Unsatisfied with your car's stock tweeters? Looking for one that delivers high frequencies at high volume levels with very low noise? Then you should go for a pair of Pioneer TS-B400PRO tweeters. Designed to produce impressive sound pressure levels and is inspired from Pioneer's history of making high-quality audio components, the TS-B400PRO is surely an upgrade to your old tweeters.
This 4-inch Pioneer TS-B400PRO tweeter has a titanium diaphragm and an impressive motor assembly, resulting in a loud and crisp high-frequency production. Its aluminum die-cast chassis gives the tweeter the durability to last for a long time after years of use.
The Pioneer TS-B400PRO’s voice coil can resist the effects of high temperature, so you do not have to worry even with extended periods of use while on the road, as it won't easily break because of temperature issues. It has an in-line crossover filter, so you can be sure that all the unwanted frequencies will be filtered out to protect your tweeter from blowing off.
The Pioneer TS-B400PRO can handle a nominal power output of 200 Watts per tweeter, and its peak power can reach up to 500 Watts at 4 ohms. Its sensitivity rate of 106 dB and frequency response of 3.5 kHz up to 27 kHz is impressive for its tiny size, allowing it to have a loud high-frequency performance with little distortion.
