It seems that creating new flagship CMS developers Bowers & Wilkins decided to bring together a series of SM and 800, otherwise how to explain the appearance of the new model of the external, top mounted tweeter? If you put a number CM10 and former senior CM9, then, in addition to the tweeter, you can also see the difference in the number of emitters. Due to the transfer of the tweeter at the top SM10 free up space on the front panel, allowing to install additional third woofers. The proportions of the body and the size of menilis slightly increased mainly depth. Such a maneuver with the bass-section in the SOM to extend the frequency range on how many non-Hz down, and most importantly — increased sound pressure acoustics, so it can be installed in a room larger.
Finishing options, the model SM10 four. Veneer walnut or wenge pink supplemented timeless black and white piano lacquer. With the integration of the interior of the problems should arise. If someone (like me), received fundamentally do not like much at the lower-rate, you can try to do without it. It serves mainly to enhance the abutment-ity (according to the strict safety requirements of the EU-) more vibrorazvyazki and Uwe-crease body weight without participating By direct-tively in the creation of acoustic design. Technically it can not be installed. But do not forget that any change in the con-struction of a user makes at your own risk with all possible consequences.
Acoustic design of enclosures — F zoinvertor, of course, corporate Flowport. Woofers operate in a single acoustic-sky volume and reproducing frequency band from 28 to 350 Hz at -6 dB (according to the manufacturer). Woofer cones are not as simple as it may seem initially. They are two-layer, which allows the combination of stiffness and lightness Kevlar base with acoustic properties of the paper coating, which imparts sound of any acoustic liveliness, expressiveness and naturalness.
Material cone midrange radiators — Kev-lar in its pure form, which is easily recognizable by ha teristic yellow. Large 150-mm differential-fuzor installed on the company’s suspension FST, which is a foamed polymer. As with conventional suspension, it provides non-necessity free running of the diffuser, but it forms a better seal around the perimeter of the diffuser and suppresses parasitic oscillations. MF emitter is assembled in cast aluminum cor-zine with a maximum open design, without causing compression and reflections behind the diffuser. Speaker vibrorazvyazan fully with the housing thanks to a rather tricky fastening technology borrowed from the older 800 Series Diamond. It is installed in a milled mounting hole on the front panel is drawn from the outside and a long pin that passes through to the back wall. Place mounting studs and seat dynamics have special anti-vibration pads, so rigid mechanical design «Speaker + hairpin» is not in contact with the body itself. During transport, the acoustics are special transport screws allow to fix the radiator tightly, so that there is a potential opportunity to assess the sound acoustics vibrorazvyazkoy midrange transducer and without it. It should be noted, the difference is quite noticeable.
It is also almost completely vibrorazvyazan with the body and the new tweeter. After removing the transport safety catch he receives a considerable degree of freedom, relying only on the soft vibration damping material. Separate tweeter streamlined body gives him another significant advantage in terms of diffraction. Sound waves practically pereotrazhayutsya how it is when you install the RF transmitter on a flat front panel. This means that we hear only the sound waves that Vor miruet speaker cone, without mixing the secondary reflections from the surface of the body acoustics. Himself tweeter mounted in the model SM10 has double reinforced aluminum dome, the back side is working with the tapered tube-loaded Nautilus. Rose-weighted stiffness and damping of the dome of the radiation produced during the back, minimizes distortion and allows you to extend its frequency range to 50 kHz -6 dB.
All radiators are initially designed in such a way that their response did not require a significant correction via crossover. As a result, do crossovers obtained extremely simple, as transparent as possible for the alarm. So, for example, Mr. tweet using a single capacitor whose value is chosen by ear.
All technological solutions, starting with the material ma-diffusers and ending with large body mass loudspeakers, directed p. primarily at minimizing distortion and providing the most pure, clear sound. And when listening to really create a feeling of absolute transparency, purity, and some natural ease in giving any musical material. This is especially felt in the upper middle and high frequencies — the area of responsibility of the tweeter. With proper selection of the listening position when the listener’s ears are on-axis tweeter, the scene is-built exclusively for sure, and the transfer of the atmosphere, the WHO-spirit is excellent. Mid-Play, an exact, relief, timbres and shades ulcer-ing clearly defined. Lower middle dense and richer than the top, resulting in a range of voice and tone most basic tools most expressive and voluminous. Bass plays surprisingly smoothly and clearly. With solid power and tangible depth he does not dominate and free from any specific overtones.
High resolution and Solid-nye dynamic characteristics acoustics SM 10 others require high quality audio components com. In this case, in obtain great pleasure from proslushi-tion the most expressive recordings of classics with dramatic pauses, hang in abso-lute silence and sharp transitions in the fort-fortissimo, in general, the speaker is versatile enough by genre and copes well with any music . The main criterion for the choice of music could be perhaps that the recording quality as the ability to detect faults in the SM 10 is as high as the ability to reveal the advantages of material being played. Lovers of pure collected and clear sound speakers is required to audition.
The middle line response rather smooth on the line, but in the zone of the tweeter face all the signs of a narrow focus. The level of distortion has turned out not the lowest. The acoustics were new and possibly additional 100-200 hours warming would improve results. Graph impedance has significant spikes, including in the region of low frequencies. Even with high-sitivity Chuv measured without a powerful amplification do not succeed.
