rms power...

[taylor 10+ year member]

why the bloody hell is everyone so concerned about running too much rms into their woofers....it's all in the application, i am running 700 watts to a single 8 inch sub, for sq it's great and **** clean....i ran 1060 rms to a type r 15.....no prob....why do people always claim to blow stuff when they put too much power to it....it's all in the application, proper box size, and peoperly set gains.....people buy the 1200 watt amp if you want to, even if you are running 2 12 wo's, if set properly and not pushed super hard it will work fine....why buy say a 400 watt amp because "the rms is 125" when the 1200 will work fine and allow you to upgrade later....

Normally people buy smaller because of money.. if we all had unlimited funds we would buy amps that could run 5000 rms and worry about speakers later.. It's not that simple...

And people worry about putting too much rms into speakers because they don't want to blow their systems.. Some companies might say their speakers handle 500 rms when they take 750, but others might say they take 500 rms when they take 450.. you put too much and you blow it.. no way to know what a speaker will take till you push it.. or find out what companies/speakers are underrated..

Why are you upset about this?

because, read about how much i am running to a single 8, and how much i have ran to my type r.....the rms on the type r was 500, the rms on the 8 150....it's all in the application, gains, box etc, i have never blown a woofer in my life by having too much power....

so?

if you have your gains matched to the input voltage and have 500 rms to a 100 rms speaker, you might well blow it.. yes..you can turn down the gains to avoid blowing speakers, but people that are new to audio have NO idea what is going on.. Matching rms of amps to speakers is a good idea..

There are SOOOO many other things to be upset about, I'm not sure why you are upset about people trying to be careful and not blow speakers..

yeah but 700 watts is what my amp is rated at a 4 ohms, the sub is rated at 150 rms 300 peak....figure that out....it's application....

i suppose....i even know a guy who is running a 1000/1 to 2 jl 12 wo's....it sounds great.....

Of course, most people don't know that when you turn the volume up, the input voltage increases, which means that you have to turn your gains down. Most people will set their gains at 1/2 thinking, "Oh, it's only at half. It'll be fine." Except they don't know what the gain actually means ...

Hell, I had a pretty good idea what gains were all about.. but not as detailed as I know now (thanks to Jmac //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif ).. Your average joe has no clue..

Wrong. I blew 2 Infinity Kappa Perfects sending them a little over 375....it all depends on the subwoofer, and then the application comes into play.

i bet that sub could handle 500 watts RMS all day long if its put into a really small sealed box

It was a small sealed box, each sub had 0.8 cuft after displacement

hrm..weird..a friend of mine runs 2 of them with REALLY SMALL sealed box (and i do mean sealed) with a US acoustics USX4085 to each sub (1 bridged channel to each coil) and they ran fine, even when pushed hard. i can take pictures if you want me to prove it //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Because you are not running a pure '1060 rms' to the driver for an applicable period of time that it would allow damage. Don't assume because it hasn't happened to you yet that it cannot happen.

It is not all about enclosure size, and stating 'correctly set gains' means that you have the level of output set back far enough to not mechanically or thermally destroy the driver, therefore you are indeed not geting the true 700 into your 8", or the 1060 into your 15".

Some don't wish to spend the extra on a larger than needed amplifier. Some are content purchasing the equipment that matches their needs at that point in time.

Different levels of thought for different people is all.
