Experience with the RF "25 to Life" amps

[helotaxi 5,000+ posts]

Just curious if anyone has personal experience with the 25 to Life Punch amps, specifically the Punch 75. Not looking for a ton of power, though I know that they are quite underrated. How's the reliability? How low have you run them, impedance wise?

Well sir, I installed a 75 about a month ago for a friend. Compared to the original 75 ( I still have one //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif ) it's larger and a little heavier. Power wise my old one benched more power. We farted around with it pushing different loads compared to the original. The new one doesn't seem to get as hot as the original. I think they are rated at 120w at 4ohm mono. We benched it at 187w 4ohm mono, 262w at 2ohm mono. He is running it on a single punch hx2 at 2ohm. We haven't checked in box impedence so he could be getting some rise. But the amp is fine. Hasn't had a problem with it at all at 2ohm mono. He wouldn't let me try to drop it to 1ohm //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif My original will handle it, but he's a woose //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

RF birth sheets have the punch 75 rated at almost 700wx1 @4ohm bridged?

 

[dkguitarist 5,000+ posts]

that would be pretty good for the price. sd has them "on sale".

 

[ramos 5,000+ posts]

the birthsheets show max power at 14.4v don't they ? I only have a 12volt power supply. But we were using the rms meter too. I need to get a better power supply //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

For the 25-life punch75? That seems a bit much. I had only heard of 125-135 @ 4 ohms.

holy shit, thats ridiculous.

So they put out a lot of power. How do they sound, say compared to a top of line US amps, or arc audio amp?

Anyone running one of these on their front stage?

 

[Thetalkingshoe 10+ year member]

I'm thinking about running a 45 for my front stage.

 

[helotaxi 5,000+ posts]

The sound was mostly what I was getting at. They last RF amps I heard (7-8 yrs ago) sounded mechanical and just not very musical at high volume.
