Although Conch was patented for its proud cone design as early as 1935, it was not until 1998 when the company was founded that the technology was applied to car audio systems. The product classification of conch is 1 series, 3 series, 7 series, and Z series, of which 1 series is the most cost-effective, and Z series is the best. The signature silver foil cone that runs through the whole is eye-catching, but the most striking thing is its impressive timbre performance. The Z Series has always been known for its exceptionally accurate detail reproduction and strong dynamic response, with treble frequencies that surpass the limits of human ear recognition, with resonant frequencies as low as 818Hz. If the sound source and amplifier are properly matched, all kinds of music can be played with ease. However, to this day, resin foam aluminum foil is still only handmade, with a daily output of only single digits, and the price is naturally expensive, often selling at tens of thousands of yuan. Conch has an exclusive agent in China, and consumers can consult on their own. However, there are imitations on the market, and you need to carefully identify them when buying.
