  • Composite IMPP Cone Woofer Using Interlaced Dual aramid fiber
  • 1-5/8" Balanced Soft Dome Midrange

The TS-A531P is a high-octane example of what world-class speaker technology can do for music.

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.

Power Handling
The TS-A531P now handles a full 180 watts max. power (30 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.
