## Overview

The JBL Stadium 122SSI is a high-performance 12-inch car subwoofer delivering 500W RMS and 1500W peak power. Featuring Selectable Smart Impedance (2 or 4 ohms), an aero-cooled oversized 2-inch voice coil, and premium push terminals for efficient power transfer, it offers customizable, reliable, and powerful bass performance designed for audiophiles who demand uncompromised sound quality on the road.

## Description

A subwoofer that puts you in the driver’s seat: JBL believes sound quality should never be compromised and the Stadium subwoofers make sure you don’t have to compromise flexibility, either. That’s because these high-performance subwoofers feature SSI™ (Selectable Smart Impedance), an exclusive impedance switch that lets you select the optimum impedance—2 or 4 ohms—providing multiple system configurations and flexibility. A special aero-cooling design keeps the voice coil cool even at high output levels. This feature coupled with oversized voice coils increases power handling and ensures long term reliability. More power, more reliability, more flexibility—and no compromises. When you’re ready to step up, Stadium is your subwoofer

## Features

- SSI (Selectable Smart Impedance): Stadium subwoofers feature a dual impedance switch that lets you choose either load impedance option. This allows for a variety of system configurations when using one subwoofer or multiple.
- Aero-cooled voice coil: The Stadium’s voice coil increases power and improves reliability. The woofer’s motor channels are air pumped by the cone movement past the voice coil, and the voice coil exposes the coil’s inner and outer surfaces to the airflow.
- Oversized voice coil: The 2” voice coil proves you don’t have to be a heavyweight to pack a punch. It handles more power than conventional two-inch voice coils, yet it’s lighter than 4” voice coils. It strikes a balance between thermal power and low mass.
- Premium integrated push terminals: Power is the lifeblood of any subwoofer. The terminals on the Stadium subwoofers accommodates 8 AWG wire (8.37mm2 cross section), which transfers low-resistance, low-loss power to the woofer, even over long wire runs.
