Aeisuhr Posted February 2, 2017 Report Share Posted February 2, 2017 So with the how do i gain 3db question that is always asked, the answer has always been the same more effecient box, more cone area, or more power. Say you have 2 12s on 2k rms(1k ea) but upgrade cone area to 4 12s do you still get the gain with the same power 2k rms total(500rms ea)? No brands or anything in mind just a general question.

ShadeTreeMechanic Posted February 2, 2017 Report Share Posted February 2, 2017 Yes, in this case the power to cone area ratio doubled. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon) Link to comment Share on other sites More sharing options...
Aeisuhr Posted February 2, 2017 Author Report Share Posted February 2, 2017 i just didnt know if all 4 half power would be the same as 2 fully powered. And i know there isnt an easy way to determin this but a build i had in mind was with 4 12s but horizontal space is limited how much cancellation would there be with 2 and port forward with 2 on top Link to comment Share on other sites More sharing options...
shogen Posted February 2, 2017 Report Share Posted February 2, 2017 cone area is king in most cases.... rarely would you see lets say 1-12" sub beat out 2-12" on the same power.....

Triticum Agricolam Posted February 3, 2017 Report Share Posted February 3, 2017 The thing about cone area is you have to have box volume to support it. If you have a box with two 12" subs in it and you cut two more holes and put a couple more 12" subs in the same box you aren't going to gain much.

Aeisuhr Posted February 3, 2017 Author Report Share Posted February 3, 2017 i have about 7^3 after port displacement with what i was thinking thats a estimate because i havent worked out the port yet because i havent chosen the subs i want, still tring to figure out if 4 subs even with the cancelation from 2 being on top and 2 in front will still outperform the 2 alone with each only getting 500 rms i have 2t1's was thinking about just getting 2 more to go with them or if it will end up just performing like 3 Link to comment Share on other sites More sharing options...
nick1488 Posted February 3, 2017 Report Share Posted February 3, 2017 I don't see how there would be any canceling out of anything, because the subs would still be acting on the same volume of air. It shouldn't matter their position inside the box. Link to comment Share on other sites More sharing options...
tboorn Posted February 3, 2017 Report Share Posted February 3, 2017 the cancellation would most likely occur oustide of the box since the subs are firing different directions therefor bouncing off different walls first, so theoretically at certain frequencies they could cancel each other out, but i wouldnt count on it ruining your system Fidelity Built to Last Team Sound Asleep 24Runner Build Log: http://www.stevemeadedesigns.com/board/topic/196657-24runner-sleeper-system-lots-of-fi-neo-dd-focal-new-video-w-juicebox-lithium/ 2 x 12" Fi BTL N2 / 2 x 12" Fi BTL N3 2 DD M3b Maxwell 2.7V 3000F Supercapacitors Pioneer DEH-80prs Focal P165 V30 components Rockford Fosgate T-400.4 Link to comment Share on other sites More sharing options...
