Alpine 6.5" 2-Way Coaxial Car Speakers SXE-1726S

The Alpine SXE-1726S are 6.5-inch 2-way coaxial car speakers engineered to deliver clear midrange and detailed highs with a 40W RMS (220W peak) handling and a wide 60Hz–20kHz frequency span.

These compact coaxial speakers combine a Kapton-voiced woofer and a neodymium-tweeter assembly built on a ferrite magnet structure to balance durability with performance. Designed for direct-fit installations and aftermarket upgrades, the SXE-1726S emphasizes natural vocal reproduction and crisp treble while keeping power requirements modest thanks to a 4-ohm nominal impedance.

How will these speakers affect my car audio clarity?

The SXE-1726S focuses on midrange definition and treble detail, improving vocal and instrument presence compared with many factory speakers. Their two-way coaxial design places the tweeter close to the woofer axis, creating a coherent on-axis soundstage for listeners seated near the driver.

• Frequency response 60Hz–20kHz for broad coverage of vocals and highs
• Kapton voice coil for controlled midrange performance
• Tweeter magnet made of neodymium for sharper treble articulation

How much amplifier power do these speakers need?

Each speaker is rated 40W RMS with a 220W peak capability, so they pair well with factory head units or modest aftermarket amps. The 4-ohm impedance is standard for car audio, letting common car stereos drive them efficiently without demanding high-wattage amplification.

• 40W continuous (RMS) per speaker for reliable everyday listening
• 220W peak for short, dynamic passages without clipping
• 4-ohm nominal impedance for compatibility with most car stereos

What materials and design details improve longevity and sound?

The SXE-1726S uses a Kapton voice coil and a ferrite woofer magnet for thermal stability and consistent response over time. A neodymium tweeter magnet gives a compact, efficient high-frequency driver that improves treble clarity while minimizing added weight and depth behind the mounting plane.

• Kapton voice coil resists heat and maintains coil geometry under load
• Ferrite woofer magnet for sturdy low-frequency control
• Neodymium tweeter magnet for efficient, detailed high frequencies

How easy is installation and where do these speakers fit?

The SXE-1726S speakers are designed to fit common 6.5-inch mounting locations in doors and rear decks with compact depth for many vehicles. Their coaxial format reduces wiring complexity because the tweeter is integrated, making them a straightforward upgrade for DIY installers and professional shops alike.

• Standard 6.5-inch size for broad vehicle compatibility
• Coaxial design simplifies wiring and reduces install time
• Slim profile fits many shallow-mount applications

Who is this for? The Alpine SXE-1726S is aimed at drivers seeking a reliable, affordable step-up from factory speakers—people who want clearer vocals and more detailed highs without installing a separate component system or a high-power amplifier. They suit commuters, weekend drivers, and anyone replacing worn stock speakers with a compact, well-balanced coaxial option.
