Shanerator Posted November 29, 2016 Report Share Posted November 29, 2016 ok, experts, please tell me once for all.. i have now 1 sub giving it 400 rms power in single sub enclosure.. I will change that to 2 subs enclosure with 2 identical subs in it and will give each one 400 rms power. So i will have 2 subs instead of 1 and all together 800 rms instead of just 400.. Is this now 6 db increase cuz i doubled the cone area and doubled the power or is just 3 db? Tnx Link to comment Share on other sites More sharing options...
ShadeTreeMechanic Posted November 29, 2016 Report Share Posted November 29, 2016 Basically that would be 6db. Of course you still have a ton of variables that will effect it. The box and impedance rise come to mind along with the gain from the car will be different etc. 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...
Shanerator Posted November 29, 2016 Author Report Share Posted November 29, 2016 ok understand that.. just wanted to confirm this basic 3 vs 6 db thing.. so the concept is.. if you just double the power to one speaker, only 3 db increase, but if you add one speaker and give it the same power, 6 db increase in perfect conditions? is this rule still apliable in ex. if we had 4 the same woofers (400 rms each) with total of 1600 wats rms? Is this 12 db increase in comparison with just 1 sub getting 400 rms? Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted November 29, 2016 Report Share Posted November 29, 2016 Yup, you've got it right. Like ShadeTree said though, what you get in practice isn't always the same as what theory says you will get.

Shanerator Posted November 29, 2016 Author Report Share Posted November 29, 2016 ok tnx very much. Just one last question. It is the same for example with tweeters? like 1 tweeter 50 rms and then another 50 rms. Also 6 db? or no because they are on seperate sides..

Speakers (tweeters, mids, subwoofer, etc) have to be within a certain proximity of each other for their output to combine properly. The higher frequency being produced, the closer they have to be. With tweeters, since they are on opposite sides of the vehicle, they aren't going to combine perfectly. They will be louder than just one, but its not like subwoofers.
