Pros & Cons
👍 Pros
- 15-inch cone diameter moves significant air volume for deep, impactful low-frequency output — well suited for high-output car audio builds.
- Dual Voice Coil design provides wiring flexibility, allowing 4-ohm series or 1-ohm parallel configurations to match a wide range of amplifiers.
- High Roll Foam Surround supports long excursion travel for high-volume bass output without mechanical limitation.
- Advanced Air Flow Cooling System extends voice coil thermal tolerance for sustained high-power sessions.
- Competition-grade pressed paper cone provides a balance of rigidity and damping appropriate for bass reproduction at high SPL levels.
👎 Cons
- Gravity does not publish an RMS power rating — the 3,500-watt figure is peak only, making it difficult to properly match amplifier power without additional research.
- At 15 inches, this subwoofer requires substantial enclosure volume, which may be a packaging challenge in smaller vehicles.
- 85dB sensitivity is on the lower end for a competition subwoofer — you will need more amplifier power to achieve high SPL output compared to more sensitive drivers.
- No Thiele-Small parameters or enclosure recommendations are provided, complicating proper box design for optimal performance.
Frequently Asked Questions
What does 2 Ohm DVC mean for how I wire this subwoofer?
DVC stands for Dual Voice Coil — the GW15D2 has two independent voice coils, each rated at 2 ohms. You can wire them in series (4 ohms total) for a stable, easier-to-drive load, or in parallel (1 ohm total) for maximum power draw from a compatible amplifier. The configuration you choose depends on your amplifier's stable ohm rating.
How much amplifier power do I actually need to drive this subwoofer properly?
The GW15D2 is rated at 3,500 watts peak. Peak ratings represent the maximum instantaneous power a driver can handle briefly — not the sustained RMS power it should be driven at. Match your amplifier's RMS output to the subwoofer's RMS power handling specification, which Gravity does not explicitly list here. Overpowering or severely underpowering a subwoofer long-term causes thermal damage.
What frequency range does this subwoofer cover?
The GW15D2 covers 30–500Hz, which encompasses the full bass range from deep sub-bass through upper bass. In a car audio system, a subwoofer is typically crossed over below 80–120Hz — the upper range of the spec allows flexibility in system tuning but you'd cross it over significantly below the 500Hz ceiling.
What does the Advanced Air Flow Cooling System do for this subwoofer's performance?
The cooling system helps dissipate heat from the voice coil during high-power, sustained operation. Heat is the primary cause of voice coil failure under load — better thermal management means the subwoofer can sustain higher power levels for longer without damage, particularly during extended listening sessions or competition use.
What enclosure type works best with this subwoofer?
Gravity does not specify recommended enclosure volume or type for the GW15D2. For a 15-inch competition-grade subwoofer, ported (vented) enclosures typically maximize low-frequency output, while sealed enclosures provide tighter, more accurate bass. Consult Thiele-Small parameters for precise enclosure design, or use manufacturer-recommended box specifications if available.
