Show original supplier description
The SoundXtreme ST-460 coaxial car audio speakers are designed to replace low-quality factory speakers, offering an immediate improvement over OEM audio systems. This 3-way speaker system boasts a 440-watt peak power handling and a frequency response ranging from 60 Hz to 20,000 Hz, with a sensitivity of 88dB. The construction includes a 1/2" Polyether imide (PEI) balanced dome tweeter and a polypropylene mid-woofer cone, supported by a neodymium magnet motor structure and a stamped steel frame basket. Key technical details include EVC (Extended Voice Coil) technology for enhanced performance, a 4-ohm impedance, and a shallow 1/4" top-mount depth, with a cutout dimension of 3-3/4". This package contains four ST-460 speakers, making it suitable for upgrading the audio in multiple locations within a vehicle. These speakers are intended for in-car music listening and are compatible with car mounting types. The product description also notes that products used commercially are excluded from certain protection plans.
