JBL Stage 122D 12" Dual Voice Coil Car Subwoofer
Description
Description
The JBL Stage 122D 12" Dual Voice Coil Car Subwoofer delivers 250W RMS / 1,000W peak power with a dual voice coil (DVC) design that gives you flexible 2-ohm or 8-ohm wiring configurations to match your amplifier's optimal output impedance. The step-up from the Stage 122, the 122D adds DVC wiring flexibility while maintaining the same individually voiced JBL signature bass character, polypropylene cone, and hi-roll rubber surround.
The Stage 122D is built around a polypropylene cone — lightweight and rigid for accurate, low-distortion bass reproduction with frequency response reaching down to 34Hz. The hi-roll rubber surround maximizes cone excursion for deep, punchy bass while maintaining long-term durability. The 2" (50.8mm) dual voice coil handles the 250W RMS thermal load efficiently and provides wiring flexibility: wire the coils in parallel for 2 ohms to maximize power output from a high-current amplifier, or in series for 8 ohms for cleaner, more efficient operation with amplifiers that perform best at higher impedance loads. Sensitivity reaches 91dB at 2.83V for strong output efficiency. Frequency response spans 34Hz to 200Hz. Each Stage 122D is individually voiced by JBL transducer experts to ensure consistent sonic character across the lineup.
Pair the Stage 122D with a mono amplifier rated 150–250W RMS at your chosen impedance. Wire the coils in parallel for 2 ohms to maximize power output, or in series for 8 ohms for cleaner operation. Use a ported enclosure tuned to 35–40Hz for maximum output, or a sealed enclosure for tighter, more accurate bass. The DVC design also allows bridging two amplifier channels across the coils for unique system configurations — contact us at Trinity Car Audio for wiring guidance.
Why Choose the JBL Stage 122D?
- Dual Voice Coil (DVC) Design: Wire in parallel for 2 ohms (maximum power) or in series for 8 ohms (cleaner operation) — flexible impedance matching for virtually any amplifier.
- Individually Voiced by JBL Transducer Experts: Each unit is tuned to deliver consistent JBL signature bass character — not just spec-matched, but sonically validated.
- Polypropylene Cone: Lightweight and rigid for accurate, low-distortion bass reproduction down to 34Hz.
- Hi-Roll Rubber Surround: Maximizes cone excursion for deep, punchy bass while maintaining long-term durability.
- 91dB Sensitivity: Efficient design delivers strong bass output without taxing your amplifier.
- 250W RMS / 1,000W Peak Power Handling: Handles real-world amplifier power without distortion or thermal compression.
- 34Hz – 200Hz Frequency Response: Deep sub-bass extension to upper bass punch — full subwoofer bandwidth coverage.
- Step-Up from Stage 122: All the Stage 122 sonic character with the added flexibility of DVC wiring — more amplifier compatibility options.
Amplifier & Enclosure Recommendations
Pair the Stage 122D with a mono amplifier rated 150–250W RMS at your chosen impedance. Wire the coils in parallel for 2 ohms to maximize power output, or in series for 8 ohms for cleaner operation with amplifiers that perform best at higher impedance. For enclosures: a ported box tuned to 35–40Hz maximizes output for hip-hop, EDM, and bass-heavy music. A sealed enclosure delivers tighter, more accurate bass for rock, jazz, and everyday listening. Set your amplifier's low-pass crossover at 80Hz and subsonic filter at 30Hz for ported enclosures. Use 8 AWG or heavier speaker wire from amp to sub, and 4-gauge power and ground wire to your amplifier.

Frequently Asked Questions
Q: What's the difference between the Stage 122 and the Stage 122D?
A: The Stage 122 is a single voice coil (SVC) at 4 ohms — simple, straightforward wiring. The Stage 122D is a dual voice coil (DVC) that wires to 2 ohms (parallel) or 8 ohms (series), giving you more amplifier compatibility options. Both share the same cone, surround, power handling, and JBL-voiced sonic character. Choose the 122D if you need impedance flexibility or want to bridge two amp channels across the coils.
Q: Should I wire the Stage 122D to 2 ohms or 8 ohms?
A: Wire to 2 ohms (coils in parallel) to maximize power output from a high-current amplifier. Wire to 8 ohms (coils in series) for cleaner, more efficient operation with amplifiers that perform best at higher impedance loads. Contact us at Trinity Car Audio and we'll recommend the right configuration for your specific amplifier.
Q: What amplifier pairs best with the Stage 122D?
A: A mono amplifier rated 150–250W RMS at your chosen impedance is ideal. Contact us at Trinity Car Audio for a specific amp recommendation based on your system goals and wiring configuration.
Q: What enclosure type should I use with the Stage 122D?
A: A ported enclosure tuned to 35–40Hz maximizes output for bass-heavy music. A sealed enclosure delivers tighter, more accurate bass for everyday listening. Contact us at Trinity Car Audio for specific enclosure volume and tuning recommendations for your vehicle.
