- Speaker Type: Component System — separate woofer and tweeter with an in-line crossover for cleaner separation of bass/mids and highs, improving overall clarity in a car environment.
- Midrange Size: 6.5" nominal — standard diameter for many door panels, offering substantial midbass presence when paired with appropriate enclosure and mounting.
- Tweeter Size: 1.0" (25.4 mm) nominal — small, crisp highs with reduced crossover interaction when mounted in allowed locations.
- Impedance: 4-Ohm — common automotive load that works well with single- or multi-amp systems and typical head units.
- Frequency Response: 60 Hz – 20 kHz — covers bass to treble ranges to reproduce most music with full-range detail.
- Sensitivity: 89 dB @ 1W/1M — relatively efficient, translating to practical volume from available head-unit or amplifier power.
- Power Handling: 40 Watts RMS / 80 Watts Max — defines continuous and peak power capabilities; helps prevent under- or over-driving in typical audio setups.
- Crossover: Tweeter High-Pass (HP) at 12 kHz @ 6 dB/octave — filters low frequencies from the tweeter to reduce distortion and ensure smooth highs.
- Tweeter Mounting Depth: 1.06" (26.88 mm) — installation depth requirement to ensure fit behind doors or panels without interference.
- Midrange Mounting Depth: 1.97" (50.1 mm) — indicates space needed in mounting location for proper diaphragm movement.
- Cones/Domes: Mica-injected polypropylene cone (midrange) and Mylar balanced dome (tweeter) — selected materials contribute to rigidity, damping, and high-frequency response.
- Grille/Trim Ring Included: Yes — provides a finished appearance when installed and helps protect components.
- Mounting Hardware: Yes — simplifies installation alongside the factory mounting points.
- Warranty: 1 Year — standard coverage for this Prime component system.
- Compliance: CEA-2031 Compliant — meets industry guidelines for car audio measurement and specification documentation.
- Packaging: Sold in pairs (two speakers per package) — ready for a complete front or rear channel upgrade in many vehicles.
The R165-S is suited to a car audio build aiming for clearer high-frequency detail and more controlled, accurate midbass from a factory-like replacement fit. The two-way design with a dedicated tweeter and in-line crossover reduces frequency overlap, while the included grille and mounting hardware streamline installation in OEM spaces.
