Description
The DC Audio NEO Elite 3.5 18" Subwoofer is a built-to-order high-motor-force driver designed for SPL and ground-pounding performance, with an open motor design to help keep the 3.5" voice coil cooler during extended, high-power play.
- Extremely rigid paper cone assembly: Keeps the cone stable at high excursion for tighter, more controlled bass.
- Large Roll “LR” Multilayered polymer foam surround: Durable suspension that maintains alignment and linear cone movement under heavy loads.
- Polypropylene dust cover with DC logo: Lightweight protection with minimal resonance to preserve signal integrity.
- (5) 3.5x10” OD spiders: Multiple spiders share the load, helping center the voice coil under high power and large excursions.
- Dual extra heavy duty interweaved tinsel lead wire: Reinforced wiring handles repeated flexing without impedance loss.
- Cast aluminum DC Tooled black frame / no invert mount: Stiff, rigid structure designed for reliable mounting in demanding installations.
- Large Neo Columns: Heat-dissipating structure aids sustained power handling and reduces thermal compression.
- Rubber mounting gasket: Improves sealing and reduces vibration transfer into the vehicle chassis.
- Direct Leads: Short, direct electrical path enhances power transfer and reduces inductance losses.
- 3.5" 8 layer hi-temp aluminum voice coil: High thermal capacity and strength for sustained, high-power performance.
- Power Handling RMS 3500W / Peak 7000W: Indicates substantial headroom for continuous and peak bass demands in a high-SPL build.
- Mounting Depth 12.75" / Mounting Hole Diameter 16.9" / Outside Diameter 18.5": Key dimensions to ensure proper fit in a large enclosure and compatible mounting.
- Voice Coil Diameter 3.5": Matches the 3.5" coil design across the line, supporting strong coupling to the cone.
- Displacement 0.26 ft³: Larger internal excursion capability translates to deeper bass in appropriate enclosures.
- Sd 1159 cm²: Cone area contributing to overall output per watt and low-frequency extension.
- Ohm Options d.7/d1/d2: Multiple impedance options to match amplifier and enclosure design.
- Suggested Ported Box 5.5 ft³: Recommended enclosure size for ported configurations at this 18" size for strong low-end output.
- Ref SPL @1 watt 85.74 dB: Sensitivity baseline indicating how efficiently the driver converts power into sound at a 1 W input.
In a serious automotive system, this 18" sub delivers deep, impactful bass with robust headroom, thanks to heat-management features and a high-power rating. It suits large-enclosure, high-SPL builds where a 5.5 ft³ ported box is recommended, delivering the low-end authority required for competition-grade or premium daily-driver installations.
