Little mistake with processing and limiting and the party could be over before it has started..

Some while ago we played around with amps being tested on some 21" reflex ones. We managed to put in more than 4kw (or even 5kw, do not have details in front of me)  into a listen 1600W AES 21" woofer.
Does it make any sense.. Hell no, for that perhaps 1 db extra in my opinion is does not make any sense.


Point is, it's not a 1000W at it's latest version. 2.5k input won't kill it as long as your setup is correct. You have had badly setup system or something else wrong with. Or have you seen anyone else complaining about the same issues here? There is loads and loads of TRS users here and they haven't had any of these issues you say you had.  Obviously it raises questions why you have had these issues, also considering that even 2.5k input won't damage the drivers and won't make cabinet rattle.

darkraver, Having read this thread, there are only 3 assumptions that can be made.

1. Your cabinets are damaged (dropped, crushed, water damaged, thermal shock, previous missuse).

2. You cabinets are badly modified or altered from original (or copies).

3. Despite 1000's of cabinets being made and loved by 100's of sound engineers who use them daily, they somehow don't know what they are doing/listening for but you do. 

You've already discounted 1 & 2 so that only leaves 3. You're either very unlucky or some kind of genius.

1. No, but some years old :)
2. No, unless the distributor did so. 
3. There are like 10.000 so called "sound engineers" that use Dap Audio and they like their stuff as well. 
Conclusion: I just do not like the 800 and 1000W versions. 

Based on that experience I would suggest to TS not to stare blind on TRS only.

Seems like a lot of bins to buy if they aren't any good..
Money can't buy you happiness, but it can allow you to be miserable in comfort.

Good reading should not be that difficult Wink
As said before, I do not own them, just so now and then I have to work with them.
I have my own stuff :)

But I sure will have a pic. of some TRS218 somewhere Clap

Indeed, not my idea.
Trying to update something in order to get a better performance is not my vision.
If I do not like something I never update :)

The 18s speakers were cheap to get and cheaper to get than the original 400W drivers.
Getting decent speakers and moderate prices is not that difficult if you have your connections.

I know this thread is a bit older but anyway just to let you know:
One of our customers put in the same 18s drivers as he was told by 18s that "these are specially designed for the TRS-218". LOL
Needless to say: He managed to kill 4 of them in no time - interestingly using XTI(4000) amps with "original Ohm settings" for his TRS as well.
The cones looked like they had been torn apart by a tornado.
He doesn't believe that his crappy amps and wrong settings in the processor cause that kind of damage.

Compared to that I have been running TRS-218 with Matrix and PKNC amps much larger than that (running XE4000 and 6000 at the moment) and _never_ ever killed a single 18" driver in them.
But then again I've never managed to kill a 12" Ohm driver in TRS-112 or 212 and I've been running them with loads of power indeed.

Does anyone know what the "S" version is on the BR218S?

Are they still a folded horn? To me "BR" means "bass reflex".
