JBL 4429, deep bass ?

Have a pair of 4429s. When they were new, they had very little bass below 50/60 Hz. Took a good year for the suspension to loosen up. Bass seams to be fairly flat into the 30s in my room. Anechoic response will always show a rolloff around a 100 Hz. Depends on the baffle loading. I have to agree with Dave_B. These are the best I have ever heard at my place. Talk about realism and detail, these have it in spades. My system consists of a Schiit YGGDRASIL feeding a Yamaha A-S3000 integrated amp. Balanced off course! The Schiit uses four medical converters - two per channel to feed the balanced outputs. Converters are guaranteed to be monotonic to 22bits. Put on Yanni "Live at the Acropolis" the other day. Had not heard it on this system. Good recording for being live. Sounded completely different then I remember it on my systems of the past. Wow. The harp sounds real and back in the distance. Dave_B, pick up the Schiit if you can. It is a serious converter, and the 4429s sound incredible with it.       

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.

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.

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.
