Too Much Power


Please bear with me as I am nowhere near an expert at this type of thing...

I recently read a review of the PS Audio Stellar M1200 mono amps. I was somewhat taken aback by their power rating of  600 watts at 8 ohms/1200 watts at 4 ohms. Made me wonder what, if any, are the drawbacks to that much power? Welcome your thoughts...

Except perhaps for Quads, you never blow a speaker from power but rather from clipping. Check out the way tube and solid state amps clip and tell which type of clipping most would deem more tolerable. 

You most certainly can blow a speaker from applying excess power; it is not always the case that tweeters are the drivers to blow because clipping introduces high frequency harmonics.  I wish people would be cautious around their high-powered amps.  The most surprising thing that I've seen is speakers where none of the drivers were damaged by extremely high power being sent through the speaker, but, the crossover failed from the excess heat; that heat was enough to completely melt the plastic bobbin of an inductor which left a lump of wire sitting in a pool of plastic.

I have a post it note on top of my preamp “scotch or beer, lower the volume”

 

had nightmares in the late 80’s early 90’s with smaller speakers. Not with my,modded CV D-8 pairs. Power hungry monkey coffins.

After the right side binding posts literally turned to melted red/black crayon on my old Onkyo m504, I saved and have never had an amp with less than 250+ WPC!

 

ONE EXCEPTION, bought a 20 year old pair of odyssey stratos many many years ago,sat in my basement for a few years til I could save the scratch ,….and proving Klaus is a damn good dude, on his way back from an audio show , he stopped at my house, picked up the amps to be upgraded! Called me in a month or two, we met almost halfway so I could pick them up.

Those,amps rated at 180 or 200 WPC ?? Are the lowest watt amps I’ve had in years. Will say, ….they do drive my modded D-9 pair very well, where as other amps have shown a lot of strain and some just barely chugging,along.
they are about 3.5 - 4.5 Ohms, power hungry little buggers! The upgraded Odyssey kismet really control them nicely, I’m not sure the output of the amps at 3- 4.5 Ohm load, but they get somewhat warm after 3 hours of jamming’ thin lizzy, frank Marino, scorpions, Gary Moore, venom, Motörhead, tank, forbidden, riot, onslaught, etc etc etc…. They,do hold up well, and never miss a beat. I would think the kismets would hit 325 - 350 at 4 Ohms. Maybe a little more as the impedance drops below 4 Ohms.

Used 2 carvin dcm 2500 pair as monos, they didn’t last too long being pro amps, I was happy with the open sound and guitar n bass crunch.
The Emotiva xpa-1 pair would get real hot,….had to put fans on them.

QSC pl-340 is reliable and will drive anything I hook her up with.

anyway, back on track, sorry for the hijack……
