Here’s the original message I got from Brady http://www.youtube.com/sleeperawaken36
Hey Brian,
You might remember that I mentioned some time ago, that a good upgrade for your JRX115 cabs, would be to replace the compression driver with a Selenium D210Ti. They happen to be on sale now, as they are moving to a new 2008 model. They are selling for $31 each, and they are a drop in for your JRX115 cabs.

I know your JRX115 cabs already sound good, but these will make them sound better, so I am just passing this tip along. Why? For a couple of reasons.
1) Your JRX cabs have a frequency response of 50Hz -12.5KHz +/- 3dB. The JRX115 cabs have always been known to have really good bottom end for a single 15″ cab, but a little short on the top end. Dropping these in will change that to 50Hz - 20KHz +/- 3dB, giving you a LOT better top end, with less power to get it there.
2) The Selenium D210Ti is a better, cleaner sounding compression driver than the stock JBL compression driver in the JRX series as well. The JBL higher end compression drivers are a different story, but then they cost more than your speaker cabs & definitely mine…hehe (I would love to have some though 
Anyway, I’ve got two of these on their way to me now. They are a nice upgrade for my cabs as well, at only $31 a piece. I do know your JRX115 cabs sound great as is, but thought I’d pass along the tip for a nice upgrade if you are interested I’ll be doing a vid when I get mine in.
Hey, I’ve been getting a few new videos out lately, could you check them out? Hey, I’m still loving your vids Thanks
Brady

Hey Brian. I’ve been thinking about replacing the drivers in my Yamaha S12e speakers…if I get the right sized horn, would the D210Ti’s work well in them? I might get a new low driver.

i dont think it matters, providing you do it the same way around in both speakers so you dont get a polarity difference, or so thats what i was told

sorry, I don’t understand much English, so I did understand the name and the model of the new driver you use for your jbl, I only understand “selenium” but not wich model… Do you think this could be ok also for the jrx-112 (the difference should be 12″ woofer instead of 15″ like yours). Thanks.

I can definetly hear the difference.
But, only because the high driver of the replaced driver is pulling out the woofer…
Is there a filter inside the speaker?
Maybe it’s not specificly the driver… maybe it’s the filter.
Sorry bout my crappy english…

Even with the cheezy video recorder microphone, I can hear the difference. The new driver is more brighter, the highs are more detailed and clear. The stock ones just sound “muddy”. Hard to believe that comes standard with JBL products.
