Tief Tiefer NUBERT That's all I can say about the AW - 900.

hello dear Nubert team! i was looking for rear speakers and an active subwoofer so that i can enjoy the full functionality of my dvd player. I didn't want any help from magazines this time. We want to make good use of the new medium (Internet). I found a list of loudspeaker manufacturers at http://www.yahoo.de/. Nubert ... the name was already familiar to me. And after one click, I ended up here and am totally thrilled. I am impressed by the technical variety and also by the price information. You rarely see prices on manufacturers' websites. I no longer need to search any further. I have found what I was looking for! Thank you very much, Nubert!

I received the pair of Nubox 390s today and I am simply thrilled. Clear sound with incredible depth. At first I thought that since my Denon integrated amplifier can't adjust the bass or treble range, I'd have to get something like the Musical Fidelity X-Tone to adjust it. But now: no need, the sound is perfect!

Hello Martin, I would like to take this opportunity to thank you and Günther Nubert for the excellent fitting of the speakers for the Jeep. It's just brilliant how the speakers sound. The car already stands out, but the sound is even more stunning. Therefore, MANY THANKS!!!!!

Best regards from the topic fux 'Home Cinema' Hans

Thank you very much for your fax reply of 02.06.00 and for sending me the latest measurement results of the Nuform 90 with ABL-F-90 equalizer module, which I was able to interpret correctly. Unfortunately, I am only able to reply to you today, as I was at home in Germany. There I also had the opportunity to test the equalizer module that you promptly supplied. First of all, I can confirm that the Nuform 90 has significantly improved its dry bass reproduction by looping in the equalizer. I operate the speakers with wall spacing and a standard power amplifier (Rotel) with 150 W sine wave power, which is completely sufficient for a 35 square meter living room. Of course, you need the program material with the appropriate bass content. As an avid lover of classical music, I appreciate powerful kettledrum sounds, which I have now been able to experience in a completely new way. But good jazz recordings also sound fantastic; in my opinion, the spatialization of this musical genre has improved considerably. May I also take this opportunity to thank you for the really first-class and patient advice from your employees Siegle and Bühler. Thank you once again for your efforts. I remain a satisfied customer Yours sincerely W. Schucht

Reply to Mr. Becker's entry of 29.5.2000. (STRONGLY SHARPENED VERSION) Dear H. Becker, you wrote that you were interested in the nuBox 360. Since you found out that its crossover is very complex, you no longer know whether it is worth listening to! You can only find that out IF YOU ACTUALLY LISTEN TO THEM. On pages 26 and 27 of our Technik Satt booklet you will find (in my opinion) quite impressive answers to the complexity of crossovers. The question of what constitutes good sound is not always easy to judge by ear. Nevertheless, the results are easily reproducible if the jury is experienced, well rested and critical. Your statement that every component distorts the sound is very strange. You could just as well say: every wheel increases the rolling resistance. - Who would think of changing from a bicycle to a ONE-WHEEL in order to reduce the rolling resistance?--When updating the nuBox 360/4 to 360/5, we proceeded as follows: experienced sound engineers evaluate speakers in elaborate listening tests (including various crossovers), and only then do we decide which model to build. - Sometimes, improvements that are clearly measurable do not result in a gain in sound quality. - In this case, the update is not carried out - in the case of the 360, we have driven 13 variants to (possible) absolute perfection - although no speaker with a 6 dB crossover has ever won, we are continuing to develop this type of crossover (in conjunction with all-pass filters). Order of the test:--PLACE 1: DSP active speaker with delay in the treble channel and 17 additional equalization filters --PLACE 2: NUBOX 360 Current production version with an additional 8 components. --PLACE 3: (only very close behind) NUBOX 360 current series stand--PLACE 11: 360 m. Filter slope 6 dB and reverse polarity tweeter without tweeter delay. ---- The time alignment only plays a subordinate role - Why do the 6 dB crossovers have a clearly audible effect on the sound? Stronger tweeter resonance and more distortion! The theoretical advantage of 6 dB crossovers (zero group delay, therefore perfect square wave signal with in-phase sum of the electrical signal) is dramatically worsened by inserting the speaker chassis into the chain. - Because loudspeakers with 6 dB crossovers have to be operated with the polarity of the tweeter reversed, the original cleanliness of the electrical signal is also reversed. --You can read about the step response of the nuBox 360 in the Stereo 9/99 review. It may not be perfect in terms of time response, but it is still better than most of the other speakers in the same test, which cost up to 8 times as much. The fact that time alignment has any influence on the sound is highly controversial. Most benchmark experts claim: indistinguishable. In my own listening tests, the correction of group delay (with DSP systems) was just about distinguishable. With kind regards GN.

And once again I have to take my hat off to the Nubert team! Since my DVD player arrived (Yamaha DVD-S795 - also ordered from Nubert, where else? :o)) my 5 NuBoxes (4xnuBox 360 and CS2) have been very happy! If you turn off the subwoofer, you can't believe the incredible dynamics of the 360s. Even movies like Volcano, which actually work a lot with LFE, come across quite effectively! I can only marvel that such 'small' speakers can come close to reproducing the sound of 'full-blown' floorstanding speakers...and if you read Stereoplay, you'll be surprised why the nubox 360 was even able to place itself ahead of a pair of DM 2300 speakers from a renowned loudspeaker manufacturer, but once you've listened to it, it quickly becomes clear why! What's more, at 600 DM/pair, the nubox 360 is anything but expensive. In terms of performance, you could call it a miracle! In any case, the AW-900 will soon follow for a listening test and may even find a permanent place in my home! Nubert fulfills four wishes at once - the wish for competent service - the wish for quality - the wish for a low price - and the wish not to be ripped off! All this speaks for Nubert! And that's another reason why I personally have made the Nobert Speaker Factory my hi-fi supplier! Because Nubert doesn't offer anything that doesn't work! Here, performance is given top priority in order to satisfy (almost) every visitor/new customer/customer! THAT deserves the highest recognition! Respect and hats off to the team!

To the Nubert team, I have been a good Nubert customer for many years. I own the 460, 360, CS3 and AW 900 and have been impressed by the sound and level. But what I miss are the frequency responses that should be on every speaker in the Nubert brochure. It would be really great if you could see the curves in the future.

Hello Nubert team, more than three years ago I was looking for new speakers. I (naturally) came across the 360s in the STEREOPLAY test review. After the info package arrived, I decided that it would be better to invest an extra 200 DM in volume instead of stands. Two weeks later my 390s arrived. The neutrality and the creamy bass made me grin constantly while listening to music. Since May 15, 2000, however, the grin is gone. That's when my new AW-850 arrived. I actually had reservations about buying it, as the bass of the 390 is already quite deep. Now I just listen to my music with my mouth open. How could I live without a (very good) subwoofer? Whether Mahler or Massive Attack, everything is better. However, it took me a good three days to find a sensible set-up and adjustment. I let the 390s run at full power, as they are not weak satellites. The result: when I move around the room, the quality of the bass changes much less than without the 850s. Even the booming in the corners of the room has disappeared. Incidentally, the most commonly recommended set-up with the SW between the main speakers led to disastrous results. Total boominess around 43Hz followed by a -20dB hole from 50Hz to 80Hz. Unbearable but understandable: the room modes parallel to the stereo base are hardly excited, while those perpendicular to the stereo base are strongly excited by the fact that my speakers are only 0.5m in front of the wall. That's why the 850s are now positioned in such a way that they excite the room where the 390s don't and vice versa. When I'm sitting in the normal listening triangle with the main speakers, it's against the wall to my left, with the back about 40 cm away from it. Volume at -3dB, frequency control in the middle and phase approx. 30 degrees. Oh yes, I wouldn't have been happy with a simple 0/180 degree switch. Best regards, Matthias Ciupka
