Regarding Mr. B. Buchert's comment: Somewhere I have read this exact wording before... where was it? Yes, now I know! It was in the Orbid-Sound catalog in the Hifi-Boxes-Practice section. The first sentence is practically copied (also the following sentences). OK, Orbid-Sound builds speakers with a very good sound ... but for me it is also crucial that both Nubert and Orbid-Sound do not have exorbitant prices for speakers. Therefore😂direct sales to the front An acquaintance of mine owns Nubert speakers and is very enthusiastic about these speakers (both in terms of sound and price). I, however, have so far preferred the Orbids (probably a war of faith). But I don't believe !!! that the impedance curve has no effect on the sonic impression. I also find the fact that everyone is pouncing on the frequency curves a bit strange, but as someone in the guestbook put it very correctly: the main thing is that the speakers sound good! Then I don't care about the theory.

Concerning Benedikt Buchert's entry and G. Nubert's reaction I find it 1. very impressive that a 15-year-old is so extensively involved in physics, even if he misunderstands or misinterprets a lot of things, but to express his opinion eloquently is quite something. And secondly, I find it impressive that Mr. Nubert goes into such detail about Benedikt's entry.it looks as if Benedikt has taken a large part of his comments from some online publication,perhaps this has also put him on the wrong track? Physics or not: if a speaker sounds really good to me subjectively, as an end user I simply don't care what the impedance or frequency response curve looks like. The fact that these curves look very good on Nubert speakers can only make me happy, even if I ultimately don't care.

Hello, I left a comment some time ago. In it I wrote, among other things, that I bought the Nubox 300 and was absolutely happy with it on my Luxman amplifier. The emphasis is on WAR ! I have now built myself a tube pre- and power amplifier with a frequency range of 10 - 44000 Hz. It's hard to describe what you can now hear from these speakers. I am absolutely blown away, I have never regretted the purchase and can only say once again that I will not buy any other speakers than Nubert speakers. This may sound like false advertising to some, but it really is the case, and I have made a few comparisons with other speakers such as Heco, Wega and others, and I always come back to Nubert! I can only recommend these speakers. I am always ready to answer questions!

Hello! i have just seen a picture of the AW-7 on the news page. what color is it? it looks like metallic blue. It would be a rattling hot color!!! you should offer it, at least normal blue, glossy! Many greetings and thanks for building the NuWave 10, I look forward to listening to music every day after work!

Hello Nubert team, it's a pity that there are still people who don't know what a guestbook is. Dear people out there, if you have specific questions, please send them to the normal Nubert e-mail address. Yours sincerely, D. Wagner

Response to the guestbook entry by Benedikt Buchert: Dear Mr. Buchert, thank you very much for wanting to give me some extra tuition in measurement technology. - I spontaneously imagined that I was a cab driver in his 27th year of work and finally a passenger had the mercy to explain to me the amazing function of the steering wheel and accelerator pedal! With your entry in the guestbook you have already proven that you had access to our web-page - it would have been very easy for you to have a look at our information in the Technology Special section and (if you are really interested in technical contexts) then to examine the data sheets and Nubert boxes as downloads for information that is useful for you. I find it inappropriate to first express your opinion in a public forum and THEN seek information. - It is also not entirely clear to me what your post in a guestbook is supposed to achieve; an e-mail inquiry or a call to our call center would have been much more logical. Perhaps you are proud of the fact that you already know quite a lot about measurement technology at the age of 15 - but you can't seriously assume that you have to explain such simple things to an old hand! In our technology pages, we describe all the points you mention in your article in great detail. However, some of your questions are not particularly logical, because the letters MLSSA next to the diagram alone already define the question about the level recorder and the test signal, and the dB scale is given. The fact that the impedance curve says more about the quality of a speaker system than the frequency response is simply nonsense. As long as the nominal impedance is not undercut by more than 20 %, it's OK - if you have a good amplifier, it makes no difference to the sound what this curve looks like. Even with long cables or tube amplifiers, an extreme increase in impedance to over 100 ohms results in a difference in level of perhaps 0.5 dB at the corresponding frequency, which is at the limit of perceptibility. Greetings Günther Nubert

Hello Mr. Nubert! Today I would like to say something about your speaker catalog in which you emphasize the harmony of the individual transducers with the uniform frequency curves of your speakers. the discussion about the frequency curve, which almost everyone examines with sincere interest, must begin with a statement that will probably amaze you: -------------------------- THE FREQUENCY CURVE OF A SPEAKER, IT DOESN'T EXIST!!! -------------------------- Not a single loudspeaker in the world has ONE frequency curve. There are an infinite number of different curves for each speaker! The whole thing has to do with the fact that an incredible number of factors come together when creating such a curve. As every lottery player knows, this leads to an astronomically high number of possible diagram runs. Here are just a few factors that can have an extreme influence on the shape of the curve: = = = = = = = = = = = = = = = = 1. type of level recorder 2. make of measuring microphone 3. sensitivity setting on the measuring recorder (50db or 25db) 4. test signal (sliding sine, filtered noise or frequency sweep) 5. writing speed of the measuring device 6. paper speed of the measuring device 7. nature of the room (size, frequency-dependent ripple) 8. - - - - - - - - - - - - - - - In order to at least limit the serious (but completely practical) spatial influences, a DIN guideline in the 1950s stipulated that frequency measurements should be carried out wherever possible (preferably at a distance of 1m). The small measurement distance at least makes room influences less significant, especially if the curves are calculated in a so-called anechoic room. But does this really help? Music lovers don't normally live in an anechoic chamber - so the room influences are there again at home! As a result, in no single case does a loudspeaker sound as the DIN curve would have you believe. -- Finally, I would like to say that I don't think your speaker company is bad because of this little thing. I realize that they are one of the good manufacturers of transducers, but when you see that they advertise with their frequency curves, you wonder, since they are professionals. They of all people should know this. why do they try impedance curves in their next catalog? They say much more about the quality of a speaker system. Besides, ONE speaker only has ONE impedance curve, which makes the whole thing much simpler and more credible. Kind regards Benedikt Buchert ICQ: 131625275 P.S.: If you find any spelling mistakes you can keep them.

Hi, I'm still in the presales phase and was looking for information about Nubert speakers on the Internet (good site!) and in this guestbook. As I wanted to clarify some details about the set-up and also do a listening test (after all, these are loudspeakers :-) I went to Schwäbisch-Gmünd. In short: great service, a quiet listening room for testing etc. But then two problems: 1. the combination of nuWave-3, RS-5, CS-4 and Line AW-550 means that the only speaker at risk (all the others stand at 1.4m and higher and have a perforated metal cover) has to make do with a fabric cover (I'm only saying 2 cats out of 8 weeks :-) Ask the consultant: nothing possible. Inquiry to the hotline: Nothing possible. Directly from the manufacturer ... The alternative AW-7 is one size too big and also 50% more expensive. 2. the CS-4 is almost as big as the AW-550, but there is no alternative in sight, although the nuWave surround page also suggests 5xRS-5 - so why not 3x nuWave-3? The magnetic shielding, of course, but the RS-5 should have the same problem, so keep your distance? I'll keep looking around (Teufel, Bose et al.) until this is clarified, who knows, maybe there will be a Nubert set after all!

so it seems that i'm one of the few customers of Nubert who isn't RESTLESSLY ENJOYED by the products, but quite satisfied. i've had the nubox 360 for about a year (it would have cost 5 times as much years ago???), the cs-3, the rs-3 dipoles and recently the aw-7 sub. in view of the fact that the discount law has now been abolished (but was already in force before), there are now a lot of speakers like the 360 that can compete with it in terms of sound, or even sound better, especially b&w speakers should be mentioned here. not to forget the dimensions of the nubox 360, which are quite large. but canton and infinity should also be mentioned here, so the price is no longer the argument in favor of nubert. the teufel company should not be underestimated either, as i have read in many very positive reports. the workmanship of the nubert speakers is top, no question, they seem to have lost that little bit of sonic advantage over the competition at the same price.what also annoyed me a bit were the included cables, although i had ordered some anyway.the aw-7 is almost too much of a good thing for my rather small room, about 17 square meters, despite very good adjustment possibilities.so always compare before buying and try out as much as possible!!!! I know it's easier said than done, I felt the same way.

Hello Nubert team! This is the second part of my report from Sept. 11, 2001. Now I would like to say something about the magic box ABL-10. I'm glad that I didn't buy a subwoofer for my stereo purposes. The module elicits a great low bass from my nuLine10 that is never boomy or even annoying. The fantastic mid and high frequencies, as well as the resolution and spatiality do not suffer in any way. However, the module should be connected via the REC-OUT connection so that all music sources can benefit from the box. But then you will need two additional cinch cables (included). I personally chose a higher quality cable, but that's up to you. When I tried to achieve the same result via the bass control of my Accuphase E 211 amplifier, I failed miserably! I have noticed that relatively little has been reported about the ABL modules in conjunction with transducers and nothing at all in conjunction with headphones. I connected my Musical Fidelity headphone amplifier to the REC-OUT. Since it has a high-quality output, I connected the module there. This means I don't have to do without connecting my headphone amplifier (I can't even imagine). The headphone output of the amplifier could by no means keep up with the headphone amplifier (tube). However, I have to say that I listen to music that requires more resolution through my Musical Fidelity and a pair of Grado headphones, which I can recommend. I listen to harder music via the Accuphase headphone output in conjunction with the Beyerdynamik DT 931, which is very powerful. Great !!! So it's not just the transducers that benefit from the modules, but also the headphone outputs. I for one am thrilled and my wife is delighted that she has been spared the buckets of food in the living room. Best regards to all music lovers and to the Nubert team.
