Monitor speakers are the first choice for audiophiles, but for the salaried first-timers, the high price of the speakers makes them prohibitive. Make your own speakers, the price is only 1/3 of the similar finished speakers, and you can get the happiness of successful production. The author used T & T's excellent No. 1 monitoring system kit to make a bookshelf speaker, and received unexpected results. The overall effect reached the Hi-End level, but the price was only 1/3 of the Dushi Swan M1 monitoring box Interested parties may wish to try.
T & T all uses the British special loose-pressure wool basin, no matter the low frequency limit or the transient response, it is better than the ordinary wool basin on the market (most of the domestic market is the compact wool wool basin). The No. 1 monitor speaker belongs to the Hi-End system. It has a luxurious and beautiful appearance and pure and sweet sound. The structure of this speaker is shown in Figure 1. The external dimensions are 450 × 240 × 300mm, and the left and right corners are cut above the box. In addition to its decorative effect, it can also improve the mid-to-high frequency characteristics.
Excellence 1 adopts the typical two-way frequency-inverting structure, the mid-bass is W-180D bullet wool basin, the magnet is enlarged, has a 20mm long stroke, the super large magnetic circuit structure, integrated low-carbon T-iron, upper splint The thickness is up to 6mm, which fully guarantees high power and dynamic, and overcomes the shortcomings of the relatively low efficiency of the wool basin. The aluminum bullet head dust cap can effectively suppress the distortion caused by the resonant cavity, reduce the third harmonic distortion, and improve the intermediate frequency characteristics. Compared with the plastic phase plug, the aluminum has better heat dissipation performance. Because the bullet is located in the center of the basin, it is completely separated from the sound basin and the voice coil, which ensures the sound image localization ability and sense of space behind the speaker, and improves the clarity of the sound. W-180D cone basin uses ceramic powder spray basin, which has good rigidity and moderate internal resistance, so that the unit has flat frequency response and low distortion, and has a good impulse response. The Tweeter No. 1 is H-600Q. It is a 28-core treble, transparent silk film, magnetic fluid cooling, sensitivity up to 90dB, fine sound quality and excellent layering.
The No. 1 frequency divider is shown in Figure 2. The two-wire crossover input is adopted, and the inductances are all hollow coils made of high purity oxygen-free copper enameled wire. The key capacitors are MKP high-quality polypropylene capacitors. The tweeter path has a "noise suppressor" connected in parallel at both ends of the main capacitor. Because of its positive temperature characteristics, it has an absorption effect when the high-frequency odd-order harmonic amplitude is large. At the input end of the speaker, an LC circuit connected in series by a small inductance and a small capacitance is connected in parallel to suppress the interference motion. The main parameters of the speaker are as follows: sensitivity ≥89dB, carrying power ≥250W, total harmonic distortion <2%, frequency response about 40Hz ~ 20kHz. The excellent performance of No. 1 speaker is not bad. Although it is a bookshelf speaker, the bass is quite full and the explosion is good. It is suitable for playing classical music and symphony.
