Review: Best OEM replacements - Best set of speakers to fit into and replace oem Subaru liberty GT my10 dash mid range speakers.
Review: Really Surprising for the Price Point - 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!
