My recommendation would be the L150, but I am somewhat biased. I really love the 033 tweeter. It is a soft-dome that is very easy to listen to. It's not as bright or in-your-face as later metal dome tweeters such as the 035Ti, but doesn't sound like it's leaving anything out either. It doesn't have any of the maintenance needs that the 035ti has either, such as deteriorating foam under the dome turning into goo and clogging up the voice coil gap. If an 033 ever fails, the cheaper and easier-to-find 034 is semi-compatible. The 034 is a direct fit but uses a plastic frame whereas the 033 uses a metal frame. The problem being that air pressure inside the cabinet will press on the tweeter from behind and cause the plastic frame of the 034 to vibrate almost like a 2nd mini passive-radiator. I have a pair of 034 tweeters that I bought just to test with and that is what I found. I still keep them as my backups and if I ever need to use them I will find a way to reinforce the plastic frame or perhaps build a small sealed compartment behind the tweeter.
The LE5-10 mid-range is very nice, no complaints. I think it's maybe a small step down from the newer 104H-2 but I've never felt like it was holding anything back.
The woofer system in the L150 is probably my favorite part about the L150. The 128H woofer is a fantastic woofer, acoustically identical to the black-cone 128H-1 in the 4412A, which was a very nice Studio Monitor that JBL continued to sell well into the 21st century (Shows you how much faith JBL had in the 128H). Really it just sounds beautiful and is probably my favorite JBL 12" woofer.
It can handle plenty of bass.
The L150 uses a passive radiator which serves the same function as a port does in other speakers but has a few extra benefits. You can tune the bass response of your speakers using the passive radiator. This is done via
mass rings. Adjusting the number of mass rings on the passive radiator has the same effect as shortening or lengthening the port tube in a ported speaker, but whereas adjusting a port tube is a cumbersome process, adjusting the mass rings is quick, easy, fully reversible, and something that is fun to tinker with. The passive radiator also gives the bass a very special texture, that is distinct from what you get with a ported system. It's difficult to describe using adjectives that are actually meaningful, but it makes the bass sound very smooth without taking anything away from how impactful the bass is.
I'm not sure about the "minimum wattage" of the L150 but 85WPC should be plenty unless you are
really pushing them hard. I power mine with 700wpc but really it's rare that I need more than 100.
I notice that the 4410 is also on your list. A very nice speaker for sure, just keep in mind that it is a Studio Monitor (as opposed to a Control Monitor, such as the 4312, or a speaker designed for home usage, such as the L150). Studio Monitors are great, even for home usage, just keep in mind that they are designed with a response that is as flat as possible. If you value accuracy above all else, that can be a good thing. When it just comes to having fun and enjoying the music however, they can sometimes come off as a bit bland and boring. Of course you can always compensate for that to an extent, if you wanted, using EQ or tone controls. I have a pair of 4412 Studio Monitors, and while I do like them a lot and appreciate what they are good at, in the end they are probably my least favorite out of my 4 main JBLs (L150, L100T, L5, 4412).
