A New big boy amp coming to the market????

[DUMPED 10+ year member]

I seen a pic of there 10k.Looked pretty impressive.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

10K is old news..15K is on it's way..

you can thank me later..

the 12K you guys are refering to

How many watts RMS "continuous" is this beast?? Not 8,000. Thats for sure. Maybe "bursts" but not continuously.

Those Switching Powers Supply cores are only good to maybe 1,000 watts each.

And there are 6? So??? The other 2 cores our output inductors for what is known as an "anti-aliasing filter".

Basically a 3 pole filter in the output stage to filter out the "hash (garbage) at slightly below switching frequencies.

Otherwise there would be just ugly white noise coming out the speaker leads.

And I counted 12 devices per side for switchers. Even if they are 70 amp continuous current (like an IRFZ48 device)

that is 840 amps of current , or about 7,000 watts.

And an even BIGGER questions is:

How do they PULL over 800 amps of current thru 1/8 thick PC board? And what gauge wire will be necessary?? Its gonna take WAY more then those "wussy" buss bars, that is for sure.

Hmmm???

And it doesn't matter what they say (or any other amp manufacturer), an 8,000 watt amplifier WILL pull 933 amps.

NO MATTER WATT!! Its Physics (not my fault)..assuming it really makes 8000 watts RMS .

Which is 89.5 volts out at the speakers (1 ohm)

Amp looks good, but will NOT be reliable. Short term, sure. Long term...not a chance in hell.

The stetsom amps were tested to be louder.

The internal connections are pretty sweet too.

Whoa! It is NOT possible that this amp swung 130 volts AC out!

Do the math, that is 130 times 130 divided by impedance (even if you use 1) that is 16.900 watts.

Smoking CRACK!!! Look at the devices. 16 FETS (bottom of picture) only 8 are on at any time,

so 8 times 70 amps (assuming IRFZ48's) and that is 560 amps of MAX current draw.

4 cores, the input connections, the "soldered" up PC traces.

16,900 watts or 13,000 watts is 1971 amps and 1516 amps respectively of full power current draw.

Thru that "nut and bolt" connection? Say what?? SMOKING CRACK!!!!!!

I do applaud them for using meters (good ones too!) But no O'scope and no test conditions ,

like what was the load? what kind of load? (meaning speakers or load resistors).

Test tone? All bits high (0dB) What??

Have you guys ever seen 12,000 watts of load resistors!! Neither have I and I can tell you it would be BIG!!!!

And I have seen a LOT of test setups. No one I know (other than Audison in Italy, Kicker and Rockford)

could even power up 13,000 watts of amplifier to test it.

Reality test here folks!!!

I know of two places... //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

here in North America..

 

[audioatg 10+ year member]

Arent there already some small tests done by the guy who is selling them on dbdrag forum... But no one in the US has actaully tested it yet. As far as what Im reading on the dbdrag forum.

 

[adam212 10+ year member]

heres a 15000 watt amp

Neither Rockford nor Kicker (in North America) have a 1500 amp continuous rated AC to DC power supply. Since I know these guys on a personal level (party at CES with them ever year for 15 yrs) Nor 13,000 watts of DALE power resistors.

So my guess is that this is "burped" 13,000 watts for a Milli second.

Whoopee, who cares, lightning strikes in the dark stuff.

Meaning 13,000 watts of pure square waves. Basically all we are seeing is the rail voltages of the Switching supply

Below is an Audison LRx1.2K 3,200 watts CONTINUOUS into 1 ohm. In the power supply there are 2 pieces of copper one on top, one underneath that cover the ENTIRE power supply area (about the size of a girls hand print) so that the needed 373 amps of current can flow safely...and continuously.

Under the switching FETS are thin ceramic plates to better transfer the heat off the transistors. each device is clipped down with spring type clips.

Thats how it is done for real. It ain't cheap, but it is "da kind" way. (and retails for $2,000.00) And not that big 22" X 8" X 2.25".

of the two places I'm refering to..

one of them is in Toronto and the other is in Arizona if memory serves me correct.

 

[CarAudioGuru 10+ year member]

Arizona? where I live //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Cogent Audio Labs (Gary Springgay) - Nope, 300 amp power supply (been to his lab a couple times) Big ass power supply! And he is a great tester too (use to do all Rockford's in house testing)

Toronto? Don't have a clue....

Nobody is really set up for this kind of tests expect maybe Crown in Elkhart Indiana. Big ass pro sound guys as they have built 10K Pro amps for years.

And they won't have the DC power supplies. it would have to be all battery. Which is OK.

And they would laugh at all these amplifiers (except maybe the Audison LRx 1.2K)

Would be some fun testing for sure. But the power ratings would not be what is being stated on these forums. That I can guarantee.

you're correct on him being one person. From what I recall he is also increasing

his power supply capability as well.

the other location is a facility in Toronto which has already tested some

of the largest Car Audio amplifiers in the industry as well. This particular facility tested the Maxximus as well with amazing results.

As for power supply they used a combination of batteries and power supplies in order to provide the sufficient voltage neccessary.

As for creating the appropriate loads they have an AMPLE supply of conductors neccessary to obtain the particular impedance as well.
