icedragoneer Posted May 18, 2018 Report Share Posted May 18, 2018 was wondering what the difference between rms power and nominal power is for example im looking at the orion xtrpro sup they are rated at 1250 rms 2500 nominal 5000 peak plz help when i was in the car audio game they just had rms and peak but then again that was the 90s lol Link to comment Share on other sites More sharing options...
Skullz Posted May 18, 2018 Report Share Posted May 18, 2018 RMS would be actual wattage made. In engineering, "nominal" is used to describe a measurement (or group of measurements) that matches the predicted value(s) withing the expected margin of error. More often than not, RMS ratings are not met. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...
AlpineNut Posted May 18, 2018 Report Share Posted May 18, 2018 RMS means the amount of power is required to not damage the sub, nominal means it can handle that amount for a long period without any damage, and peak means that is about what the sub can handle peak wise before it self destructs by either bottoming out or smoking out! 73456w9vbwevsdb sodtbsorutnvsd sdtuspdun sd d f gsdfiusd gdf n Link to comment Share on other sites More sharing options...

Crazy 8s Drums Posted May 19, 2018 Report Share Posted May 19, 2018 I would say that it could handle 1250w all day long...but probably not 2500. If it is what I am linking to, it doesn't appear to be built up enough to handle 2500 real musical watts for hours on end...but that is just my opinion. I don't like how they have those ratings listed as it implies some dishonesty in it. By 1250 RMS, that tells me it will handle what a 1250 CEA rated RMS watts all day. To know what kind of amps will do that, look at Ryan Blakenship, BigDWiz or Steve Meade's amp dyno videos. The AD-1 will help keep the makers honest on the amps and the subs will eventually follow suit. http://www.orioncaraudio.com/xtrpro-series-subwoofers-/593-xtrpro-104d.html Orion used to be fantastic stuff but more recently they have started doing the cost-savings made-in-china thing and have lost a bit of their reputation.

Crazy 8s Drums Posted May 19, 2018 Report Share Posted May 19, 2018 You might contact Orion and ask them this question. They have a warranty to honor if they lie to you and say it will do stuff that it can't. Orion XTR amplifiers Skar subs Link to comment Share on other sites More sharing options...

Mitchaford Posted May 25, 2018 Report Share Posted May 25, 2018 Lots of factors will determine how long you'll be able to play. Also consider your amp too. 2008 VW Jetta Team Fi 12 CT 4000.1 CT 125.4 PWX 6.5 80 PRS EB Flex 2/0 Second Skin ^^^ Build ^^^ Link to comment Share on other sites More sharing options...
