L166A woofer question

Bought a set of L166A in a package deal Sansui 9090 and a Dual 701 all is great shape in factory boxes. The JBl's have no woofers in them all others components original and intact. are there any good non JBL woofers to use in these or do I need to be patient and find the 122a-1's

Or what other JBL woofers work well in these cabinets that are more readily available

The JBL 128H or 128H-1 are the recommended replacements from JBL. They are an improvement. The H is white-faced and the H-1 is the more modern black-face commonly found in the 4412 and 4412A.
