I just bought a single 15 " RE SX and im looking for people's inputs on box size ( Dimensions) Im going ported, so that is a must. Any ideas are or links to other pages/threads that have already had this conversion are welcome to be posted.

****This is for Pure SPL****

Running 2 Ultimate T3 1000D Amps (around 3800 RMS)

 
bandpass tuned at 70hz

make sure the sealed cavity is no more than 3 cubes...and make the ported cavity somewhere around 5 cubes....with 150 square inch port 7inches long

u should be good 2 go

80

 
Someone's a little bandpass happy...

Bandpass won't always be the loudest setup in our experience...//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

And if you are going for all out SPL...it's not as simple as tuning it to a frequency and getting good results...they take a lot of work to get right...

 
And yet you so rarely see a serious SPL competitor using bandpass...
Its not that simple. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
It's class dependant really. A lot of Europeans are using bandpasses and they have the loudest cars around //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I've still got some design plans from the loudest car in the world....//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

 
I've sent one more for burps...//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
Mine wont take my two nine.1's for burps. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Hence why i have the type-r now, which takes it fine.....
