Reference 851 5.1 Sound System White incl. Cover Black
Breathtaking
NUMAN REFERENCE 851 COLLECTION
Don’t just come close to the perfect cinema experience, or even match it: outshine it completely. We had no other intention when we created the NUMAN Reference 851 Collection. The result can be seen and heard. The only thing missing is the popcorn. Everything else is acoustically provided by our side. More is not possible. Play the film.
Stylishly decent
THE SOUND-AESTHETE
The speakers of the Reference series are, as the name suggests, the reference when it comes to speaker technology at NUMAN. Carefully selected components and a sophisticated tuning make their sound image unique. Thanks to the classic design and a wide range of colours, they blend seamlessly into every living space.
All components of the NUMAN Reference 851 5.1 sound system are harmoniously matched and play their full potential, especially in the set, to create lively and realistic soundscapes.
The NUMAN Reference 801 stand speakers are characterised by a natural, pleasantly warm sound with a pinch of air and offer a high precision in the bass range without overloading the bass. Their balanced sound character is voluminous even at quieter sound levels.
The acoustic image of the NUMAN Reference 802 two-way shelf loudspeakers is characterised by a particularly neutral centre image and a breath of fresh air.
The NUMAN Reference 803 two-way centre speaker offers a fine, nuanced mid-range and high-frequency resolution with a frequency response specially adapted to speech intelligibility. The D'Appolito arrangement provides a particularly wide spatial resolution with broad radiation characteristics.
The NUMAN UniSUB active mono subwoofer enriches the setup with more depth and sound.

Preis Leistung Super, hat meine Erwartungen erfüllt. Sehr guter Kundendienst!
Great value for money, met my expectations. Very good customer service!
Saubere Verarbeitung, top Qualität
Clean processing, top quality
Das Numan 5.1 system ist spitze hier stimmt Preis-Leistung hat sich sehr gut ins Heimkino eingegliedert top empfehle es ohne bedenken weiter aber das hier liest hat denke ich mal Ahnung von der ganzen Materie
The Numan 5.1 system is great, the price-performance ratio is right here, it has been integrated very well into the home cinema, I recommend it without hesitation, but I think that reading here has an idea of the whole matter
Hab das Set seit nem halben Jahr aufgestellt. Ich bin kein HIFI Spezialist oder Audiophiler, kann aber sagen das es klanglich das beste ist, was ich je gehört habe. Ich glaube nicht das es für diesen Preis nennenswert bessere Systeme gibt und behaupte, das derjenige der dieses Set kauf und noch ein paar hundert Euro in Raumakkustik (Breitband und Bassabsorber) investiert, ein besseres Ergebnis erzielt als derjenige der das Vielfache für Lautsprecher ausgibt. Wer ausreichend Platz hat (die Lautsprecher sind groß und möchten auch etwas Wandabstand) kann hier getrost zugreifen. Wer gezwungen ist Platz zu sparen, könnte allerdings woanders glücklicher werden. Eine wandnahe Aufstellung mögen sämtliche dieser Lautsprecher nicht. (Selbst Center und Satelitten haben eine Bassreflexöffnung nach hinten)
I've had the set set up for a year and a half. I'm not a HIFI specialist or audiophile, but I can say that the sound is the best I've ever heard. I don't think there are significantly better systems for this price and I claim that those who buy this set and invest a few hundred euros in room acoustics (broadband and bass absorbers) will achieve a better result than those who spend many times more on loudspeakers. If you have enough space (the speakers are large and also want some distance from the wall), you can confidently access them here. However, if you are forced to save space, you could be happier elsewhere. None of these speakers like being placed close to a wall. (Even centers and satellites have a bass reflex opening to the rear)
Really excellent bang for your buck. For 800 euros, which is just slightly more expensive than most decent soundbars, I was not expecting this level of build quality and sound quality. Really excellent. The bass is really something else. If you're looking to upgrade your low-end 5.1 system but don't feel like spending an absurd amount on high-end audiophile gear, this is perfect. It gets you 75% of the way there for 10% of the price. Also I read many reviews on here saying the covers have issues with the magnets so I avoided them

Super sound. Perfekte Verarbeitung. Gute Lieferung.
Great sound. Perfect processing. Good delivery.
Ich habe mir die Lautsprecher für meine neue Küche gekauft. Die Lieferung erfolgte superschnell, die Ware war überdurchschnittlich gut verpackt. Die Qualität der Lautsprecher ist sehr ordentlich und die Klangqualität sehr gut. Der Raum in dem die Lautsprecher betrieben werden ist ca. 25qm groß, die Lautsprecher sind hierfür absolut ausreichen. Die Basswiedergabe ist satt, die Höhenwiedergabe kristallklar. Ich bemerke keinen unterschied zu meinen Harman Kardon Lautsprechern, die von den Abmessungen her ähnlich sind. Ich würde mir diese Lautsprecher sofort wieder kaufen. Das Preis Leistungsverhältnis ist unschlagbar. 5 Sterne!!!
I bought the speakers for my new kitchen. The delivery was super fast, the goods were well packaged. The quality of the speakers is very decent and the sound quality is very good. The room in which the loudspeakers are operated is approx. 25 square meters in size, the loudspeakers are absolutely sufficient for this. The bass reproduction is rich, the treble reproduction is crystal clear. I don't notice any difference to my Harman Kardon speakers, which are similar in size. I would buy these speakers again in a heartbeat. The price-performance ratio is unbeatable. 5 Stars!!!
Ich nutze diese Lautsprecher als Surround-Lautpsprecher in einem 5.1 System. Als andere Lautsprecher kommenNUMAN Octavox 703 - 2-Wege Centerlautsprecher Heimkino Hifi Lautsprecher Lautsprecherbox (150 Watt, tiefe kraftvolle Bässe und überragende Dynamik, designed und entwickelt in Berlin) weiß undNUMAN Retrospective 1978 - 3-Wege Lautsprecher Heimkino Hifi Lautsprecherboxen Paar (320 Watt, stilechte Retro-Boxen, designed und entwickelt in Berlin) weiß-braun zum Einsatz. Die Lautsprecher sind für den Einsatz vielleicht etwas überdimensioniert, verrichten Ihren Dienst jedoch zuverlässig und ich bin vollends zufrieden.
I use these speakers as surround speakers in a 5.1 system. The other speakers are NUMAN Octavox 703 - 2-way center speaker home cinema hi-fi speaker box (150 watts, deep powerful bass and outstanding dynamics, designed and developed in Berlin) white and NUMAN Retrospective 1978 - 3-way speaker home cinema hi-fi speaker boxes pair (320 watts, stylish Retro boxes, designed and developed in Berlin) white-brown. The speakers are perhaps a bit oversized for the job, but they do their job reliably and I'm completely satisfied.
Die Boxen waren eigentlich ein völlig spontaner Kauf nur der Optik wegen. Ich besitze einen schönen alten und komplett aufgearbeiteten silberfarbenen AKAI Receiver der wieder zum Leben erweckt werden sollte. Der Preis schien auch in Ordnung und so bestellte ich die NUMAN Octavvox 702. Eigentlich bin ich nur ein Laie aber im Vergleich mit meinen auch sehr guten Yamaha Boxen staunte nicht schlecht was ich hier zu hören und zu sehen bekam. - tolle Verpackung - tolle Verarbeitung - toller Preis - sehr guter Raumklang Jetzt möchte ich ja am liebsten die nächst höhere Qualitäts- und Leistungsklasse Klasse des Hersteller ausprobieren.
The boxes were actually a completely spontaneous purchase just because of the look. I have a beautiful old and completely refurbished silver AKAI receiver that should be brought back to life. The price seemed right too, so I ordered the NUMAN Octavvox 702. I'm actually just a layman, but compared to my Yamaha speakers, which are also very good, I was amazed at what I heard and saw here. - great packaging - great workmanship - great price - very good surround sound Now I would like to try the next higher quality and performance class from the manufacturer.

Ho acquistato questo kit in sostituzione all' Explorer 5.0 Eltax preso da Tech & Sound System. Mi sono sempre trovata bene e il design richiama molto il kit Numan Reference 851, per questo l'ho scelto.
Il suono è potente e chiaro, adatto sia per ascoltare la musica che film.
Il design classico e nero si è adattato perfettamente nel mio soggiorno, ricreando un ambiente sonoro avvolgente.
I purchased this kit to replace the Explorer 5.0 Eltax from Tech & Sound System. I've always been happy with it and the design is very reminiscent of the Numan Reference 851 kit, which is why I chose it. The sound is powerful and clear, suitable for both listening to music and movies. The classic black design fit perfectly into my living room, creating an enveloping sound environment.
