2.0. 1(2.0.2) Product definition: it belongs to the definition of "X. 1", and the first two "2.0" in the name are X, which represents the current hifi2.0 matching box, followed by ".1" or ".2".
Product model: Suowei 2.0. 1 Low-frequency booster 2.0 There are three speaker families * * *, including: HD830T, HD840T and HD850T.
Among them: HD830T is a 3-4 inch 2.0 speaker +6.5 inch low-frequency booster-popular type;
HD 840T is a 4-inch 2.0 coaxial speaker+dual 8-inch low-frequency booster-standard;
HD 850T is a 5.25-inch 2.0 coaxial speaker+double 10-inch low-frequency booster;
Model meaning: This series of products is formed by adding low-frequency supercharging design on the basis of Suowei Shuangpao Wang 2.0 series products, so the first half of the model is the original model of Suowei Shuangpao Wang series, and the suffix T is the English prefix of Turbocharged turbo, which means the low-frequency supercharging system of 2.0 speakers.
2.0. 1 Audio performance and usage:
2.0. 1 speaker composition: The sound system composed of 2.0 speakers and a subwoofer with a certain transient response is 2.0. 1 speaker, which is an upgraded product of 2.0 speaker bass and also an upgraded product of 2. 1 satellite box and bass transient texture. That is, the 2.0. 1 speaker is the 2.0 speaker.
First, compared with 2.0 speakers:
① Structurally, 2.0. 1 is a split large-scale 2.0 system consisting of a set of standard 2.0 bookcases and an ultra-low frequency booster speaker (2.0. 1 frame) or a pair of ultra-low frequency booster speakers (2.0.2 frame). The framework of frequency divider is power divider+electronic frequency divider, in which the 2.0 bookcase uses power. The power amplifier adopts four-channel power amplifier, and the system is integrated in function control, which completely solves the fatal problem that the product 2.0 speaker cannot be connected to the active subwoofer on the port. In addition to the regular port, 2.0. 1 also has a dedicated input port for the subwoofer to adapt to the sound source equipment with the subwoofer sound source port.
② When using, the system works in 2.0 bookcase mode when the subwoofer volume is turned off, and 2.0. 1 (or 2.0.2) mode when the volume of the low-frequency booster speaker is moderately increased, which is equivalent to a standard electronic frequency division large HiFi 2.0 speaker system;
(3) In timbre, the frequency response of 2.0. 1 speaker belongs to ultra-wide band, and its frequency band should cover four frequency bands: treble, alto, bass and subwoofer. The low-frequency booster speaker effectively dives the bass of the 2.0 bookcase to the ultra-low frequency band, which comprehensively improves the fullness of music. By adjusting the low-frequency booster value of 2.0. 1 speaker, the low-frequency booster speaker and 2.0 speaker can be changed.
④ In terms of flexibility, 2.0. 1 speakers can be placed in many different ways, thus realizing different architecture modes (see the diagram).
(a) Users with small desktops can put the low-frequency booster speakers in any idle space, and only put a small bookcase of 2.0 on the desktop, but they can enjoy the playback effect of large floor-standing HiFi 2.0 speakers+active subwoofer (at this time, it is equivalent to super fever 2. 1 system);
(b) When the user has the conditions to install a tripod, the system can be used in the form of large-scale HiFi split electronic frequency division 2.0;
(c) When the user turns off the low-frequency booster speaker, the system can be placed in a 2.0 small bookcase;
(d) Users can choose a more suitable placement method according to their own use space and likes and dislikes;
B, compared with 2. 1 speaker:
(1)2.0. 1 The frequency response of the low-frequency booster speaker is a subwoofer, and the energy should be concentrated in the subwoofer.
(2) The satellite box with 2.0.1architecture is a standard 2.0 speaker, and its parameters are completely set according to the Hi-Fi standard, which can reach the level of listening to music independently, and the frequency range can naturally extend to the low frequency. There is no failure of 2. 1 between the middle and low frequencies, and there is no intermediate frequency collapse;
(3) The bass low-frequency booster channel of 2.0.1speaker has powerful low-frequency energy, as well as the low-frequency dive, low-frequency transient and low-frequency texture of the large HIFI2.0 speaker. Completely overcome the fatal defect of 2. 1 speaker subwoofer, which only growls and doesn't want texture;
(4) The left and right channels in 2. 0.1speaker can locate the bass with a sense of position in the stereo sound field, but the left and right channels in 2. 1 speaker can't represent the bass frequency band, and their bass positions depend on the position of the subwoofer, so they can't reproduce the stereo bass sound field positioning;
(5) The low-frequency booster speaker of 2. 0.1speaker adopts an external bass unit, which instantly reaches the level of a large HIFI2.0 speaker, overcoming many shortcomings caused by the built-in bass wind noise of 2. 1 speaker;
C, 2.0. 1 speaker selective control:
(1) Turn off the subwoofer volume of the 2.0. 1 speaker, and the system will work in the 2.0 state, which is suitable for listening to music at this time, and it is the favorite of middle and high-pitched enthusiasts with moderate bass;
(2) Turn up the subwoofer volume of 2.0. 1 speaker, and the system will work in the state of 2.0. 1, which is equivalent to the upgraded state of 2. 1 or large HIFI2.0 speaker. Suitable for movies, explosive music and heavy metals, and it is the first choice for music lovers who have high requirements on sound quality but love bass.
(3)2. 0. 1 Reasonable adjustment of the high-low balance and the sense of subwoofer in the sound box can become a playback system that adapts to various music styles and is the first choice of rational enthusiasts.
(4)2.0. 1 speaker is fully compatible with desktop 2.0 system, 2. 1 system and large HiFi2.0 system;
