Haunz, why don't you buy one and prove Kevin false? And no, they shouldn't give you one to test with for free.
Until then, Rockford is a reputable company and if they made false claims it would only hurt them.
Like Kevin said...this is new patented technology and it could very well produce the power stated at the draw stated.
Unless proven wrong the amp is simply an amazing piece of equipment. Out of the price range and capabilities of 99% of audiophiles (just like the Phoenix Gold Amp and the MTX Sledgehammer)
Until one is put into action and it's proven false there is no reason to not believe the numbers. Once again RF is a reputable company and there is no reason to not take them at face value.
Agree to disagree and take the "wait and see" approach.

I don't need to buy one of these for 20K to understand ohms law...
I saw some pics on another site... apparently this amp uses 12F+ of capatance after the diode bridge in the psu.... (which makes alot of sense)
However, this idea is nothing new... open up any amp and you will find the same thing.. (although probably not to the same degree)
According to RF though.. this is something completly new and amaizing which it is not, and in fact any amp will average far less average current draw compaired to its peak draw using program material...
Bottom line is that it might be an awsome amp but the marketing fluff really gets to me.... its more then likely just 4 boards stuffed in a huge chassis with alot of capatance after the rails...
And its 'patent pending' BTW...

The information you posted said:
"Patent Pending Power supply design -- consumes 5 Times LESS peak current of other amplifiers for the same power output (with music)"
Note the "with music" part. So the amp draws less current under non-CEA2006 conditions. But at CEA2006 conditions it will be greater.

Well IMO it would be perfect for SPL because of the extra capatance on hand after the rails....
I just don't think its really break through technology or really any better then having lots of capatance/battery power on the other side of the psu

To maybe put the things capactity into perspective
rail V I read is 140 with say 12F of capitance = 235200 joules on hand... 3db drop in rail V and we would be left with 99V for a usable 117588 joules before a major drop in level..
we will say she is operating at full boar with PROGRAM material at 33% duty cycle with 50% effeciency (what class amp is this again?)
By my math (err Iam kind of baked today [img]tongue.gif[/img] ) we would have about 12 seconds of reserve energy before a major drop in level with music if our battery/alt suddenly fell below 10v from 14... (>3db)
With a pure tone at full tilt (spl) ur probably looking at about 1/2 that time assuming 80% effeciency. Also its said to put out up to 26kw under hard clip ???
(Those reserve caps aint gonna last long [img]tongue.gif[/img] )
Those #s are relative as batt/alt v usually dosen't just drop right off...
A more fair compairison might be how much juice she will give up and time before the battery kicks in assuming a major drop in alt output... (would be compairativly much less time)
I have also completely ignored IR losses which would probably be a major factor.. apparently the thing uses multiple 2.7V 400F caps IN SERIES so Iam a little skepticle....
I must admit response to transient demands must be awsome... I just wonder if its 15kw awsome... or $20K awsome... [img]graemlins/2xblown.gif[/img]

new inovation or not you cannot produce more power than you put in
its pure and simple
cannot be done
sure you could store power to be used later as a battery does
and thats what there probably doing and calling it a new thing and painting it all nice new colors
like they reinvented the wheel all over again
oh my look at me
please talk all about me because im the magic amp
i suck static electricity out of the air to drive speakers and drop the consumed power down

............roof rack mountable and off a stock alternator at sea level, will potentially do 40 billion watts before detonating like a giga ton bomb......... destroying the world..........no, no, destroying the universe.
BTW, not available in Canada cause it's too cold.

Tom,
I speculate that you were drunk when you made this post...
You are, or work for, a distributor. You wouldn't openly hack on another manufactures product would you? I didn't think so. That would not be very professional.

Kevin.............. you are kidding right?!?!? Seriously, you're joking around rite ?!?!?!? You ARE saying that with a stiff upper lip of humor.......... !??!?!
What you said is as stupid as me saying..........you got one of your buddies to start this thread to generate more interest in RF. Yeah, yeah...... that would be a stupid thing to insinuate.
