Review: Best set of speakers to fit into and replace oem Subaru liberty GT my10 dash mid range speakers.
Review: Beautiful upgrade over my very old and crusty OEM speakers in my 2004 Honda Element EX. The sound is rich, warm, and well-balanced, just the way I like it, perfect for classical music, jazz, and crooners, which I listen to most. They also handle electronic music surprisingly well, and the bass is solid! I spent weeks searching for the right speakers, and these definitely do a fantastic job. At this price point, it’s hard to find better! Highly recommend!

2018年式マツダCX-5 BOSE仕様車のセンタースピーカー交換にこちらを使用しました。 音の輪郭がハッキリ違います。そのおかげで前方定位感も良くなりました。 外国産スピーカーは初めてでしたがなかなか繊細な音が出て大変満足でした。
