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.\u003c\/p\u003e\n\n\u003cp\u003eThe Stage 122D is built around a \u003cstrong\u003epolypropylene cone\u003c\/strong\u003e — lightweight and rigid for accurate, low-distortion bass reproduction with frequency response reaching down to 34Hz. The \u003cstrong\u003ehi-roll rubber surround\u003c\/strong\u003e maximizes cone excursion for deep, punchy bass while maintaining long-term durability. The \u003cstrong\u003e2\" (50.8mm) dual voice coil\u003c\/strong\u003e handles the 250W RMS thermal load efficiently and provides wiring flexibility: wire the coils in \u003cstrong\u003eparallel for 2 ohms\u003c\/strong\u003e to maximize power output from a high-current amplifier, or in \u003cstrong\u003eseries for 8 ohms\u003c\/strong\u003e 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 \u003cstrong\u003eindividually voiced by JBL transducer experts\u003c\/strong\u003e to ensure consistent sonic character across the lineup.\u003c\/p\u003e\n\n\u003cp\u003ePair 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.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Choose the JBL Stage 122D?\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Voice Coil (DVC) Design:\u003c\/strong\u003e Wire in parallel for 2 ohms (maximum power) or in series for 8 ohms (cleaner operation) — flexible impedance matching for virtually any amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndividually Voiced by JBL Transducer Experts:\u003c\/strong\u003e Each unit is tuned to deliver consistent JBL signature bass character — not just spec-matched, but sonically validated.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolypropylene Cone:\u003c\/strong\u003e Lightweight and rigid for accurate, low-distortion bass reproduction down to 34Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHi-Roll Rubber Surround:\u003c\/strong\u003e Maximizes cone excursion for deep, punchy bass while maintaining long-term durability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e91dB Sensitivity:\u003c\/strong\u003e Efficient design delivers strong bass output without taxing your amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e250W RMS \/ 1,000W Peak Power Handling:\u003c\/strong\u003e Handles real-world amplifier power without distortion or thermal compression.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e34Hz – 200Hz Frequency Response:\u003c\/strong\u003e Deep sub-bass extension to upper bass punch — full subwoofer bandwidth coverage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStep-Up from Stage 122:\u003c\/strong\u003e All the Stage 122 sonic character with the added flexibility of DVC wiring — more amplifier compatibility options.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eAmplifier \u0026amp; Enclosure Recommendations\u003c\/h2\u003e\n\u003cp\u003ePair the Stage 122D with a mono amplifier rated 150–250W RMS at your chosen 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.\u003c\/p\u003e\n\n\u003ch2\u003eFull Specifications\u003c\/h2\u003e\n\u003cdiv style=\"overflow-x:auto;\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eJBL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eStage 122D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize\u003c\/td\u003e\n\u003ctd\u003e12\" (300mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Handling (RMS)\u003c\/td\u003e\n\u003ctd\u003e250W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Handling (Peak)\u003c\/td\u003e\n\u003ctd\u003e1,000W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensitivity (@ 2.83V\/1m)\u003c\/td\u003e\n\u003ctd\u003e91dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Response\u003c\/td\u003e\n\u003ctd\u003e34Hz – 200Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoice Coil\u003c\/td\u003e\n\u003ctd\u003eDual Voice Coil (DVC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImpedance (Parallel)\u003c\/td\u003e\n\u003ctd\u003e2 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImpedance (Series)\u003c\/td\u003e\n\u003ctd\u003e8 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoice Coil Diameter\u003c\/td\u003e\n\u003ctd\u003e2\" (50.8mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCone Material\u003c\/td\u003e\n\u003ctd\u003ePolypropylene\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSurround Material\u003c\/td\u003e\n\u003ctd\u003eHi-Roll Rubber\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e4.5 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What's the difference between the Stage 122 and the Stage 122D?\u003c\/strong\u003e\u003cbr\u003eA: 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Should I wire the Stage 122D to 2 ohms or 8 ohms?\u003c\/strong\u003e\u003cbr\u003eA: 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.
