Pioneer’s next generation of TS-A series speakers offer improved bass and dynamic range, higher power handling and a new cosmetic design. The TS-A speakers are designed to replace the vehicle’s factory installed speakers and produce improved sound quality at exceptional value.

The TS-A line includes a new highly rigid Multilayer Mica Matrix Cone structure for a wider dispersion of sound with deeper bass, and a new tweeter designed to deliver an improved range of mid to high frequencies and produce optimized sound at higher volumes. The technology improvements offer better performance, enhanced sound quality and the ability to play a larger variety of popular music with heavy bass including hip hop, dubstep, and alternative rock.
Woofers: The multi-layer mica matrix cone was developed to provide an extra light, yet rigid diaphragm to reproduce full, rich sound.

Surrounds: For durability and a smooth response, each woofer uses an elastic polymer (synthetic rubber) surround.

Midrange: Each speaker has a 1-1/8" balanced dome midrange with a neodymium magnet.

Tweeters: Each speaker uses a 3/8" dome tweeter and 3/8" dome super tweeter made from PET (Polyethylene Terephthalate) film for crisp, clear highs.
