RetroSound R-507N 5x7インチ シングルトライアックス スピーカー 40W RMS

The 40w RMS handling gives these 5x7s a clean punch even with the windows down. Installed them in my classic car and the dual voice coils really opened up the soundstage compared to the old single-coil speakers.

Installed these in my old truck’s doors to replace blown originals, and the dual voice coil gives a really wide soundstage—way better separation than I expected from a single speaker. The 40w RMS handles plenty of volume without distortion, even at highway speeds.

The dual voice coil design really lets me dial in the soundstage in my truck cab, and midrange vocals come through crystal clear even at highway volume. Hooked these up to my head unit yesterday and the 40w RMS handling keeps things punchy without any distortion.
