You know that the L100 Classic and the 4429 share the same woofer. One has a white damping material sprayed on the front. The other is sprayed on the back. Low end should be the same.
Well, the porting is different, the cabinets are different, and I don't know but wouldn't be surprised if they cross over differently.
Zowie. I would think the cabinet volumes are close. But you could research that. I have a plot of the response of the 4429s' in my listening room. I will look for it and submit it if I can find it. To my ears the 4429s' seem to dive into the 30 range. It took awhile before they went that low. Probably a year before the suspension loosened up. That woofer has a dual spider setup.
It does not look like I can insert the PDF file here. The rolloff starts at 40Hz, but judging from the file date the speakers were only a couple of months old. I know the bass improved quite a bit after a year.
Update!!  My 4429’s sound even better now...got some anticables involved which are by far the best cables I’ve owned (owned $20k speaker cables).  Coltrane LIVES!!  For the would be audio cognoscenti, they play with greater dynamic freedom, realistic visceral bass, extended non fatigue inducing high’s and wide soundstage the competes and in most cases beats my previous Wilson’s and B&W’s to name just 2.
