aptX codec ensures a rich transparent tone with music transmitted via Bluetooth within a 10 meter radius.

You can’t stop the ROCK

The ROCKSTER can be powered in three different ways:
1. With an integrated battery with a run-time of up to 8 hours
2. Via a standard 12 volt car battery
3. Via standard 230 volt mains power

ROCKSTER (2016) review of SFT
ROCKSTER (2016) review of SFT
"It can Watt?!"
SFT 04/18
"It can Watt?!"

"Teufel has taken the opportunity to revise their Rockster for a new generation 2017 model. The battery life has been considerably improved from eight to 20 hours. In addition, the maximum sound level increases from 115 to 121 dB - making it sound almost twice as loud as the Rockster Air. The engineers have also lent a hand to the sound itself. The frequency ratios have been re-tuned to make the Rockster 2017 sound even fuller in the bass and mid-range, while the treble is less sharp and therefore clearer. The radiation angle of the tweeter horn is also wider. That makes the Rockster sound authentic, even if you're not standing right in front of it."

ROCKSTER (2016) review of Allround PC
"The sound quality of the new Teufel Rockster is unshakeable"
Allround PC 15.02.18
"[…] Teufel has also improved sound tuning and dispersion, further raising the Rockster to the Olympus status of the best portable speakers currently available for this price."

"The sound quality of the new Teufel Rockster is unshakeable; the 450-Watt class-D amplifier ensures that the dynamic sound remains balanced even at the highest volume levels, while the 380 mm woofer also gets the last party guests out of their seats and the neighbours to the door - at least fewer to party with. If you want to really turn it up, bring the Rockster with you to the park, because the volume is definitely sufficient for an open-air party."

"[…] In addition to a powerful but well-balanced sound, the rich range of functions also contributes to general entertainment. This is how the Teufel Rockster combines the best of party-boombox and professional equipment."

"...not just really loud, but also really good"
Die Welt 06.02.18
"[…] not just really loud, but also really good: the Rockster plays deep bass, which is [...] also clean even at dangerous levels."

"The mids and highs have to be helped by turning up both controls a little. Then there is clearer and more brilliant sound, altogether balanced and rich in detail."

"[…] The sound remains good after some fine-tuning. Teufel takes the volume crown back."

"In addition, the Berliners have amped up the battery life and improved the operation of the numerous connections and functions on the back of the monster speaker."

 "The Teufel Rockster is an impressive all-rounder that delivers great sound at any volume. The speaker creates an impression with its outstanding craftsmanship and solid appearance. Whether at a barbeque in the garden or a chilled evening with friends, this mobile soundsystem proves to everyone at the party who's boss."

ROCKSTER (2016) review of www.curved.de
"...louder than a Harley Davidson: the Teufel Rockster delivers above all on smooth, balanced sound"
www.curved.de 30.09.2016
 "No matter how high you turn up the volume, the high, mid and bass tones are adjusted smoothly, thanks to a Class-D 450 Watt amplifier.  The bass of the 380mm woofer impressed me in particular. So strong, yet so smooth, that you just want to cuddle up to it. That must be a first for a portable loudspeaker.
In our practical "road-testing", so not in a technical acoustic lab, the speaker reached an impressive 120dB. Which is even louder than teh 115dB that Teufel promised. Such a roar makes it able to fill even large halls with sound."

"Allrounder mit Höllenklang"
www.bild.de 27.05.2016
„Der Sound ist aber bereits in der Standard-Einstellung sehr gut. Ob Bombast-Rock (Pink Floyd, Deep Purple) oder Vocal-Jazz (Gregory Porter) bis hin zu schrägen Sounds wie die Peter-Gabriel-Cover von David Byrnes („I Don’t Remember“) und Lou Reed („Soulsbury Hill“) – der Rockster besteht nahezu jede Klangprüfung.“
„Selbst bei Maximum-Lautsärke verzerrt der Klang kaum.“

Fazit:

„Sehr guter Klang und hohe Flexibilität. Der Rockster lässt sich zwar nicht unter den Arm klemmen; einmal aufgestellt wird er jedoch zu einem echten Party-Starter.“

ROCKSTER (2016) review of www.lowbeats.de
"Even critical listeners will be surprised at the full, clean and incredibly assertive sound with an agile midrange and a pleasantly articulated presence range that ensures the necessary grip.”
www.lowbeats.de 28.05.2016
„Given its form and appearance, one naturally expects a corresponding high calibre sound from the ROCKSTER – and will certainly not be disappointed in this respect [...].“
"And yet the spectacular-appearing Berliner is far removed from being a mere noisemaker. Sure, the ROCKSTER wasn’t created to transport its listeners into the highest hi-fi nirvana; yet what it transports to the ear can be described without hesitation as having a refined sound. Even critical listeners will be surprised at the full, clean and incredibly assertive sound with an agile midrange and a pleasantly articulated presence range that ensures the necessary grip.”

"One thing that never ceases to amaze with the ROCKSTER is how unusually stable and tactile the sound image remains, even from a distance of several meters. In this way, one stay in contact to the music, even over large distances. The whole thing is carried by a fulminating attack-ready yet compact bass foundation.”

"Listening to music on the ROCKSTER definitely has a certain addictive quality. This is enhanced if one really pumps out the levels and lets the decibels loose. [...].“

Conclusion:


"Whether street music, barbecues, tailgating, student parties, neighborhood festivals or other outdoor events, the Teufel ROCKSTER doesn’t miss any opportunities to celebrate. As long as music is involved, it takes center stage. The ROCKSTER not only boasts a stylish offroad look, it offers sound than is more than just very good and which together with a nearly breathtaking level stability becomes the musical centerpiece of any event. In addition, it possesses tough qualities on the mechanical side that allows it to withstand even the most excessive parties without major injury. Also to be commended is the practical feature set. The highlights here are the integrated DJ mixer as well as the included battery which allows for mobile use even without access to mains power.”

ROCKSTER (2016) review of www.likehifi.de
"The power of the sound practically blows the listener away."
www.likehifi.de 28.04.2016
"When the music plays, the ROCKSTER’s power becomes apparent. The system really comes into its own at events. The power of the sound practically blows the listener away. Responsible for this is the 450 watt amplifier that drives an enormous 380 mm woofer to 115 dB. According to the manufacturer, the heavy chassis is especially tightly mounted, has powerful voice coils and a massive membrane. A high-performance tweeter ensures high, distortion-free levels. The broad dispersion angle guarantees a high degree of speech intelligibility over a wide area.”

Conclusion:

"With its gigantic dimensions and almost professional feature set, Tefeul’s ROCKSTER wasn’t made for a small home’s front porch. Instead, its strengths unfold in large outside areas and big rooms. The power packet is the ideal choice for accompanying musical events or athletic and dance groups.”

"Voor de wildere feestjes"
icreate 10/2015
Teufel Rockster - voor de wildere feestjes
We testen bij iCreate al jaren speakers en soms denken we alles wel zo'n beetje gehad te hebben. Maar nog nooit kwam er een speaker met een steekwagen binnengereden. Totdat de de Teufel Rockster werd binnengerold. Deze speaker is bijna een meter hoog en weegt 31,5 kilo: volgens Teufels eigen zeggen is de Rockster 'de Godzilla onder de luidsprekers'.
   
Heel veel knopjes
 Als je verbazing over de enorme omvang is weggeëbd, val je in de volgende verbazing. Er zitten namelijk enorm veel aansluitingen en knopjes op de acherkant. Alleen al om de Rockster aan te zetten heb je drie opties (een stroomkabel, auto-accu of de interne accu), er zijn twee aan/uit-knoppen en er is een schakelaar om de stroomstand te kiezen. De inputmogelijkheden zijn nog breder: een jack-kabel, dubbele tulp, mini-jack, XLR, en twee keer bluetooth (met twee pairingknopjes) en een masterinput met stereo-XLR. Was het dat? Nee, er zijn ook nog uitvoerpoorten voor de koptelefoon en een extra speaker. […]
   
Knalfeest

Uiteraard is de Teufel Rockster niet alleen zo groot om heel veel knopjes te herbergen. Godzilla produceert namelijk een 'monsterlijk' volume Je hebt 115 dB tot je beschikking, met diepe bas door de 15-inch subwoofer en duidelijke hoge tonen door de 1-inch tweeter. Ook bij dit hoge volume (we hebben het op vrijdagmiddag op kantoor even aangedurfd) worden alle dimensies nog steeds goed gebalanceerd weergegeven. Deze kracht is ruim voldoende voor de wildere feesten en om dat te benadrukken , is de Rockster zeer robuust gemaakt - hij kan tegeneen stootje en een omgestoten glas bier. Kortom: komt er wat familie op vistite, heb je een kinderfeestje of zit je 's zomers lekker in de tuin.... dan is de Rockster ongeschikt. Heb je een wild knalfeestje enwil je een stapje verder gaan dan een simpel afspeellijstje? Dan is de Rockster geweldig.

ROCKSTER (2016) review of www.krone.at
„Erstaunlich in jedem Fall“
www.krone.at 12.09.2015
„Ein 3,5- mm- und ein 6,3- mm- Klinkenanschluss, ein Cinch- sowie ein XLR- Eingang erlauben den Anschluss von etwa MP3- und CD- Player, Gitarre sowie Mikrofon, sogar mit Reverb und Limiter - optimal für all jene, die neben der reinen Musikwiedergabe beispielsweise in der Fußgängerzone vom Ende der Welt predigen oder einen auf Kelly Family machen wollen. Falls ein Tinnitus nicht genug sein sollte, lassen sich über einen zusätzlichen Audio- Ausgang sogar weitere Rockster in Reihe anschließen.“

„Erstaunlich in jedem Fall: Dank leistungsstarkem Hochtonhorn liefert der Rockster selbst im Grenzbereich noch einen verzerrungsfreien und überraschend ausgewogenen Klang. Erst durch zusätzliches Hinzufügen von Bässen mittels Equalizer, um sich dieses wohlige Kribbeln in der Magengegend zu verschaffen, beginnt der Rockster laut zu pumpen. Wer ein bisschen an den Reglern schraubt, kann damit also Klassik ebenso genießen wie Metal, Dubstep oder Rap.“

Fazit:

„Ob auf Partys oder Gartenfesten, für Vorträge oder den Bandproberaum und Konzerte - die Einsatzmöglichkeiten des Rockster sind ebenso vielfältig wie seine Anschlüsse.“

„… einiges zu bieten, was sich auch vom Klang behaupten lässt“
SFT 09|2015
„Trotz seiner  Größe  und  seiner  geradezu  brachialen Klangkraft  kann  man  den  als  Konzertspeaker deklarierten  Lautsprecher  auch  fernab  jeder Steckdose auf der Terrasse, im Park oder am Strand  betreiben  –  integriertem  Akku  mit maximal  sechs  Stunden  Laufzeit  und optional anschließbarer 12-Volt-Batterie sei Dank. Der Mobilität zu gute kommen auch einige äußere Faktoren am stabilen MDF-Gehäuse des Speakers.  Vier  Rollen  –  zwei  davon feststellbar – sorgen für einen sicheren Stand, zwei Griffe an den Seiten erleichtern  das  Ziehen  und  Schieben. 

Teufel hat  den  massiven  Riesenspeaker  allerdings für seine Größe nicht nur einzigartig mobil gebaut, sondern auch bei der integrierten Technik ganze Arbeit geleistet. So lassen sich zwei Geräte via Bluetooth  oder  Analog-Eingängen  simultan verbinden [...]. Ohne Unterbrechung  kann  zwischen  den  Quellen gewechselt  werden.  Außerdem  lässt  sich mit  angeschlossenem  Kopfhörer  ein  Lied vorhören,  während  ein  anderes  von  der zweiten Quelle abgespielt wird. Getrennte Pegelregler sorgen für die passende Klangabstimmung  je  nach  Musikrichtung.  Wer selbst für Unterhaltung sorgen will, bedient sich an den Anschlüssen für Gitarre und Mikrofon. Featureseitig hat der Rockster somit einiges zu bieten, was sich auch vom Klang behaupten lässt.
 
Wie man es von einem 32 Kilo schweren Lautsprecherkoloss erwartet, bringt der Rockster Leistung en masse: Bis zu 115 Dezibel laut spielt er [...].  Auch große  Outdoor-Partys  beschallt  man  damit mühelos.  Wirklich  erstaunlich  ist  aber,  dass die Wiedergabe selbst auf hoher Lautstärke stets klar bleibt – es sei denn, man möchte alle Grenzen sprengen und die Party zum Kochen bringen. Dann dreht man die Frequenzpegelregler bis zum Anschlag, woraufhin der Rockster Wände zum Beben bringt und Gitarrenriffs  erbarmungslos  Richtung  Zuhörer feuert.“

"...the ROCKSTER isn’t just loud, it’s also precise. No cheap technology is on offer here, but rather premium components that are able to master the entire signal path."
www.areadvd.de 04.08.2015
"The website assures us, "Wherever it rocks, the grass won’t grow.“ We’d just like to assure you that the ROCKSTER can do more than “rock”. It reveals itself to be a club on wheels, and the ROCKSTER plays techno/trance, house and R& B with such abandon that the first 666 buyers received free legal insurance from the company Arag as a free add-on -- something they can certainly make good use of.”

"It pushes out the pressure at levels that can be felt in the pit of one’s stomach. At the same time, it remains much more precise that many other PA systems. It throws the electronic effects far into the room and can be put to good use outdoors thanks to its power.”

"And when the tracks really get going, the ROCKSTER makes it clear that it’s the king of all portable sound systems. In comparison, what other modern boomboxes or larger BT loudspeakers bring forth is not much more than lukewarm air. These devices shouldn’t even try to compete with the ROCKSTER, no matter how many watts they claim to have. It’s as if a Dacia Logan would race against a Ferrari 488 GTB – best to not embarrass oneself trying.”

"Teufel has  [...] probably put together the best mobile speaker system that not only instils fear in the competition but plays them mercilessly against the wall. Calmly and even-temperedly, levels are attained that are so high, one always has to be careful not to get arrested for disturbing the peace.”

"Whether old-school rocker, party fan or digital DJ, the ROCKSTER is the ultimate tool for everyone who wants to have fun while listening to music. And the ROCKSTER isn’t just loud, it’s also precise. No cheap technology is on offer here, but rather premium components that are able to master the entire signal path. We also very much liked the robust professional finish enhanced by skilfully set modern accents.”

„Wir haben nachgemessen: Voll aufgedreht, erreicht der Rockster sogar etwas mehr als die höllischen 115 Dezibel Schalldruck, die Teufel verspricht. Zum Vergleich: Ein Presslufthammer kommt auf „nur“ 90 Dezibel [...].“

„Der Teufel-Lautsprecher ist nicht nur verdammt laut – er klingt dabei auch durchaus gefällig: Bässe kommen trocken und druckvoll, Mitten und Höhen präzise und ausgewogen.“
