DS18 G4XI GEN-X 4" 2-Way Coaxial Speakers 40 Watts Rms 4-Ohm

The DS18 G4XI GEN-X 4" 2-Way Coaxial Speakers deliver 40W RMS (120W max) from a compact 4-inch frame, built with a steel basket for vehicle-grade durability and long-term reliability. While designed for amplifiers, they can be used with many 4-ohm factory amplifiers and offer clearer sound and greater range than OEM speakers.

• Nominal Diameter: 4" (101 mm) – compact size fits in typical door or dash openings.
• Nominal Impedance: 4 Ohms – standard load for many in-vehicle amplifiers, balancing power delivery and damping.
• RMS Power Handling: 40W – continuous power rating; use an amp that can deliver clean power without clipping.
• Maximum Power Handling: 120W – peak capability for short musical transients.
• Sensitivity: 84 dB (1W/1m) – efficiency; higher values mean louder output from the same power.
• Frequency Response: 80 Hz – 20 kHz – covers bass to treble; deep bass relies on the overall system, not just the speaker alone.
• Recommended High-Pass Crossover: 90 Hz – protect the woofer and optimize integration with other speakers in a system.
• Design: 2-Way coaxial with woofer and tweeter – simple installation with full-range performance.
• Tweeter: Mylar Balanced Dome – adds extended high-frequency detail with smooth response.
• Woofer Materials: Paper cone, rubber surround, steel basket, Ba ferrite magnet – durable construction for daily driving conditions.
• Voice Coil: 1" (25.5 mm) ASV coil – robust for heat and excursion in a compact package.
• Overall Dimensions: 4" diameter, 2.4" depth; with grill: 5.28" diameter, 2.46" depth – installation footprint and grill compatibility.
• Weight: 0.45 kg per speaker – lightweight for easy mounting in tight spaces.
• Grill Included: Yes – protects drivers in aftermarket installations.
• Pair: Pair – ships as a matched pair for common door/dash installs.

In a car audio build, the G4XI pairs a compact 4" woofer with a 1" Mylar tweeter to deliver cohesive, wide-range sound from a small footprint. The 4-ohm impedance and 40W RMS rating align with mid-power amplifiers, while the 80 Hz–20 kHz range provides clear vocals, detailed highs, and confident midbass. The steel basket and durable cone resist road-induced flex, making it suitable for mounting in doors or dashboards. A 90 Hz high-pass crossover recommendation helps tailor the system and protect the woofer from over-excursion. The included grill protects the drivers and preserves a clean aftermarket installation.
