They work really well; this is the third time I've bought them, and I'm very surprised by the quality of sound they have.
1 of the speakers came a bit bent but everything else seems ok and i tested them and their full range
The speaker fits into the JBL speaker.
They sound very good and have a lot of power for their size.
