michigancapri92 Posted November 11, 2011 Report Share Posted November 11, 2011 ok ive been trying to thin about this and i would really like to learn the science behind it. if you take like a 100 watt 12" subwoofer and a 1000 watt 12" subwoofer ... what makes them louder? their both 12" cones moving air so what really makes them louder ?

bre2ts Posted November 11, 2011 Report Share Posted November 11, 2011 I'm not sure myself But I would assume motor force, soft parts to withstand motor, coil to with stand heat. But like I said I'm not sure Feedback 1 | Feedback 2 you win some, you lose some Link to comment Share on other sites More sharing options...
AdamTheAudioMan Posted November 11, 2011 Report Share Posted November 11, 2011 Mostly the motor, but here are some others: High sensitivity ,High thermal power rating, large mechanical stroke = high displacement... UNDER-CONSTRUCTION ''Old School Build'' maybe it sounds like an 18 cause theres 3 fucking "port" holes ghetto drilled in the "box" 190 db when your done? Yea that's the lowest decibal ill be satisfied with when I'm done like I said its stage one and I lost my job u guys should consider shit instead of just talk it lmao Link to comment Share on other sites More sharing options...
AA98hoe Posted November 11, 2011 Report Share Posted November 11, 2011 There was an anology explaining this to me sometime back.. say you have a 12 in shovel and your pushing snow. Well the 100w sub will push it say 2ft were as the 1000w sub can push it 10ft. I think it has to do with motor force and cone force.

dblovah51 Posted November 11, 2011 Report Share Posted November 11, 2011 I would thinks its a combination of coil,motor force, suspension, and cone structure..imo curious to know for sure myself! 2004 trailblazer 4 FI BTL 18s (2) DC 10.0k xs power d3100s mechman 270 158.2 @41 Link to comment Share on other sites More sharing options...
IH8PunkRok Posted November 11, 2011 Report Share Posted November 11, 2011 it all has to do with speed and the amount of air the cone can move the more air the sub can manipulate the easier it will be to get loud (basic principle behind cone area is king) the speed though is the trick and honestly that part i havent quite figured out yet. but there is a reason why if you put more power to a sub (even if it was at xmax on lower power) it will be louder -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...
EdgarG0721 Posted November 11, 2011 Report Share Posted November 11, 2011 When u say 100w an a 1000w ur powering them with the same power each if not then the difference will be power. But that's a good questions I would also like to know the answer if on same power. Link to comment Share on other sites More sharing options...
Wicks Posted November 11, 2011 Report Share Posted November 11, 2011 Running an alternating electrical current through a coil of wire will produce a varying magnetic field. That magnetic field interacts with the speaker's permanent magnet and therefore pushes or pulls the cone. The 1000W sub can handle more thermal stress so therefore you can provide the sub with more voltage which induces more current. The more current through the sub will produce a stronger magnetic field which can react quicker with the permanent magnet. Efficiency of the sub also plays a big role so you make use of that power rather than just burn it off in heat. Since the 100W and 1000W subs have the same cone area, then to be louder the sub needs to move more air. Of course the enclosure also affects how far the cone can travel and its tuning frequency.

94retta(219) Posted November 11, 2011 Report Share Posted November 11, 2011 I to would like to know this. The way i think about it is prolly wrong, but if i had to guess if say its how vilent the sound waves them self are. BUILD LOG Link to comment Share on other sites More sharing options...
Quiet Posted November 13, 2011 Report Share Posted November 13, 2011 The key principle in making sound is how much air can you move Most of what makes a sub work has been said, but I think it's like this: RMS Rating = How much power a subs coil can handle SPL 1w1m = How much sound it will reproduce with 1 watt Sd = Cone area, how much surface radiates sound Xmax = Stroke. How much away from rest the cone moves to sweep air Fs = natural resonant frequency of the sub... typically can help indicate how low it will play, but don't take this literally, much more is involved here! BL = motor force available for the coil to "work on". If you have a weak magnetic field, all the power in the world won't do shit for you. So those are the ingredients, you just have to figure out in your mind how they work together. The more air you move, the higher the SPL. The fun part is when you apply these characteristics you might expect one reaction but get another. Add to that how each manufacturer measures everything differently... well have fun with that. 2007 Pacifica Rebuild. Less quiet. Still not loud.
