American audio,It can be regarded as a straight man in the audio industry,The sound is straight,There is tension in the big dynamics,The listening feeling is very cool。 Especially if the outfield display car is changed in the United States, it will have a very explosive effect. But this Rockford rifle T4 is a rare SQ sound quality speaker in the American audio, just like Qin Hao, although every sentence is a proper straight man quote, but Yi Nengjing's every sentence he responds, every action can see his careful care, this happiness, who can stand it? There is a tiger in the heart, sniffing the rose, and it is precisely because of this that Germany's "CarHiFi" is recommended by six stars.
The sound quality of the American SQ was produced in Europe
Rockford Rifle T4, the American SQ three-way speaker, includes two 6.5-inch mid-woofers, two 3-inch midrange speakers, and two 1-inch tweeters. It is said that in order to retain the coolness of the T4 in the United States and have more SQ sound quality details, Rockford United States Rifle sent the T4 to the HiFi speaker factory in Europe for production.
The 6.5-inch mid-woofer uses a carbon fiber oiled cone, which is similar to the material of Moray's flagship speaker, and is more mellow and warm in the performance of the human voice. However, the 38-core large voice coil and neodymium magnetic strong drive retain the great dynamics and tension of the American speaker, and the design of the magnetic circuit is also very distinctive, which is composed of six cylindrical neodymium magnets, which can withstand a maximum power of 300W; The convection design of the middle heat dissipation tooth allows the speaker to cool down quickly and has high stability. It is worth noting that in the 6.5-inch similar woofer, it can achieve 40Hz low-frequency diving, which is really rare, and T4 can be said to be a three-way speaker that can really fill the low frequency.
3-inch midrange speaker, using the same material and product design as the mid-bass, to maintain the consistency of timbre, 20.4-core voice coil and neodymium magnetic drive, 200Hz to 10kHz ultra-wide frequency, not only can excellent connection between high frequency and low frequency, but also has more thickness in the performance of the mid-frequency vocal segment, making T4 in the interpretation of audiophile vocals, not inferior to European audiophile brands. In addition, the mid-woofer and mid-range speaker are equipped with a metal horn grille and a concave design, which makes it more unique and aesthetic if it is installed after the mold is inverted.
The 1-inch tweeter adopts silkworm dome diaphragm and neodymium magnetic drive, and the broadband design makes the high frequency extend from 3kHz to 30kHz, which can fully reach the ultra-high frequency band, excellent resolution, and rich details. It is also very simple to install, can be replaced in situ without damage, and is equipped with different mounting brackets to facilitate the installation of tweeters.
High-power drive, active design
It can be seen,Rockford rifle T4There is no matching crossover,This three-way frequency needs to be set with DSP to do active crossover,The crossover point recommended by the official rifle is the treble 5kHz@24dB,The midrange is400-4kHz@24dB,The bass is 350Hz@24dB,And the American crossover modulation method mostly uses 24dB slope,So that the crossover design can get the effect of zero phase difference。 From the point of view of the selection of frequency crossover points and the parameters of power,T4It is a three-way product that needs to drive fever with high power,The sound is also dynamic and tense,But it is not straightforward and flat,But there are rich details,Xiaobian thinks"There is a tiger in the heart,Sniff the rose"Describe it as RifleT4。
