Luccent Series Coaxial Speaker Kit Pair

Luccent sound quality is smooth and seductive with plenty of dynamic punch. Bass is fast， extended and energizing. The sound stage is huge and significant so that the listener feels as if they are hearing it live. Luccent Cone Material - The Luccent cone is comprised of critically damped black polypropylene with deep cone geometry for maximum stiffness. Its profile is curved shaped to offer a smooth high frequency response that will blend effotlessly with the response of the tweeter. Also features a long life rubber surround for smooth frequency response with long linear stroke for low distortion. Polymer Damped Aluminum Tweeter - A high end polymer damped aluminum dome tweeter that is truly the best of both worlds as it sounds smooth like the best silk dome while having the high detail and low distortion of the best metal dome. This tweeter is extremely musical and never fatiguing. A rear chamber heat sink gives high power handling capacity to allow a 2000 Hz Crossover Frequency. Coincident Tweeter Mounting - A coincident tweeter is mounted directly on the pole piece of the woofer. This allows it to be perfectly time aligned with the woofer and takes advantage of the woofer cone boundary as a natural wave guide.
