The Pioneer TS-T15 is a 0.75-inch tweeter designed for use in any vehicle. The compact size of these 1-way car speakers sacrifices no sound quality yet allows users to mount the speakers virtually anywhere within the vehicle, including on the pillars. With 120-watts of peak power and a nominal power handling of 40-watts RMS, these Pioneer car speakers can handle some of the more powerful stereo systems available. The enclosed design of the Pioneer TS-T15 makes it possible to surface mount or flush mount in the vehicle. The soft dome of the tweeter is made of styrene rubber-coated polyester for durability. The polyimide voice coil of these 1-way car speakers is in Neodymium magnetic fluid for optimal quality. The round mesh grill of these Pioneer car speakers is heat-resistant, so they can withstand the summer sun in uncovered parking areas. The Pioneer TS-T15 offers two-way surface mounting with a twisting mounting plate and a double-faced adhesive tape for simple, quick, effective mounting anywhere in the vehicle.
