you dont need a huge box to be louder...but if you go ported it def will be louder

 

A properly build prted enclosure has the ability to get nearly twice as loud and produce much lower frequencies than a sealed box can. You shouldnt be scared to build one, its in fact very simple. You can get a design plan from someone online. You can have your local hardware store cut the wood for you, and then all you have to do is glue and screw. Building a custom ported enclosure is the cheapest and most efficient way to enhance your bass...

 

oh im not scared about building a custom box, ive done many including my grand prix, and my brothers eclipse show car, i just dont have the time to do it myself thats all. i planed on building something in the future, but imnot sure if i want to upgrade my subs yet or now, mine are pretty nice, and relaly loud as it is.

 

bigger box can be louder but just because you make a huge box doesnt make it louder, there is a such thing as top big, if the box gets too big its almost like running it in free air. so dont let people mislead you. and a ported box will make it louder
lets say a sub needsa 2 cube boxand you stick in a 7 cube box its not going to be louder because you have abigger box.

 

I think generally they say porting will add around 3db......not twice as loud.

your saying if I hit 140 db sealed....port it and i will be at 280dbs?

 

280db is not twice as loud as 140db...decibels work a little diffirently then that...

 

Doubling the SPL is not going from 140dB to 280dB... That would actually be close to 12x gain in SPL.

A deciBel by definition can be boiled down to a ratio of powers/pressures/etc (dB = 10 * log(P1/P0) where P0 is the reference power/pressure/etc level and P1 is the power/pressure/etc level being sampled). Pressure is proportional to the square of SPL (sound pressure level) in this case. +3dB corresponds to a doubling of pressure. +6dB is 4 times the ppressure and since pressure = SPL^2, this also is double the SPL. So, to double the SPL, you actually need an increase of 6dB.

You are correct in saying that a 3dB gain is not going to be twice as loud, but it is a lot closer than you gave it credit for. It will be 1.414 times louder in SPL terms.

 

thank you for that kyle. now I dont have to post it. Thanks bud!

 

Hey, I know a thing or two about what all of you ear bleeders are talkin' about from time to time. LOL

 

here is a video of my ported box
