Guestbook

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.

@Warranty period now 2 years

I think it's a great pity that nubert is reducing the warranty period from 5 to 2 years.
Even the pro-arguments you cite are of no use to me. I can't really understand them. Until now I actually believed that my 5 nuberts-LS were so good that nubert could offer a 5-year warranty. Now I no longer believe that.

Yamaha proves that there is another way. They are extending the warranty on their current Aventage AV receivers from 2 to 3 years.

Regardless of whether I would have "needed" 5 years or not. Unfortunately, there's one less reason for me to buy nuberts from now on.

Hello dear Nubert team!
Since I think that many interested music lovers first look around here in the guestbook, I would like to disclose my last step here again.
I started with the nuBox 381, which is really good for the price I paid.
Next step: nuVero 4, a speaker that made some people wonder about the excellent price-performance ratio. Often you don't really need more "box". It would be better to consider replacing the upstream components.
Once I had done this, I was in the mood for even more.
The nuVero 14 came into consideration for me.
And now that I have it in my home, I'm happy.
I have now achieved my goal.
You can test all the speakers at home at your leisure. And if it's really not acceptable for you, you can exhaust all the possibilities.
Although my listening room is certainly not 100% optimal, I am very, very satisfied with these towers. In my opinion, you can't get more for the money.
So a big thank you to the Nubert team.
A very satisfied customer ....... 😂

Dear Nubert team,

I have been a customer of your company for many years now, whether NuWaves, NuLines or NuVeros, all the products I have purchased have always been an extension of my listening experience.

The service provided by your company (e.g. listening to loudspeakers on components I brought with me to the listening studio) and especially the after-sales service deserve special praise.

It so happened that I had a problem with my 4 NuVero14. While listening to a live recording, all 4 tweeters cut out after a feedback loop. I couldn't explain this, I could rule out clipping due to the power reserves of the amplifiers (2 x Primare A32 on a Primare Pre30), the volume was "only" room loud. Overloading the crossovers was also out of the question for me.

Good advice was expensive, so I first called the service hotline. As all the staff were on the line, they promised to call me back immediately. It took less than 5 minutes and I was able to describe my problem. After a bit of "shop talk" and discussing several options (they even offered to send me new boxes to return the speakers - free of charge, of course!!!), we decided on the experimental solution (i.e. I had 4 new tweeters on site within 3 working days for me to install and test myself, and that too: free of charge).

What can I say? Now the new tweeters have acclimatized and settled in, everything is great again. This is customer service at its best. Many other companies in Germany should take a leaf out of their book.

All I can say is: perfect service all round!!! Thank you!!!

Many greetings to the whole team!!!

Proud owner of a dream surround system for 3 days now.
4 x nuLine 264
1 x nuLine CS-174
1 x nuLine AW-1100

It took me 6 hours to set up before I could enjoy the sound. I can say: it was worth every drop of sweat!

Nothing has been calibrated yet and everything is only aligned to my listening position, but nevertheless ....... an impressive sound. Crystal clear, with plenty of steam behind it if desired.

I can't get enough of listening. My references for the test were:
-Mozart's Requiem (digitally reworked version)
-Subway to Sally - Best of: Dress of Roses
-Within Temptation - Mother Earth
-various bands and music genres from Youtube

My result: speakers to fall in love with. They are REALLY honest. They point out mistakes, but their brilliance doesn't make them sound worse. On the contrary, you suddenly learn that even singers in a studio are only human. Good recordings, on the other hand, make them sound more than just perfect. It can be said without hesitation that these speakers elevate the listening experience to a new level.
