we took the new v1200 loaded Hogs out last night, started with 2, ended with 1.

spent ages setting up a good gain structure before the gig, got it all sounding nice, went home and had my tea and came back to the gig, which kicked off at about 8.

went back to the gig, powered up the system and got cracking, for about 3 hours it was all good, getting loads of positive comments about the sound.

read into the T amp specs and it does say it will produce 2kw @8r in bridged mono, so after rog's comments about hanging an infinate 8 off them and throwing 2kw at each driver i decided even with chinese watts we had enough juice in the amps to give them plenty of clean power without clipping, limiters were set @ -15Db on the DCX with 35-80hz 48 butterworth x over, and the gains on the amps set to about 3 o clock (not very technical i know)

all seemed well, so i went out for a smoke with my mate, came back, and 1 bin had stopped working, no noise or cone movement, dead as a dodo.
.
checked everything, swapped the cable from the working bin, nothing. couldnt get to the driver as it was behind a grill, but i'm about 98% sure its dead.

as i wasnt in the room when it happened its hard to say what happened before the bin stopped working, but the bar manager didnt mention any distortion, or that the box sounded like it was about to blow, it just stopped working.....?

gonna pick up the system this morning and inspect the suspect driver, if it is blown i'm going to be pretty gutted, firstly because of the cost factor, and secondly, after running fanes for years and moving up to the big boys driver, i did hope they would be able to take more power than we were giving them last night without sh*tting themselves on their first outing.

so anyone know what the damage is for a v1200 recone? or am i the first to need one?
if i am the first, maybe void will send me one as a prize!

Gutted man, I hate killing drivers, feel for your loss.

My only thoughts are limiting / attenuator setting on the proline.

The prolines have very sensitive inputs, I usually find I have to turn the limiter on the DCX right down as low as it will go with the amp set at fully open, this prevents any cliping (in most situations!).

Maybe some cheeky bugger played with the amp while you were outside? Have you anything like an AVC2 in the chain before the DCX?

Of course I'm gunna also say... Should have gone for the real daddy - the PD1850 instead of the P.Audio ;)

i wasnt a proline, 2 T amp 2400's in bridge mode, 1 on each bin.

dispite the fact that T amps get totally slated on here, i'm happy running them for the time being, there was also a small (5-6kw) in house martin audio w3 system being powered by crest amps, which was running before i got there, and when i switched our rig on the output from our "DIY boxes, 'crappy' T amps & vintage macrotechs" made the matrin rig look like a joke....got loads of positive comments from punters and dj's for the bass that was being churned out.

dont get me wrong, i'm happy with our purchase, the bass is very defined, and the output from 2 bins is pretty damn impressive, last night was a bit of a learning curve to see how far we could push the boxes, and now we know!!
and i think even the mighty 1850 would have been on its knee's with the kind of punishment the V-1200's were taking last night.... straight up relentless dubstep pressure! i've never seen an 18" driver in action quite like a V-1200, its very impressive indeed.

gonna pick the gear up shortly so i'll know for sure what the cause of death was in a few hours.

Do the T-amps get a slating? I quite like the 2400 of Florians, seams to be all round better than the EP2500, power / sound and good build quality for a "low cost" amp.

2k into 1 driver on dubstep is pretty hardcore.

T-amp? slating? Talk to heathrom B line!

rog said it would eat up 2k from an inf 8 so i thought it would be ok on the T amp, which probably puts out considerably less in the bass end. it wasnt going balls to the wall either, gains were set at about 3 o clock so there was more juice in the tanks, all the levels were looking good, nothing had been turned up while i had been gone...its a real mystery.

although highly unlikely, there is a massive part of me that hopes that a wire has come loose inside the box, when i put my head down near the mouth, the air movement going on was quite frightening....so i'm praying a shoddy bit of soldering will save the day!

So the Void V18-1200 is a P-audio OEM then?  Or is it just a P-audio sourced chassis?

V18-1200 won't take 2kw of sub heavy material. And I said it before in Scoop forum and was crucified. It wont take 1200W of it either. Its not very sensitive, so it takes more power to reach the same SPL as 1850, but by the time you've got it there, its about to blow.

You're not the first to blow V18-1200s, ask Marvin.Wink
