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.

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.
