Smokin' JBL
« on: February 14, 2014, 12:27:37 PM »

I didn't go to this show, but a friend snapped some pics of Big Business playing The Mohawk in Austin last night (2/13). His caption: They were jamming so hard a speaker started to smoke!

If they'd point the speaker toward the audience instead of the ceiling, maybe they wouldn't have to run it so "hot".

Naw.  I suspect it's either the guitar tech or the monitor guy firing up a phatty.

If it were a new age band it would probably just be incense.

I have smoked many a JBL-and EV-and McCauley-and Fane and and and in my many years.

It is well into the hundreds.  That is exactly what got me into speaker reconing-to same me money on my own repairs--------------

You learn a lot from speaker failures-IF you pay attention.  But it still happens.

But it has little to do with what the band was actually doing on stage.

In all my years I've blown maybe 5-6 drivers. I guess you weren't paying too much attention. Shame on you Ivan, my respect-O-meter just dipped 1/2 point.

I "cut my teeth" doing metal and punk back in the 80's.

I was sending out 4 systems a night, with my guys and other guys operating them.

Sometimes it is hard to tell the difference between the "music" and distortion of the loudspeakers.

Of course there were some rap shows that also took out drivers.  It was my introduction into what happens when you use big power and sinewaves into drivers :(

Also back then drivers were not as robust as today.

If it makes you feel any better-it has been years since I have roasted a driver.

Pffft thats not a blown driver , THIS is a blown driver - jamming a voice coil in the gap of a JBL 15 so tightly from a combination of burning the coil and jumping the gap that the old coil / former couldn't be extracted and the entire speaker had to be thrown out.

Just busting chops Ivan. Got ya.
 
I think I've seen at least 100 or so blown Jensens though. Do they count as speakers?

Guitar speakers would be more a "voicer"-----------

Those photo's aren't much of a surprise to me.

We had a run where VRX 932 LF drivers were coming back blown up. In every instance it was not enough rig for the gig. The boxes are rated for quite a bit of power but they don't get that loud. The damage seemed to mostly occur when deployed as singles. Our boxes are passive and this would make sense as the system is at it's least sensitive and the amps make the most power per driver.

That was my thought when I saw the picture. the LF probably isn't designed to keep up with the HF since they expect you to use at least 2 together.
