how do i get the most spl?

hello,

i hope someone can help me with this i just got my box built for 2 12" cerwin vega strokers dvcs my question is in order to get the most spl which way do i need to set my box ?subs firing up ?subs facing the rear ?or facing the front?

umm, what is the raw dimensions of the box, volume, is it vented, etc...what are the thiele small specs for your strokers etc....

it is a good rule of thumb that the further a bass note travels, the lower a note you will hear. The thinking is that the bass note must travel a Quarter of a wave before the note matures. In other words if your vehicle is large enough to face the woffers backwards, where they can reflect off the back and sides of your trunk then bounce back forward, you will usualy get a more powerful low, and in most cases a higher SPL. Go to a couple small shows, They are usualy happy to let you get in a test run, where the big competitions rarely have time to let you experiment.

Bass is mono ( don't really know where it's coming from. Put more focus on the power aspect of the setup. Make sure that the subs are getting the power needed and more important make sure that the voltage is consistent for the amplifiers. The lower the voltage the lower your SPL.

BTW, what vehicle is this box going into?

All of the above posts are things that need to be taken into consideration.  Philo provides good information.  But SPL related to box direction wont make a difference unless you get the enclosure correct.  Ive found that box direction will mostly help where the bass is heard, inside vs outside.  Personally, I go for feeling the bass rather than hearing it. 

If you are going to compete,  youre going to need much more help than can be learned  over this bulletin board.  If you just want your system to hit, youve already done half the work by using the Strokers.  Make sure you have plenty of power.  Normally CV's dont require much power to hit, however the Strokers are a different beast.  All this being said, the dimensions and type of box is critical to performance.   CV's tend to be effectively loud but need airspace for low notes even if tuned using reflex type enclosures.  Havent done a Vega in a while but as far as Ive seen, CV doesnt offer recommended sealed dimensions.  Hope you have plenty of space. 

Box dimensions are very critical. Optimum box sizes from manufacturer's are for normal listening at the frequencies they graph. IF your only using it for SPL and nothing else.... you need a very, very large enclosure for this. I know another installer friend of mine that used a single 12 " Crystal subwoofer and gave it abot 2000 watts in a 15 cu^ft enclosure with a 1.2 cu^ft port and got 148 db out of it. The frequency between 200 Hz and up sounded horrible but anything 200 Hz and down just rumbled beyond compare for just a single 12" sub. If you want a good enclosure program use Box Plot and punch in the dimensions for what you want.
