1. Продукт бүтүп калдыview

The JBL Arena series 12-inch (305mm) automotive subwoofer incorporates Selectable Smart Impedance (SSI) technology and features a design optimized for car audio applications. It utilizes light and agile 2/2.5-inch voice coils within a magnetic gap for linear control of cone excursion. The Symmetrical Field Geometry™ design contributes to linear cone travel and reduced distortion. Construction materials include a cast-aluminum frame, concave cone, nitrile butadiene rubber (NBR) surround, gold-plated speaker-terminal binding posts, a progressive spider, and a vented pole piece. This subwoofer is designed to handle peak power up to 2400 watts (with RMS ratings of 400/700/800 watts depending on model variant), with components engineered for voice coil cooling and sustained output.

Негизги өзгөчөлүктөрү

• Unrivaled power handling: Engineered for high power output, capable of handling up to 2400 watts peak power (400/700/800 watts RMS).
• Dual voice coil design: Features dual 2/2.5-inch voice coils suspended in separate magnetic gaps for linear cone control and reduced nonlinearities.
• Die-cast, vented aluminum frame: Provides significant venting and heatsink fins for enhanced power handling and maintains voice coil alignment.
• Composite paper full-edge subwoofer dust cap and cone: Utilizes lightweight and rigid composite paper for efficient air movement without flex or distortion.
• Grilles included.

• Алыстан күйгүзүү зымы: менен туташуу amplifier's remote turn-on input, typically from the head unit.
• Аудио киргизүү: туташтыруу amplifier's speaker output terminals to the subwoofer's gold-plated binding posts. Ensure correct polarity (+ to + and - to -). The dual voice coil design allows for various wiring configurations (series or parallel) to match the amplifier's impedance requirements. Consult a professional for optimal impedance matching.

4.3 Монтаждоо

The subwoofer is designed for flush mounting. Select a suitable enclosure (not included) that meets the manufacturer's recommended volume specifications for optimal acoustic performance. Secure the subwoofer firmly within the enclosure using appropriate hardware.

• Ensure the mounting location provides adequate clearance for the subwoofer's depth and allows for proper ventilation.
• Avoid mounting in locations exposed to excessive moisture or direct sunlight.

5. Операция

Once installed and connected to an amplifier, the subwoofer will reproduce low-frequency audio signals. Adjustments for bass level and crossover frequency are typically made on the connected ampкөтөргүч же баш бирдиги.

• Bass Volume Remote Control: Use the included bass volume remote control to adjust the subwoofer's output level conveniently from the driver's seat.
• Кроссовер орнотуулары: Төмөн өткөрүүчү чыпканы орнотуңуз amplifier to prevent higher frequencies from reaching the subwoofer, ensuring clean bass reproduction. A typical starting point is 80-100 Hz.
• Пайданы тууралоо: Carefully adjust the amplifier's gain setting to match the output of your head unit without introducing distortion.

6. Кароо жана тейлөө

• Тазалоо: Use a soft, dry cloth to clean the subwoofer cone and frame. Avoid using harsh chemicals or abrasive cleaners.
• Текшерүү: Periodically check all wiring connections for tightness and signs of corrosion. Inspect the subwoofer surround for any tears or damage.
