* Titanium Dome Tweeter with Aluminum Voice Coil: 1 inch (29mm) Titanium dome delivers a superior sound quality over aluminum with a very smooth high frequency with the added benefit of additional output
* Nylon Surround on tweeter: Nylon reduces harsh distortions which can develop on the surround in the transition point from the titanium tweeter dome to frame where the surround mounts
* PA66 composite Baskets with Glass Fiber reinforcement: PA66 is a composite cast material designed to be used in future orbital spacecraft. Its purpose is incredible strength but lightweight. PA66 is what NASA uses to eliminate metal parts with composites
PA66 is far more temperature and chemical resistant than standard plastics or ABS. This is important when developing low midrange and bass frequencies in a small diameter driver. Reduce the flex in the frame and you tighten the sound by eliminating weak points in the mounting system
* Mica Filled Poly Cone: Deep bass tones with musical midrange frequencies
