MarkAudio NC7_MAOP 1 book shelf speaker

The development of the NC7v2 is a sister machine NC11 the Fragship model. The MAOP7_v2 is an excellent model that plays flat up to 34000Hz (± 6dB), and the lightness of the drive weight is 3.3 g (MMS3.8g) is very attractive. The resonant frequency (Fb) can also be expected to be 50Hz, and the balance of the basic elements of music is good and very attractive. We offer two kinds of model NC7v2_WNT (Walnut Solid Wood) and NC7v2 _ MW (Hard Maple/Walnut Solid Wood Combination) made by craftsmen who manufacture musical instruments using high-quality solid wood to match this dynamic and delicate driver.

For hard maple/walnut, maple is hard and has good transmission characteristics, so it is fast to rise and good localization is attractive.

Walnut has high dumping factor (suction force of sound) to the weight of specific gravity, so indirect sound such as hall tone of the concert hall is richly reproduced.

MAOP(Micro-Arc Oxidation Process)

MAOP treatment is the process of creating crystals while oxidizing the surface of the aluminum magnesium cone over a long period of time in a solution of an alkali electrolyte with a very strong voltage (700V). The effect is to dump a resonant wave of sound that is said to pass through the surface of a cone using metal by this crystal. In conventional metal cones, the micro-resonance pattern passing through this surface was transmitted to the frame as it is, but this MAOP treatment has realized the dumping effect close to the pulp cone with the metal cone itself, which was impossible until now. This is because it realizes very flat frequency characteristics and is said to be "a silky and silky smooth audio driver."

The MAOP_7v2 uses rectangle (flat angle) copper wire for the voice coil Because the conversion efficiency in the magnetic field is about 30% more efficient than the round wire, the driving weight (MMD) can be reduced, and the eddy current of the middle range can be reduced, and the surface area of the coil can be designed large enough It contributes to the sound quality of P _ 7v2 throughout the whole area.The MAOP_7v2 plays flat up to 34 kHz. Xmax (amplitude) 4.5mm long stroke and drive unit total weight (MMS) 3.9g with a combination of 100μmm ultra-thin alloy cones, this best-selling model combines delicate medium-high and low-distortion purity bass.

Balance between the delicacy of hard maple and the beauty of walnut sound quality.

Hard maple wood is very hard and has high specific gravity, so it is wood with good sound transmission characteristics. This is why it is often used for guitar necks. Therefore, the contours of the cymbals and the details of the reverberation sound are reproduced. We used hard maple on the baffle surface and added walnut to the side panel to create a system with a balanced contour and three-dimensional feel. Enjoy the MAOP7 sound of real, delicate musical expression and density that you have never experienced before. This model is modern is a matte urethane finish which is often used in Nordic furniture.

Features of hall tone and music space.

The nature of walnut material is characterized by heavy hardness and less crazy, especially reflection and indirect sound are reproduced beautifully. It is used for various instruments. Since it has a moderate dumping ability, it has a warm expansion throughout the music and is ideal for enjoying the sound of the concert hall space and the overtones of the instrument. Traditional urethane gloss finish.

The rigid maple material does not attenuate high range, so the rise is very good and the reverberation is good. It is recommended for genres that have melody and contrast.
Walnut is ideal for classical performances in halls that take advantage of reverberation.

Oval Bus Refport

The sound of the bus reflex is bright, energetic, and the design method of the finished speaker system, but some people prefer the smooth, ultra-low characteristics of the acoustic suspension type. Therefore, in order to reduce the sudden attenuation of the bath reflex, a solid material is superimposed and the oval structure is adopted, and the design aims at "good tokotori" which is sealed with the bus leaf.

Craftsmanship

I was struck by the beauty of the finish by unpacking the NC7v2_MW sent from the Matsumoto factory. The finish of this beautiful top plate is impressive. It is made of 5 solid wood, but it is like a single board even if touched by hand.

The beauty of the Nature Collection series is more beautiful than the luxury furniture of the living room by selected materials and careful processing by experienced craftsmen.

Difference between and

The difference between NC11 and NC7 sound quality makes NC7 more delicate than NC11, making it ideal for listening to string chamber music. In contrast, the NC11 demonstrates its true value in grand spatial expressions such as classical concerts in large halls and organ performances in churches.
The maximum input is for NC7 units, but the tolerance increases by fitting into the enclosure and . Since the unit is 35W for NC11, the actual maximum input is about 45W.
Since mark audio speakers provide data that is designed and adjusted not only for viewing the front of the audio set but also for viewing the wonderful sound even in the offset state, it may seem inferior when comparing only the specs with other products.
