These little speakers are absolutely fantasic with both quality construction and sound. I have purchased speakers from this manufacturer before and all are great. In my application however, the magnet was just slightly larger than i could use. I do highly recommend them if they fit into your configuration.

I used these speakers instead of the regular ones. Because the paper diffuser of the regular ones was destroyed by the sun. The mounting place did not fit exactly. Therefore, I had to use only two screws instead of four. But this is normal. Before buying, you need to know whether this speaker is suitable in terms of nominal resistance. So that the sound volume matches the other speakers in the cabin. I can't say anything exact about the frequency characteristics. Because I don't have the appropriate equipment. But to my ear, it's not bad. Especially for that kind of money.

So I bought the speaker for the center channel of a 2005 vw Touareg. It didn’t fit. But hopefully I can figure out somewhere to use it
