JBL Stage 1 41F 4インチ 2ウェイ コアキシャル カードアスピーカー 25W RMS ペア

These 4-inch coaxials sit perfectly in my factory dash slots and the sound is noticeably clearer than the stock paper cones. I drove with them for a week and the midrange voices come through without any harshness.

I was surprised how much cleaner these 4-inch speakers sound compared to the factory ones—the midrange really comes through without distortion. They survived a few freezing nights in my garage before installation, so that rugged testing seems legit.

Installed these in my truck doors over the weekend and the difference is night and day. The environmental testing they mention must be real because they’ve handled a few hot days already without any distortion, and the 25w RMS is plenty for my head unit.
