TS-A1683R Features Carbon Graphite IMPP Interlaced Aramid/Basalt Fiber Cone
One of Pioneer's major speaker breakthroughs was IMPP (Injection-Molded Polypropylene), which allowed cones to be lighter and more rigid. Pioneer then added long stands of Aramid fibers into the mix, for extra strength. Now, they've gone even further with the TS-A1683Rs, adding basalt and carbon graphite interlaced with long aramid fibers to provide strength and rigidity that powerful bass sound requires. High-density compressed internal architecture is resilient, stacks up against high power well and transfers sound quickly. The result is full-bodied, rich sound with midrange depth that conventional IMPP cones cannot match, and the durability to stand up to the high volume levels, humidity, and temperature extremes that thrash other speakers. Large Diaphragm Tweeter
The newly developed tweeter disperses sound more widely with superior control, providing listeners with the best sound under all conditions, regardless of listening position or car. And the 1" mounting depth achieves more flexible installation. Heat Resistant Polyester-Imide Resin Voice Coil Wire
Creating mechanical energy is hot work, especially at high volume levels. And as we all know, heat can cause distortion. That's why the TS-A1683R uses a heat-resistant polyester-imide resin voice coil wire. It allows the voice coil to handle more heat, improving input power handling as well as reliability. So go ahead. Turn it up. Power Handling
The TS-A1683R now handles a full 280 watts max. power (40 watts nominal). Along with enhanced power handling, you still get the same high performance that all the TS-A's deliver. |
