Acoustics ONKYO Monitor 2000

Acoustic system. Excellent acoustics with excellent presentation. Perfect condition. Bargaining is minimal. Link to my Instagram https://instagram.com/vintageakusticalmaty?igshid=OGQ5ZDc2ODk2ZA==See all my listings This monitor series speaker system is compatible with a variety of music sources thanks to the use of a pure cross-carbon and magnesium alloy diaphragm. Woofer A 34cm diameter woofer with a pure carbon fiber cone is installed in the low frequency range. Pure cross carbon diaphragm design; in which three layers of carbon fabric are laid with an angle offset of 30°; and the dust cap has a design; in which two layers of carbon are laid with an angle offset of 45°. This design exhibits rigidity unique to carbon in all directions and is a diaphragm; made from this material. Carbon fiber has a unique sound due to its low internal loss. However, we were able to increase internal losses without reducing stiffness; using newly developed epoxy resin as the bonding material; used in shaping cones. The Monitor2000 was the first time a cone was cast from pure cross carbon; and the rigidity (Young's modulus) is 12.7 times higher; than a paper diffuser. The magnetic circuit uses a large magnet measuring ? 200x? 95x25t and magnetic flux density 14,150 Gauss. This magnet is equivalent to a 38cm class block; and the weight of the block reaches 9 kg. Mid frequencies The mid zone is equipped with a composite cocker with a diameter of 10 cm; using a composite structure of a dome type with a diameter of 6.5 cm and a cone type with a diameter of 10 cm. A magnesium alloy is used as a diaphragm. Magnesium has large internal losses and the lowest density among practical metals (0.38 times more than titanium and 0 ;64 times more; than aluminum). This material is molded by Skoker to a thickness of 100 microns to ensure structural rigidity. Besides; The coating is obtained uniformly to a thickness of 6 microns using a newly developed vacuum resin deposition method; allowing the simple sound of magnesium to be realized. Skoker's superior internal loss suppresses unwanted resonance; therefore there is no need to attach damping material to the back of the dome and no excessive sound suppression occurs. A newly designed equalizer is installed on the front of the diaphragm to improve directivity. Is a magnet used as a magnetic circuit? 140x? 75x17t; magnetic flux density of 12,000 Gauss and a voice coil with a diameter of 65 mm. Tweeter In the upper range, a dome-shaped tweeter with a diameter of 2.5 cm is installed. This device uses a magnesium alloy diaphragm as a diaphragm; Also; as in SCOKER. The diaphragm thickness is 40 µm according to the device specifications; and a new design equalizer is installed in front to improve directivity. The magnetic circuit uses a magnet? 90x? 45x15t; magnetic flux density 18250 Gauss. NetworkThe network section uses a centralized single-point grounding system; which uses the know-how of amplifier technology. In this system, the grounding of each wire is concentrated at one point; which eliminates interference between units and networks and improves orientation. Besides; high quality materials with low resistance are used; low distortion level and high input impedance; and the sound quality is improved due to sufficient audibility. Case The Monitor2000's bass port is located on the rear panel of the system; to eliminate interference from the port. In the cabinet design, special attention is paid to the thickness and reinforcement of the plates: for partitions; top; 25 mm thick chipboard is used on the bottom and side plates; high rigidity 28 mm; high internal loss Apiton plywood for the rear panel and sufficient reinforcement for the overall weight of the system. 40 kg. The front baffle has a symmetrical arrangement of blocks to improve sound localization. In Monitor2000, smoothing attempts to eliminate the effect of reflection and diffraction of sound waves on the surface of the partition. The protrusion of the level control is also pressed inward; to make it flat; except for adjustments. Besides; there is no thick emblem on the surface of the partition; and careful measures have been taken; such as writing the model number by etching. In addition; by creating a gap between the surface of the partition and the secondary RUNET, the effect of reflection by the secondary RUNET frame is suppressed. Method
