Guestbook

I bought the Nubert NuBox DS301 to go with my old Philips floorstanding speakers and my XTZ subwoofer.
And I'm really impressed!
Although I'm sitting with my sofa right up against the wall, I feel like I'm right in the middle of a movie like Star Trek Into Darkness.
I wouldn't have expected this result!
I would also like to emphasize the really great design and the super workmanship of the boxes.
The shipping time was also great. I ordered and paid on Sunday and everything arrived on Tuesday. TOP!!!

The only negative point I have to mention is the dipole switch, which unfortunately is impractical when wall-mounted and has to be changed by dismantling the speakers.
Too bad, I think maybe a better or more practical solution could be found in the future?

Otherwise I'm completely satisfied, thanks for the great speakers, they expand my system and my listening horizon!

Yours sincerely

🙂 I ordered two Nubert Pro A 20 speakers almost a year ago. Of course, this improved the sound of my Loewe TV considerably. Unfortunately, after a few weeks, very strong humming noises occurred sporadically - and only for a few seconds at a time. After sending the Pro A 20 to Nubert, I was immediately sent new speakers. However, the humming noises then reappeared. The Nubert customer service team - who are excellent to deal with, by the way - assured me that an intensive test had yielded no results, but also asked me whether there was an amateur radio operator in my area. This is the case. I was then sent new, shielded speaker cables (nuCable Audio 8) - free of charge for the time being! After about 6 weeks of operation, I can say that there is no more interference. What's more, the sound has improved considerably thanks to a slightly different speaker set-up and certainly also thanks to the nuCable Audio 8. The Pro A 20 sounds gigantic! Speech intelligibility is very good. The sound when playing music DVDs is better than with my high-quality stereo system (Rotel plus A.. speakers). I would like to thank Nubert and especially my "personal Nubert consultant", Mr. Bühler!

Conclusion: Nubert not only supplies excellent loudspeakers, but also offers exceptional service: always available immediately via a free hotline; competent, very committed and super fast. And that in the service desert that is Germany!

I have been working in marketing and sales for 12 years. Initially 6 years in the direct support of customers, in the last 6 years I have worked my way up to the position of a member of the supervisory board of an international company with more than 1 billion ? turnover. Due to the variety of tasks that I have been given, I have had to deal with countless different company and market strategies.

I have been your loyal customer for 7 years now, my NuLine 102 and ATM deliver more than you promise; just yesterday I ordered 3 more speakers for 1700. No euro is too good for me. I can only praise you with my expertise: you sell excellent products and your customer service is top-notch. As a marketing and sales professional, I feel I am in perfect hands with you as a customer and product user.

Keep up the good work!

We ordered a pair of nubox 481s on Monday morning this week and they were on our doorstep by Tuesday lunchtime! A big compliment, delivery is not even that fast and uncomplicated with the giant retail octopus with the small a. in the company name! Unpacked, unplugged the old speakers (from ACR, a Swiss manufacturer that used to make home stereo systems rather than car hi-fi systems in the 1990s), plugged in the new nuboxes, great. We listen to a wide variety of music, often on vinyl, we are not sound purists or hi-fi fetishists, and my wife sometimes puts on loud, scratchy and rumbling old records. From almost perfectly produced electronic and 1960s beat music to fairytale or classical records, everything is included. However, the wonderful, balanced, clear and voluminous sound of the nubox 481 is particularly evident in the "good recordings" that Günther Nubert mentioned in his "thank you letter" enclosed with the speakers. We are very satisfied with everything and can warmly recommend Nubert! We thank you, Mr. Nubert, and congratulate you on your company, which offers such high-quality goods for a good price!

I have been the proud owner of 2 511 Nuboxes + cs-411 (aw-443 + DS-301 are on the way) for 1 week. What can I say, they are simply wonderful LS! Both visually and in terms of sound. Last night I just sat on the couch and listened to my favorite album in stereo. I didn't notice how time passed. That's how deeply the LS "sucked me in" 😂
My Berlin LS stood off to the side in the corner and were mightily "ashamed"!
It's been a long time since I've been happy to come home and just listen to music. Over the course of the week, the rest of the 5.1 system will arrive and I'm sure...NO convinced that this result will also blow me away! Thank you Nubert for broadening my horizons! 😬

I have replaced my existing 2.1 nuBox system with the new nuLines 264. However, the first listening impression was sobering ? little bass, overall very flat sound.

But thanks to the great Nubert hotline, the amplifier was quickly identified as the bottleneck, as it simply didn't have enough power. This shortcoming could be remedied by using the bi-amping mode with double speaker cabling (at least temporarily) and lo and behold: after a short break-in period, I was able to enjoy an outstanding sound.

The naturalness with which the dainty speaker reproduces even the deepest bass without losing transparency, especially in the mid and high frequencies, is always impressive. I never missed the old AW-441 subwoofer from my 2.1 system, quite the opposite ? the small bass bases are incredibly fast and produce a very precise kick bass that is always a pleasure to listen to. The speakers are mercilessly honest: bad recordings are therefore "inaudible" and no fun, while precise recordings with great dynamics lead to a completely new listening experience. This makes listening to music fun!

Dear Nubert Team,

I've had my NuVero 14 for over two years now and they play just great.
You no longer notice that the music is coming from two speakers, it's simply there, precise, big and incredibly present.
But that's not the only reason I'm writing this feedback, you know that yourself anyway :-)

The only thing I can tell the other readers about the NuVero 14 is that they like powerful amplifiers. The sine wave power doesn't matter, from 1...2
watts, the speakers already make 'a lot' of music, but it should be low impedance. My previous Marantz PM-16 (2*150W, damping factor 160 and also
not a lame duck) ran out of steam. It was already good, but with my Musical Fidelity M6-500i (2*500W,
damping factor >250) it sounds much better, although of course I'm not even close to the 2*500W.
It would be interesting to know whether modern, cheaper class-D amplifiers with a high damping factor are similarly good.
I don't know, the M6-500i is an old fashioned class AB monster, big, lead heavy and quite expensive.

Now to the actual topic :
I've just bought a NuVero AW-13 subwoofer to combat the infamous 30Hz resonance that even my usually trimmed
living room has. Since the woofers generate a mono signal from the stereo input signal, I initially
I initially only bought this AW-13, not another (e.g. AW-12) as a slave. My listening position is in the corner of the room, so I wanted to try it this way first.

Conclusion: Yes, it works! The AW-13 is now in the corner where I listen to music, parallel to the back wall of the room. It receives its signal from a two-channel 'preamp-out' connection on my amplifier. After the necessary adjustment of the
signal processor (invert signal, delay to 4.60m room length, low-pass 4-pole 60Hz) I only had to adjust the attenuation
attenuation and the resonance was gone.
It's not quite perfect in the other corner of the room because I didn't need the slave woofer, but that's not a problem for me.
not a problem for me, and if it becomes one, I can put an AW-12 there.
At 50 Hz I now have a bit more level in the room, but it's not booming, it's actually enriching. I have no
idea whether the 50 Hz level is more true or false because I don't have any equipment to measure it. I only have sine tones on CD, all at full level, and my ears, whose 'characteristic curve' I don't know. That's quite enough to adjust the AW-13, but of course not to measure the room characteristic.

In any case, I am very satisfied with the result and can therefore also recommend a one-woofer solution if it is
not have to be perfect in every part of the room.

Now one last insight from my private research, here on the subject of speaker cables:
I wanted to replace my old 2*4qmm twin strands because they were oxidized and ugly after many years. I had access to 1.5qmm highly stranded cable material with thin Teflon insulation. From this I made cables with 2*5 conductors each, i.e. 2*7.5qmm. I mixed the forward and return conductors together and bundled them close together so that the inductance of the cable is lower than with a twin strand. You achieve a slightly more powerful treble, but the effort is not absolutely necessary. The additional cross-section is a luxury that
you don't hear, nothing has changed in the bass.

Best regards
Stefan

I would like to thank the entire Nubi team, very detailed advice. Extremely fast shipping, on a par with the likes of Amazon. (Ordered on Sunday evening - the package arrived at noon on Tuesday)

About the speakers;
flawless workmanship and, for me personally, a very balanced sound that also knows when to go low.
(nuBox 311 ivm cs411)

I'm very satisfied all round and I'm almost afraid I'll become a Nubi addict :redface:

Hello Dear Nubert Team....

I received my long-awaited Nupros A-20 today and put them into operation and tested them via USB and analog ports. I played a lot from ACDC to Dire Straits, Santana to Led Zeppelin...... must say I was flattened and had to sit down deep in my office chair. The sound and bandwidth that comes across is tremendous...and the resolution of the compact speakers...simply unbelievable!!!! I heard instruments that I didn't know were used in the recordings!
I can recommend these speakers absolutely unreservedly......I will 100% not make use of my right to return them because I don't like them!!!!!!

Happy 😱 😉 :p :p :p :p :p

Hi Nubert Team,
I'm pleased to read in the new NUsletter that the new NuPros still come with a 5-year warranty.
The downgrade of your active systems to 2 years is a pity - as that was the reason for many people (including me) to buy them.

I was in possession of the first series and am now looking forward to the new edition. Finally with all the functions you could wish for.

But this time I'll be picking up the pair in person.
