Powerbass S-6903 6"x9" Coaxial Speakers

Powerbass S-6903 6x9 Tri-Axial Coaxial Speakers are an OEM drop-in replacement engineered to upgrade 6x9 openings with a built-in midrange and tweeter for expanded, coherent sound in a single install.

• 6x9" Tri-Axial Speaker System: integrates midrange and high-frequency drivers in the 6x9 frame for a three-way sound.
• OEM Drop-in Replacement Design: fits standard 6x9 openings with no modification.
• 2-layer Paper DDC Cone / Silk Dome Tweeter: DDC-coated cone with a silk dome tweeter for controlled bass and smooth highs.
• Double Pressed Treated Foam Surround: durable surround preserves cone alignment and dynamic excursion.
• 10 oz Motor Structure: compact motor supports fast transient motion across passages.
• 20 oz Magnet Size: larger magnet improves flux control and overall handling.
• Shallow Mounting Depth: 3.3 in mounting depth enables installation in tighter spaces.
• EFF Motor Structures (Efficient Flux Field): designed for efficient flux field within the 6x9 form factor.
• Rigid Tooled Basket With Flat Black Finish: sturdy frame minimizes vibration and maintains alignment.
• 2" PEI Dome Mid-range and 0.75” Tweeter Ring (Sound Expander Lens): dual-dome setup with dispersion lens enhances coverage.
• Nominal Impedance: 4 ohms: standard car-audio impedance that pairs with common amplifiers/head units.
• Sensitivity (1W/1M): 90 dB: indicates on-axis efficiency at a fixed distance.
• Frequency Response: 45 Hz - 20 kHz: broad bandwidth from deep bass to clear highs.
• Power Handling (RMS/Peak): 70 / 210 watts: continuous and peak power ratings for dynamic music passages.
• Magnet Size: 20 oz: magnet scale contributes to control and linearity across excursion.

In a car audio build, the S-6903 is ideal for upgrading factory 6x9 setups where space is limited but you want a coherent, full-range sound from a single component. The OEM drop-in design simplifies installation, while the tri-axial arrangement provides integrated midrange and high-frequency reproduction for more complete listening from 45 Hz to 20 kHz. With 4-ohm impedance and 90 dB sensitivity, it pairs well with typical head units, and its 70 W RMS / 210 W peak handling offers headroom without external components.
