Just got these home. The surrounds are newly changed, need to run in, the bass sounds a bit stiff. This is my first speaker with passive radiator. The Bass goes kinda deep. Not sure what is the spec of the L222.

1) Upon opening this thread, I see no L222's.

2) Upon entering my own home, I see no L222's either.

This is a very sad day.

I've run the LF section successfully as a sub.

There's a PR sub project to be made using the L22x as a model.

That belongs over in Technical , tho.

And I gotta read up some more, first.

Point is, bass is good.... :thmbsup:

The PR sub project using the LE14 and PR15C is ancient news G.T. and I hashed out for the final time in the late 80's. We abandoned it as a viable solution. You guys are naturally free to hash it all out again and I'm sure you'll post how splendiferous it is. :rotfl:

Nice examples of L222's ngccglp and John W! :yes:

Hey, could you point me to those threads... I've been busy lately and have missed a lot of the better ones, I'm sure. :blink:

What was deemed to be the fundamental shortcoming of the approach?

I am guessing that a LE14 subwoofer system would be better implemented using a ported alignment.

Just my guess of course.

In my opinion most woofer alignments are best not using a PR... I am not a fan of the "full" sound they tend to offer.

What was deemed to be the fundamental shortcoming of the approach?The JBL PR's were ancient by then and simply couldn't add any performance benefit to the 124/2203, LE14 and 136/2231/2235 that a properly designed ported system using those drivers was capable of. (The PR8 and PR10 had always been good matches for the LE8 and LE10 in small volumes). As Gordon has pointed out, there are far better PR's out there today and probably for a lot less money. I think the current price for a PR15C recone is pretty steep.

RonYes and the lower order the better. You may notice that JBL transducers tend to slip into quasi-third order alignments rather easily.

WidgetYes... one engineer described their character as "wooly".


Same thing with higher order assisted alignments such as the B380, B460 and 4645's using bump filters to create 5th and 6th order alignments. Yeah, they go real deep but they just don't sound real musical compared to lower order systems. They just don't. And some people won't listen to anything unless it's an acoustic suspension or infinite baffle design. Those types of systems usually swing too far the other way for my personal taste but some people swear by them.

So... its not the running in then, it is the characteristic of the PR sound. It sounds very different from my Altec A7 in the bass region. But I still won't say they are "wooly", bass notes articulation could be heard clearly. I think JBL tried hard to voice this speaker to sound like their studio monitors, incidentally setting the standard for much of Japanese 80s floorstanders in terms of look and sound.:D

But these babies need solid state amps (I'm using naim) to make you realise just how good the transient response of the LE14 is.
