In response to the discussion between Mr. Roderburg, Mr. Redlich and Mr. Schiffler, here is an attempt to clarify the problem: A loudspeaker designer has to deal with the fact that the room sometimes responds violently to what the loudspeaker tells him. In rooms with parallel, solid room boundary surfaces, a large number of natural resonances (room modes) occur in the low frequency range, which amplify the radiated sound. The resulting level increases are greater near the walls than in the center of the room, so that the listening position should be as far away from the walls as possible (there is a lot more to say about this). Since the living rooms of most potential customers (and probably also his own listening room) correspond to the above-mentioned boundary conditions, the developer will design the bass radiation of his speaker for this typical application and limit it sensibly. The reference to the subwoofer in the 660 does not apply here, as its volume cannot be adjusted at will, whereas in rooms with a lot of low-frequency absorption and non-parallel room boundary surfaces, the room modes will be much less pronounced: Low-frequency absorption is caused, for example, by so-called flexible facing shells (e.g. wood or plasterboard cladding, as is very likely the case with Roderburg's pitched roof). It can't be the carpet, because it hardly absorbs any low frequencies and it's probably not due to polarity reversal either, otherwise Mr. Roderburg wouldn't praise the 660 so highly. I had a lot of fun with the 660 for many years in my room, which was also highly damped. After switching to Nuwave 10 (even more precise), the additional active bass linearization module brought the final kick, so you, Mr. Roderburg, should be happy about your room, which offers you the opportunity to hear only what is really on the can (if you care to), although an upgrade with an active woofer is probably in order... Best regards, Manfred Werner!

To Martin R.: I have a room of about 24 square meters, wood paneling, carpeting throughout. Close to my subwoofer (factory outlet competitor from Berlin), the bass is quite decent, but as soon as I take three steps back into the room, the fat foundation disappears into thin air, whereas in the corners of the room, the bass is overwhelming. at the moment, it's still too much effort for me to move my confusingly wired equipment to another room, but I think it's due to the wood and all the carpet.

To Martin R. I beg your pardon!!! The specification was made on demand, with 0.8 Qm cone area per speaker, ha., ha..., now I'm holding the brochure I hear something ... in my hand, but it says 800 Qcm, i.e. 0.08 Qm x 2 = 0.16 Qm. He (the caller) must have hidden a few TT in his 660. He probably got the 800 Qcm wrong. So sorry for the mistake. But let's go back to the nuBox 660: the functions of the individual speakers are very precisely defined in Technik Satt. 2-way speaker with a sub-woofer (upper TT) and a lower TT that works purely as a subwoofer. So you already have 2 subwoofers in your room. A subwoofer that is supposed to provide audibly and perceptibly more pressure should have PA dimensions. If you really have enough power available, I still suspect a technical problem.

Hello Nubert team! After my first post, I browsed through the guestbook a little and came across numerous posts that contained questions which remained unanswered (at least in the guestbook). This may be due to the nature of a guestbook, which is not primarily intended for bilateral communication, but it is a great pity for the contributors concerned AND (future) customers with similar concerns.in my opinion, a forum would be a useful enrichment for this website.following the example of the popular UBB forums a la www.dasforum.de, www.areadvd.de or www.dvd.de, customers could exchange experiences with loudspeakers, home cinema etc. or talk about their favorite pizza here. Answers or comments from your employees would also be possible (and desirable), and I can also imagine a division into sub-forums such as subwoofers, home cinema, technology, etc. From a technical point of view, this shouldn't be too much of a problem, as I understand that there are ready-made forum frameworks that can be adapted to individual needs/topics. Could you imagine offering such a forum on your website or is such a concept not feasible due to a lack of admin staff, for example? Perhaps there is also an enthusiastic customer who would take on this task on a voluntary basis and check on things from time to time. greetings from the Rhein-Sieg district Jochen Schiffler

To Stefan R.: I don't know how you arrived at the cone area of 1.6 square meters. According to my calculations, I arrive at about 0.13 square meters or 1300 square centimeters. To get to one square meter alone, you would need 3 46cm speakers per speaker with 2 speakers. With 1.6 square meters, you would need 3 60 cm drivers per speaker. Such a speaker would certainly deliver bass without end, but I think you have miscalculated slightly. I'm going to save a bit more money and then buy a Nubert subwoofer because I don't want to spoil the sound quality of the 660s with a bad subwoofer. Does anyone know anything about the AW1000, AW2000 or AW4000? I read something in the guestbook and am very interested.

Hi everyone, I've owned the 660s for about a month now and I think they're the absolute bomb, whether it's Pink Floyd, Camel, folk, gothic, classical ... . Not a particularly informative article, but all the more enthusiastic. Greetings, Uwe

AW850: picked up, unpacked, set up, connected, switched on, calibrated, tried out, blown away! Wonderful... Thanks for building it!

Hello dear Nubert team, dear readers,I've been the proud owner of the 360 for several years now. I now use it as a monitor for mixing and recording in my own home studio. I had actually only bought it for hi-fi listening. But when I heard it for the first time at home, I immediately decided to try it out as a studio monitor. And what can I say? Since then I've only listened to the 360, the eternal search for reasonable (price/performance) and neutral (sound) monitors has come to an end. For me, there's simply nothing better, the hymns of praise really aren't exaggerated. Herbert Muhr

Dear Nubi Your speakers are mega cool. Could you give me some if possible the subwoofer nuWave AW-7. Thank you Nubi your speakers are the best. I love you.

'HAL! I also said that it could be because of my room. If the bass I hear is all that speakers costing 2,000 marks can deliver, then either I'm deaf or the bass response drops as the price goes up. I have tried to shift the blame from the speakers to the room: I listened to 2-way floorstanding speakers for 170 Marks each in a room with a tiled floor, no pitched roof and about 50 square meters. It was simply better than in my room. I could imagine that the speakers would sound better in a different room or produce more pressure in the bass range, but I have described MY experiences in MY room. If they could give me some tips, that wouldn't be bad either, but they have never listened to music in my room and therefore can't know how much (or how little) bass is in the air. -Martin Roderburg
