Switching up the Game

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.


Go with the Flow

The Stadium’s voice coil significantly increases power handling and improves reliability by going with the flow—of air. The woofer’s motor channels air pumped by the cone movement past the voice coil, and the voice coil former exposes the coil’s inner and outer surfaces to the airflow. This aero-cooling design is unique among aftermarket subwoofers.

Perfect fit

The following review is for XMDFS121, which is a part of the bundle you are viewing.

I thought this box would be kinda bad when i purchased but its holding about 700+ watts at bay with the Nvx vsw dual 4 ohm sub. When i inspected the box before sub install I had more confidence with it. I did upgrade the terminal cup since i was running over 700+ watts to a 600 watt sub. Its holding up good so far and matches very well with the nvx vsw.

Decent for the price

The following review is for XMDFS121, which is a part of the bundle you are viewing.

Looks good, works good however the glue on the carpet could be better. It's been in my car for a few weeks now and I checked some things earlier and the carpet is already peeling.

Awesome

The following review is for Stadium 122SSI, which is a part of the bundle you are viewing.

I have these in a custom built box tuned down to 30 Hertz. The box just about took up the whole big trunk in the Cadillac. Pushing them with a BAMF 5000D. They sound absolutely amazing.

JBL Never Disappoints

The following review is for Stadium 122SSI, which is a part of the bundle you are viewing.

I’ve been a JBL fan for years, I have it all, from wireless headphones to 7.2 home theater systems and soundbars, so it’s no surprise that I went with the Stadium 12s for my build. I put one 12 in a custom box at first, sat in storage for 3 years before I finally took it back out, added a second 12 and hooked my NVX 1700.1 amp. This setup hits hard ???????????? well built subs, powerful, sound quality is top notch as usual, carbon fiber cones and factory surrounds are beautiful. Jbl really went in on this one. I’m curious about the Arena X 12s, maybe next year I’ll upgrade ???? don’t tell my wife.
