new rf amps

as anybody heard about the new RF amps. i heard their a 15kw amp. but i dont know just wondering, and i know they had them at CES this year

$19,999 not for everyone.

wow..well i heard christpohe of Cn Sounds is getting a couple.and i heard they are huge

I think that is burst power

It's not "really" a 15kw RMS amplifier.

More like a 4kw amplifier with 15kw of "burst power".

I, for one, am not all that impressed with it or the technology.

hey the link isnt working man..

but yea thats what i kinda figured is a burst...

Here is a link to it.

Rockford mentions nothing of this "burst." There is a thread in RF's forums where the main developer of the amp talks about it and its new technology. I can't wait for them to apply this technology to all of their amps.

3750 W x 4 @ 0.5 Ohm RMS //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

And only a 150 amp current draw

Yes, I know. And it'd dissappointing that they are misrepresenting the amplifier like they are.

Sorry about the link Stroker Boy.....

Here, this one should work: http://www.carsound.com/UBB/ultimatebb.php?ubb=get_topic;f=18;t=010998;p=1

Pay close attention to the posts by werewolf. On page two Werewolf does a very good job of explaining why this amplifier isn't really a "true" 15kw "RMS" amplifier. Even has the math to back him up //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif And yes, the developer posts in the above thread aswell, and werewolf does a good job of poking holes where holes need poked.

It's more like 15kw "burst" power because, as werewolf showed, the amplifier can only support 15kw of output for less than 16 seconds (using favorable assumptions). After that, like "regular" amplifiers, this amplifier is limited on power output by what it's drawing in....or less than 4kw.

And I believe the current draw is 350A, not 150A. Plus it's pulling very high constant current due to the need to constantly recharge that high internal capacitance. 350A of near constant current consumption is totally different than 350A of peak current consumption

Great info squeak. Should be a good read.

Thanks

'Tis a very good read if you have the time to read the entire thing //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

It's very long...but worth it.

180 pounds of junk it sounds like hey good ol rf ftw!

That's actually a very scary thought. I personally hope to never see it in one of my amplifiers.

I don't like the idea of my "1000w RMS" amplifier only being able to support 1kw of output for less than 16 seconds, and from there only being a 270w amplifier //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif Not to mention the higher constant current consumption.

doesn't sound to promising to me but what do i know...nothing so i listen to squeak

i dont like....to expensive..i mean dont get me wrong. it looks like a bad a$s amp but not as badas$ as they say it will be. i want to see the CEA rating on it

 

[Stroker_Boy 10+ year member]

i take back hte i want to see the cea rating i found it
