No, it's really not.
They use different midrange drivers (4411 uses LE5-9, L112 uses LE5-12).
There are considerable differences in the crossover and voicing, with the L112 having more consumer voicing and the 4411 having a more flat response.
The 4411 is designed for horizontal orientation, while the L112 is designed for vertical orientation.
Neither is bad, but they do have noticeable differences. The 4410, 4411, 4412, 4412A all have a very flat response, almost to the point of being boring. That's not a bad thing, as that is exactly how they were designed to sound. But if you are looking for more of the classic consumer-oriented JBL sound then one of those Studio monitors is probably not what you are looking for.
Only interested in bookshelf speakers, no floor standers. Already own JBL L100's and JBL L36's which I enjoy, just thinking about trying something different. One of my thoughts was JBL L112's which I've never heard but have read they are great sounding speakers.
It's hard to go wrong with the L112. Great drivers all around. The 128H woofer is fantastic and the 044 tweeter is both smooth and accurate, and without the foam plug issues that affect the later Titanium-dome tweeters.
If you are interested in something newer, you might check out the JBL 530. They are actually on sale at the moment. The compression driver and waveguide is very nice, and if you are looking for something "different" than your L100 and L36, these definitely qualify:
