You knew that Pioneer is the world's top speaker manufacturer, right? All of that leading-edge experience went into these Oversized 6-1/2" 4-ways, and you'll instantly hear the results in your vehicle.
Composite IMPP Cone with Interlaced Dual aramid fiber
One of our major speaker breakthroughs was IMPP (Injection-Molded Polypropylene), which allowed cones to be lighter AND more rigid. Then we added long stands of Aramid fibers into the mix, for extra strength. Now, we’ve gone even further by adding a second type of Aramid fiber that makes the cone even stronger and tougher, without adding weight. So what does this mean to you? Tighter, more powerful bass. A rich, natural sound character with excellent midrange depth. And the durability to stand up to the high volume levels, humidity, and temperature extremes that thrash other speakers.
New Balanced-Dome Midrange with Laminated Polyester Fiber
Better technology, better performance: instead of conventional materials, we used a laminated polyester fiber in our new balanced-dome midrange, the same material used in the high-end REV-series speakers. The key to this material is that it is 30% lighter than conventional materials. That difference in weight means faster and more accurate response, for exceptionally clean, detailed music.
The TS-A1781R now handles a full 250 watts max. power (50 watts nominal). So, what did we have to give up? Not a thing. Along with bigger power handling, you still get the same high performance that all the TS-A’s deliver.
Designed for an Exceptional Fit
The Oversized 6-1/2" design is a perfect fit for many GM and Chrysler vehicles, and takes full advantage of the application with a larger cone for more powerful bass performance than a typical 6-1/2" speaker. For added install compatibility, a 3-hole adapter for use in many Chrysler vehicles is included.
