Hello dear Nubert team: I've been the proud owner of a pair of NuWave 8s and the CS-4 center speaker in Neptune blue for about 14 months now, and it's a real wonder how you can get such a bass out of such cabinet sizes and, above all, such chassis sizes (diameter = 18 cm). Normally other speaker manufacturers would have to pack their bags! I had the chance to compare my Nubert loudspeakers directly with a pair of loudspeakers from a well-known manufacturer in the USA that cost around DM 10,000. This raised the question for me and some of my friends: why spend so much money when the cheaper speakers are clearly the better ones? The sound and the power of the bass that you get for just under 1800 DM is phenomenal! Even TV programs and music stations are properly enhanced. With really loud movie passages in Dolby Digital and DTS with my Yamaha DSP-A1, you could even work without a subwoofer, the NuWave 8s reach so deep down into the bass cellar. Even really powerful DTS bass attacks (U-571: Explosion of the water bombs, Sleepy Hollow: Horse ride through the forest) were handled without distortion. It seems as if the drivers simply don't want to reach their limits, even though they look more than dainty. Everyone, really everyone, asked about the subwoofer when listening to loud music and no one could believe that the NuWave 8 played without it. The bass is so good that I had to turn the bass control down from +5 (old speakers) to -2 and switch off the bass extension. The sound pressure that the speaker produces is also comparable with professional PA systems. Of course, this also applies to the center speaker. All in all, Nubert loudspeakers are as good as a gift for what they can do, for the materials used (other loudspeakers up to DM 5000 can only dream of such crossovers) and for the way they are finished. I recommend Nubert loudspeakers to EVERYONE without exception - why spend more money? For me, there is simply no better sound !!!

I am since about a week very proud owner of the aw550 subwoofer. and although I was initially somewhat skeptical of a subwoofer with almost twice the power to switch to this small, I was in no time taught better. my small room (17m2) is optimally sounded by the aw550! the bass comes precise, powerful and bring the floor to vibrate :-)i am absolutely satisfied with the subwoofer and do not even want to imagine what brute force there even a 850 or 900 must have - for my room probably too much of a good thing :-)greetings from austria (no kangaroohs),harry

Hello, Mr. Schiffler! Thank you for your constructive contribution. In principle, we also answer all questions. Mostly, however, directly by e-mail. Believe it or not, we had a forum created a long time ago. However, the topic was put on ice due to time constraints. However, I have also noticed the change in the entry structure and I think it is now really time to realize this project. Give us a little more time. It's coming...

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!
