The speakers

         WL - 30 s is HuiLong invited HIFI professional team, after years of silence working on building a high quality shifi bookshelf speakers WL - 70 elder sister, is also used high-grade household style appearance, but WL - 30 s to use the light color wood grain of quietly elegant, refined, elegant refined gas, like the elegant style of ideal choice; 15 mm ultra thick density board for more stable solid body, reduce resonance box, keep the original sound source.

        HuiLong WL - 30 s is called the HIFI level high quality speaker, can say HuiLong superb speaker's work. WL - 30 s with 25 mm high ball silk membrane element + 6.5 inch bass unit combination of perfect speakers, sound sweet, rich details, distinct.
       WL - 30 s to use the most classic before and after the mature stage separation circuit board design, maintain the sound spectrum, mutual interference, level and bright.

          WL - 30 - s after level amplifier circuit is the ultimate source of system surging power, it is equipped with 160 w high power transformer, power reserve enough allowance. The power output is absolute advantage of WL - 30 - s, it has double track 120 w (RMS) of strong output capacity. Level after the whole circuit craft is excellent, the use of the technology of double deck glass fiber board and a large number of surface patches 

            WL - 30 - s, is a large quality is exquisite and dynamic product, in order to ensure the consistency of power amplifier chip timbre, WL - 30 - s is equipped with four stmicroelectronics launch of high-power TDA7294 DMOS amplifier chip, it than it used to be common power amplifier chip has greater dynamic range and strong power output. The power amplifier chip with large rated power 100 w mono, with high conversion rate and linear dc transmission characteristics, in the case of large load current and high voltage remains very low harmonic distortion. TDA7294 also integrates delay start-up circuit can effectively reduce the impact of the large current to the speaker when the phone is switched on, Internal short circuit protection and temperature protection circuit can control chip load in a timely manner. 

          WL - 30 - s on the wire HuiLong so much money at the cost of building the gold-plated integration sound box line 4 core. More use of wire line core coarse, impedance, and the joint part after dealing with the gilded dc consumption is lower and guarantee the purity of audio signal transmission. Exquisite gold-plated plug with black nylon shockproof mesh wire more high-grade, fever flavour is dye-in-the-wood.
