I have some questions about the JBL 2226H drivers that i have recently purchased.
There are quite a number of small ripples at the back of the woofer as you can see from the picture attached. The previous owner told me that it is not a reconed speaker, all original.
Any idea what caused the small ripples at the back of the woofer?
When i use a meter to measure the impedance of the speakers, it read 5.6 ohms on both the speakers. Is it consider too low? will the impedance drop again with age?
