Treble: 60 x 32mm folding diaphragm tweeter unit
Bass: 6.5 inches (165mm) Curv &; RegPP braided antimagnetic bass unit
Weight (net weight):12.3kg/piece
Box size: height 346mm × width 220mm × length 286mm.
High notes:
Patented design, folding diaphragm, high efficiency magnetic circuit. Its diaphragm is folded into a diaphragm assembly with a length of 33mm x a width of 26mm by a very thin film with an etched aluminum voice coil. The expansion area of the diaphragm is 6- 10 times that of the commonly used 25mm dome tweeter diaphragm, so as to ensure accurate and clear music reproduction under large dynamic conditions and low distortion. Its squeezing sound mode can eliminate the inevitable vibration distortion of other modes, and the high frequency can reach 28kHz. At present, only a few high-end speakers on the market use this kind of treble.
Bass:
The woofer adopts Curv &；; RegPP (polypropylene) synthetic braided cone basin has the advantages of light weight, moderate internal damping and high rigidity. At the same time, the voice coil with high temperature resistance and long stroke design, aluminum alloy die-casting basin frame, high-efficiency magnetic circuit and antimagnetic design, and short-circuit ring are added in the magnetic circuit to further reduce distortion, improve impedance characteristics and improve the power carrying capacity of the unit.
Power amplifier:
After electronic frequency division, two independent power amplifiers drive treble and bass respectively. It has good linear phase characteristics and sufficient dynamic response. In order to replay the high-pitched short pulse signal without compression and protect the high-pitched unit from damage, a high-performance flexible compression circuit composed of precision optocoupler and special integrating circuit is specially set in the channel of the high-pitched unit. The bass channel is specially equipped with fast circuit breaker protection and lower cut-off frequency circuit, which makes the speaker work more stably and reliably. In order to adapt to the acoustic characteristics of different use environments, three groups of accurate frequency equalization adjustment switches are specially set for users to adjust flexibly.
