1. The bass inductor adopts pure copper inductor with a diameter of 57mm, and the treble inductor adopts a skeleton inductor with a diameter of 41mm. At any cost, it uses for M&L- silver foil audio capacitors from Italy. Performance2. Bass inductance + polymer magnet to enhance the sinking of the bass, reasonable circuit + high-quality components + high cost performance = correct sound3. The role of ingenuity is full of materials. Every component has been carefully . From material selection to finished products, every procedure is strictly controlled. Every component is after repeated tests, just to achieve better sound quality.4. If you want your audio details to be outstanding, the sense of hierarchy will be more distinct and prominent; choosing it is equivalent to choosing a surprise.5. Silver foil capacitors from Italy are very high-priced products. Silver foil capacitors made is specially for audiophile. mg is used in -connection circuits, and the width of the sound range is immediately extended by 50%.Product Model: JBL612 (high and low two-way)Power: 350WImpedance: 4-8 ohmsCrossover point: about 2450HzFeatures: A capacitor is added to the bass output position to make the bass frequency smoother. This crossover is installed on the bookshelf box, which reflects the low frequency better. It is suitable for the performance of human voice and string music. You will find that the middle and high frequencies are particularly clean and pleasant, suitable for small rooms such as bedrooms, offices, tea rooms, etc.size: 148 x 95mmMaterial: plasticcolour: As shownPackage Contents: 1 x Treble and bass 2-way frequency dividerOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
