Can anyone describe the differences between the L150 and the L150A ? And are there appearence differences in the two models drivers? Which model is usually considered more desirable and why? Are they nothing more than a tall 116 or does the 150 offer distinct advantages that establishes them as a real player in the JBL catalogue? thanks.

The L150 was basically an L110 with a twelve-inch woofer and passive radiator in a 4 cu ft box instead of a ten-inch woofer in a 1.5 cu ft box.

The L150A was basically an L112 with a passive radiator and a 4 cu ft box for deeper bass. The L112 was roughly a 1.5 cubic foot box.

Yes, they are both real players.

I have both. L150A has a different top end and different crossover points but they both sound pretty good and they have real low end extension.

Thanks Allan, Are there visual differences in the two models drivers? And is it fair to say that one of the 150 pairs out performs the other? Or are they just a little different ?

Are there visual differences in the two models drivers? The L150A has the same 044 tweeter as the L96 and L112 so look for the aluminum frame with the silver screen over the diaphragm. The L150 uses the 033 so look for the black frame, no screen, and a black diaphragm. Or look in the library:

Correct me if I'm wrong, but I believe the L150 uses the 033 tweeter and the LE5-10 midrange and the L150A uses the 044 tweeter and the LE5-12 midrange. The midranges are acoustically the same the only difference between them is the bright brushed aluminum frame on the LE5-12 instead of the black brushed aluminum one on the LE5-10.

Late night brain fade. I probably meant to say same tweeter as the L166 but black and got sidetracked. Thanks for correcting my bad info! :)

It's not so late out here. That's why I was able to do the correction.;)

Of course if it's not the late hour, then it's one old age and then the memory goes.

If you have a line on either, get 'em! You'll be glad that you did. I really, really like my L150s.

At least I remember I have a pair of L150As in their original boxes, in the garage, waiting for me to get around to the quadruple re-surround job they're in need of. I guess on some level that's a good sign! ;)

One can look up the models I mentioned. One can also Google "JBL L150" and then select images to see all kinds of pictures.

Here are the network schematics:

Oh, contrere mone ami, you're one of my favorites...:D ; and to shift back to the topic, I do have a line on some L150s (not A models). They would need some veneer clean up, but not too bad, and the drivers and their function (xovers & pots) is reported to be trouble free. The game room I am setting up has L65s dedicated to one wall and I was thinking of putting the 150s on the opposite wall almost 17' away from each others pairs. Too ambitious, or go for it?

Go for it! I have a similar arrangement with L112 or L96 on one wall, facing a pair of L150A across about the same distance as your room, maybe a couple feet longer. I had the L220 in there for a couple of years but am moving the L150A's back in this weekend to replace the [sold] L220's. I normally listen to the larger fronts by themselves and only turn on the smaller pair on the other end of the room when I want it cranked really loud.

This is for gaming? Like using a joystick with a computer and a TV screen? Isn't that what Bose are for? ;)

Should image about like my car stereo. :D

Nice, I was thinking with the 2 pair, I could use relatively low gain on the volume and still do a nice job of filling the room with sound.:bouncy:

I mean if the truth really should be known, its probably an excuse to get the 150s. If it doesn't work, I'll pass them on. A game room TV, Stereo, and the obligatory pool table.

Well, my other option was to use the same configuration with a pair of Bose 501s and a pair of Klipsch La Scalas...

Do the L150 & L150A's have different power handling capacities, as the L110 & L110A's did? thanks

Not really, the L150 and L150A both used the SFG Ferrite 128H whereas the L110 used the alnico LE111A and the L110A used the SFG Ferrite LE111H. The ferrite motors had a bit higher power handling due to the increased heat sink capacity.

Something like that, lol... this room needs so much acoustic treatment before you could use it for critical listening, you wouldn't believe it. It's fairly large but too narrow in one dimension, too long in the other, wall full of windows on one long side facing a drywall expanse on the other, and vaulted hard ceilings too. It's somewhat listenable at low to moderate levels with either pair of speakers playing, particularly if you sit in the sweet spot. It moves up to "annoy the neighbors" SQ with both pairs on or with the level cranked up. Turn on the B380 and things really get ugly. Would be a great room for playing drunken billiards in, but someone would end up putting a cue through those windows every time.

Anyone have positive experience with the non-A model L150s. Are they noticeably diffcient whan compared to A models? Are they desirable or am I in for a bit of a let down?

L150s are one of my all time favorite speakers. They are forgiving of placement, amplification and source. You would have to work hard to make them not sound good at the very least.
