Seas TPCD C16NX001-X-TPCD (E0121-04/06) Coaxial -146mm- 4 ohm
Metamodal™ TPCD technology
We are happy to introduce yet another addition to our coaxial driver line up. Featuring Metamodal TPCD diaphragms from Composite Sound, the C16NX001/X, E0121-04/06 is truly top of the line, meticulously engineered for ultra-high performance and exceptional sound quality.
Ultra-high performance coaxial driver, featuring a customised Composite Sound Metamodal™ diaphragm for both the woofer and tweeter. This advanced material, now in its second generation, is engineered to a perfect balance of low weight, high stiffness, and controlled damping, ensuring unparalleled sound quality. The magnet systems are FEA optimised with precisely fitted copper parts for outstanding linearity, high power handling and minimal distortion. The use of titanium voice coil formers enhances force transfer and enables low mechanical damping, resulting in remarkably clean, transient sound reproduction that reveals the intricate micro-details the music.
The innovative crown-shaped copper tweeter support allows for the addition of damping material, effectively eliminating any resonance from the cavity between the tweeter housing and woofer voice coil former. The coaxial arrangement of the tweeter and woofer makes the driver an exceptional point source, providing a large and precise sound imaging that elevate the listening experience. Its compact design makes it perfect for bookshelf speakers, or as the top-end driver in a 3-way system. It’s also exceptional for surround setups, where the even dispersion from the coaxial point source ensures a seamless and immersive audio experience. Pair it with a subwoofer to elevate your sound to a whole new level. You will find an impressive sound clarity, with the uniform dispersion only a premium coaxial driver like this can deliver.
