Speaker B & W CM 9

The new cm, you get 9 B & W plenty Nautilus technology in a very noble housing for comparatively fair 2500 euro. Sounds suspiciously like a bargain. The exclusive test.

  2. Data sheet

At B & W, allowing love to ask. Although the English long the undisputed number 1 in the sophisticated design of the loudspeakers are so perfectly expanded around the world, although their development department in Steyning has now grown to over 20 men, and although the distribution channels are like never before, they do not change their product philosophy simply. It remains cautious and introduces new models or even whole lines only after long development and testing time. We had to wait six, on the new 800 series (with diamond tweeter) seven years on the new 600 types. And the 700 series of 2002 will probably even no successor.
They don’t have to. Because the classic B & W speakers to technically came along some music lovers, the British had 1 and 7 CM since 2006 with the CM two visually simpler, but more refined lifestyle alternatives in the program. The two were phonetically somewhat gentler not voted off – what the testers, stereoplay readers but very much appreciated: Reader election, they were always elected on the front ranks.
These CM models will be the CM Centre 2 now by the compact box of 5 CM, and the magnificent stand box CM 9 extended. “And thus”, rumors whispered in B & W, “is the price comparable 700 line redundant.” But yet here you go only if she has much more to offer.
Now, at least visually and haptically convinced the CM 9 all along the line. The high-gloss (there are in addition to the black even the execution of walnut and Wenge) is of fine quality, and the rather delicate appearance brings it on at least 26.6 kilo – a note on their robust construction. This is typical B & W:, after all, the British give up also on the CM models of ten years transferable warranty.
Technically, the developers have also operated a remarkable effort. Especially the 6.5-inch midrange driver with B & W typical Kevlar membrane catches the eye of the Viewer. This dream-midrange, which ensures the finest centers in almost all models of the Nautilus series, is for the first time to have boxes for something more than 2000 euros. His distinguishing feature: He works to avoid resonances, virtually without beading. Because without flexible clamping, the possible stroke is very low, his bass skills despite the imposing size of 17 cm are severely restricted. Two long-throw bass with membranes made of a Kevlar paper mix are used below 350 Hertz. The upper working range of the mid-bass ends at almost 4000 Hz; Here is the best aluminium dome. The flanged tube, also the ur-Nautilus borrowed, avoids short reflections of the sound radiated backward and attenuation also the natural resonance of the tweeter over the length of the tube.
And even on the crossover, Nautilus is found almost everywhere: “Flat” 6 DB filters and top capacitors from the German noble supplier Mundorf – this reads like a description of 800.
But what makes the CM 9 with these many Nautilus bonds? First of all, a pretty good figure in the measuring laboratory. The efficiency of 84.5 decibels is indeed not just record and requires powerful amplifiers of “more than 100 watts per channel”-League. But the band width from 30 to over 40000 Hertz is already all honor worth – as well as the low-distortion almost over the entire (not smooth) frequency response.
In the hearing room then the CM 9 remembered only once strongly the basic virtues of boxing testing: play, play a, play a and – equally important – make the speaker exactly horizontal and then firmly tighten the studs (here in the base). Of course I could not curb my curiosity and had the B & W after unpacking right “quickly” and have heard.
But so that you can’t get a CM 9. She sounded at the same time matt and gruffly. But with the precise adjustment of the spikes, she lost a part of the blur. And after a day of play, she literally woke up. Instinctively she disbanded the complex structures of large Orchestral works such as Beethoven’s “Missa Solemnis” (Gardiner/archive) and remained fine in the critical chorus locations, clean and clear.
While none of this “lightning-fast” transducer, which one model every detail right in front of your nose, but sound like somewhat anemic in the upper bass is the CM 9. The 9s played wonderfully full-bodied and could deny the CM affiliation despite their very open and bright tone mid-range. Means: sometimes it lacked on the dynamic kick. Not that it would have lacked her at the great orchestral tutti to maximum level. But seemed liberalize, seemingly “slower” than about a 703 (test 11/03) from the same home.
But also much more homogeneous. Just when voices like that of Lizz Wright (“speak your heart”/”stereoplay ultimate tunes”) managed a real electrifying performance of CM 9. There, single chassis were not (as so often in more way speakers) to hear. No, this only one sound source extremely believable three-dimensional brought the Mrs Wright in the listening room.
Credible because nothing, absolutely nothing of the Ruch, distinctive voice embezzled new CM and just right to hit the moving minor undertone. Or guitar music by Jack Johnson: here she showed every small overtone, each small finger noise and let the listener time to absorb the whole thing alone yet.
Some holistic has the CM 9. It offers neither the bass punch of a T + A TS 300 nor the agility of an audio physic Yara II superior. But compared to this class references the CM 9 draws their audience calm much more deeply in the music and in the recordings.
I like to confess that I longer have heard a lot with this speaker as actually planned. But it made it so much fun… And also the opportunity for some combination tests surrendered. Since 9 prefer to “fast”, thus rather bright sounding amplifiers with sufficient steam depends on the CM, I must strongly advise against combination with small tubes like the lyric TI 60. For she harmonized very well with two other amplifiers: the exposure XXXV and the Surrounder Yamaha Z 7.
Just the fine interplay with the Yamaha underlines how universal these CM 9 is actually. And with its homogeneity is quite far ahead even among homogeneous acclaimed B & W speakers…
