Dear all,

I'm restoring a pair of original JBL SR4726a speakers (2226G + 2447/2381). I took a look at the filters in the JBL tech sheet and compared them to the newer SR4726X. They are completely different!


The older SR4726a has a 4ohm woofer and the older topology with resistor based CD compensation and the newer SR4726X has an 8 ohm woofer and a much cleaner filter topology.

I happen to have 4, 8 and 16 ohm 2226's available so I wonder if someone on this fantastic forum would know if the difference between the filters in the older "a" version and "X" revision would make it worth to build new filters and swap the 2226G's for 2226H's.
All the best
