Mikey Bates Posted April 10, 2012 Report Share Posted April 10, 2012 Lets say i have two 12's. each seperate. and one rms at 250 and the other at say 1000. tthe xmax on the little one is obv smaller. but here the question. if i give 250rms to the 12 that is rated at 250, and give 250rms to the one rated at 1000. would the smaller rated one perform better because its getting the right amount. or would the bigger one still be louder even at the same rms as the smaller one. orrrr. would they technically be about the same. given box is the same and s optimal for both (somehow) and same car and song, and amp.

IH8PunkRok Posted April 10, 2012 Report Share Posted April 10, 2012 this is a decent question and as always it may not be the same from one setup to the next BUT i would think the one getting rms would prove to be better than the one not getting rms one thing ive noticed is at rms or under subs can play a much wider range regardless of box because their limits are not being reached. once you get over the rms though you can watch your lows disappear Quote -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build Link to comment Share on other sites More sharing options...
Jaloosk Posted April 10, 2012 Report Share Posted April 10, 2012 They would be the same. It's like driving a honda civic and a F1 car both at 50mph. One is CAPABLE of going faster, but they're still going the same speed. Quote "Cheap, good or fast. You can only pick two out of three." "Have money? Love story! No money? I'm sorry."

AI James Posted April 10, 2012 Report Share Posted April 10, 2012 not true. it comes down to efficiency... for instance in testing a 1000 watts on a fi q and 1000watts on a BTL the BTL was always louder Quote Link to comment Share on other sites More sharing options...
Noob_On_Droid Posted April 10, 2012 Report Share Posted April 10, 2012 The two key variables here is the larger speakers motor and suspension. If it has a very stiff spider pack designed to keep the cone under control at or above 1k it will restrict output on the driver at 250w. Whereas the smaller driver will have the correct motor and spiders to be most efficient at that power. If the big driver has a relatively soft spiderpack for a 1k driver it may perform closely with the smaller driver because the extra motorforce on the larger one will compensate for the stiffer setup.

Noob_On_Droid Posted April 10, 2012 Report Share Posted April 10, 2012 Haha^^^^ or motorforce is king I've never had such definitive results it all depends on how big the big driver actually was. Learn something new everyday. Quote Link to comment Share on other sites More sharing options...
Mikey Bates Posted April 10, 2012 Author Report Share Posted April 10, 2012 would it stress the amp but trying to push the tougher sub? Quote Link to comment Share on other sites More sharing options...

Mikey Bates Posted April 10, 2012 Author Report Share Posted April 10, 2012 so heres why im asking. i have 2 12 mtx sub in a sealed box that can take 400rms (so they are underpower actually) and my amp gives 250......im putting in a 15" skar sub that is 600rms (planning on pushing it to about 1000 daily) in a ported box at 35hz. even though the sub is less area, it is ported, and take more. so hopeing itll be way way louder....but for now i only have that 250rms amp. would i be better off keping my set up and waiting for a bigger amp?

pa-pa-platypus Posted April 10, 2012 Report Share Posted April 10, 2012 1000 watts is more than enough on that sub...build a custom box for it and never look back Quote This isn't teeball. YOU DO NOT GET A TROPHY JUST BECAUSE YOU SHOW UP. Put the work in and then maybe get the respect when it has been earned 151.6 with single 12 at 41 hz 153.2 with 2 12's at 43 hz power: dd m4 Link to comment Share on other sites More sharing options...
