A world of difference
Just installed two sets into my '06 Ford Focus ZX5. With only the factory radio/cd unit, these speakers are performing extremely well and they are not broken in yet. They are efficient (92db sensitivity), the bass is tight and the treble is outstanding. A little weak in the midrange, but for the money, I am completly satisfied with the performance of these speakers. Tell a friend, if they are looking for speakers to replace their factory speakers and they are on a budget, these are the speakers for them!
