Well TJ, your work isn't done yet. There are atleast 2 more companies from Brazil to rep. What are you gonna do with all that new green and yellow clothing you bought, lol?

Gr8 amp anyway
I can said to you what is public . In the power supplier we changed the IRFP2907 by other kind and now we rasp the label in order to create more difficulties to other developers . In the amplifier section we have the IRFP90N20D for 7K2,9K2 and 11K2. In the case of 14K2 we are using IRFP4668. About secondary voltage : 190V at 12,6 VDC

You can gather some time between making all those products and start your answers right now telling the Audio forum WHY you say that this amplifier can make 11500W in 2 ohms if the maximum voltage is 119.57V?
Because with that voltage the max is 7150W. [/QB]
We are saying in our website :
a) WRMS Power (1 ohm) to 13.8 V: 16.500 Watts b) WRMS Power (2 ohms) to 13.8 V: 11.100 Watts c) WRMS power (4 ohms) to 13.8 V: 6.200 Watts d) WRMS Power (1 ohm) to 12.6 V: 14.200 Watts e) WRMS Power (2 ohms) to 12.6 V: 9.500 Watts f) WRMS power (4 ohms) to 12.6 V: 5.200 Watts
Remember that 119,57Vrms is only for condition d) . This is the RMS voltage over the load. Frequently SOUNDIGITAL says that their amplifiers have regulated power supplier and STETSOM doesn't have . The advantage of non regulated power supplier is that you can increase the voltage to 13,8V and get 16.600 Watts in 1 Ohm because the internal voltage is not more 190V . If the SOUNDIGITAL has one regulated power supplier , the internal voltage is the same in both situation ( 12,6V and 13,8V). So, how the power suppliers of STETSOM amplifiers are not regulated , then in 12,6V at 2 ohms , the internal voltage will increase from 190 V to 209 V and the internal current get down also and it decreases the losses from 11% to about 7% . So , 209V - 7% => 194,3V/1,41 => 137,8 Vrms . So, 137,8*137,8/2 => 9.494 Watts . It is exactly the item e)

Why you say 16500W at 1 ohm in 13.8V if for that you would need 128.5Vrms on the output?
Because the power supplier of our amplifiers are not regulated . When , you change from 12,6V to 13,8V at 1 ohm , the internal 190V change also to 203,6V , but in this case we have losses of about 11% . So , 203,6V -11% = 181,18V. This value / 1,41 => 128,5 Vrms over the load.

Oh no, was one 12kD that had a 16V wire accidentally touching on its heatsink messing one pre-driver making it to deliver wrong phase to the sub, not DC but damage anyways. We only discovered after lots of damage on subs.
EDIT: The amp is fine, the problem was not related to the amp.

BTW Murilo - why Yr amps (Stetsom too) dont have any relay on output ?? Its not gona cost U fortune - its just relay(s), U already have uC onboard which could drive them up, doesnt it simple as tht ??
Battle of two most powerfull companies against eachother gettin louder with every single kW more - GuYs dont Ya think its enaf ?? I just remind U - U BOTH DOIN VERY GOoOD JOB, so STFUp please :]
Murilo we all know that Yr math is in good "shape" so just leave it and start comparing mesured results, and wht is more important... FINAL dB's
All bests.

Hello Mark, both Stetsom and SD solved the thump problem on their designs, not requiring a relay to cut the speaker line from the residual voltage provenient from the output wrong offset.

I like these healthy arguments between companies. This is just helping to push the envelope for bigger and better things.
Now I wish alternator companies wouldn't be so nice to each other, then maybe they would come out with a 400+ amp alt.

I'm sure you can get bigger then 400A, from some truck[real ones], but don't know where you would put one
Anyway, myself don't care how much one amp puts out, or if other is 0.3dB louder, you can't even hear that! For me, it comes down to šroce/preformance, rather have 10kw at "low" price, then 12kw... it won't make that much of a diffrence on music

No what it comes down to is customer services and good hospitality.
A strong corp that is willing to back and support there help and let them get the product out to the industry at a fair margin to all with equal pricing for everyone not just who you feel fit to get the job done.
Also some one that sticks to there own and don't care what others are doing cause they know what they have is a good product and will stick by it and every one that uses it.
A corp that is out for you the consumer to help the industry grow and learn for past mistakes.
The main probe is he says she says. but what it all comes down to price warranty will ya stick by it how dose it perform like ya say it dose and will it work for ya and most of all are they going to be there for ya when it breaks and how fair are they to every one. Not just Me.
if you cant do any of the above then you should no be in business. why cause you wont last long in the industry ask the others that made these simple mistakes. then look at though's that have grown and prospered and learn.
All bashing dose is make you look like the ass buy you all ready know you are so why stop on my part you make the bed you lay in so lay in it.
